fix(ui, localization): improved semantics on message - #2928
Conversation
…n readers
A message row conveyed its sender and direction only visually — through row
alignment and bubble color — so a screen reader announced the content and
nothing about who sent it. A deleted message was worse: there was no way to
tell whether you or someone else had deleted it.
Each row is now exposed as one labelled node reading "You said, <body>,
<time>" / "<name> said, <body>, <time>", with the deleted placeholder phrased
without the "said" ("You, Message deleted") since the sender never authored
it. The body comes from the existing AccessibleMessagePreviewFormatter, so
attachment-only, poll, location and deleted messages are all covered and a
consumer's custom formatter still applies.
The label is a non-container Semantics annotation with explicitChildNodes
placed inside the row's PlatformWidgetBuilder: it merges into the row's own
tappable node on mobile and forms that node itself on desktop and web, giving
exactly one labelled stop either way, while the attachments, reaction chips,
quoted message, replies row and sending status stay individually focusable.
The fragments the label now speaks — message text, deleted placeholder,
footer username, timestamp and edited marker — are wrapped in
ExcludeSemantics so they are not announced twice.
Trade-off: excluding the message-text subtree removes the per-span semantic
nodes Flutter creates for inline markdown links and mentions, so those can no
longer be activated by a screen reader. Their text is still read as part of
the row label. The SwiftUI, Android and React Native SDKs all collapse the
message text the same way.
Adds a public `semanticsLabel` on StreamMessageItem / StreamMessageItemProps
to replace the composed label, and four AccessibilityTranslations strings with
native implementations for all 11 supported locales.
Resolves FLU-592, FLU-593.

…ivider Device testing surfaced two things the first pass got wrong. The delivery status was a focus stop of its own, so a screen reader user had to step through a bare "Read" tick to get past a message. It is now appended to the composed row phrase and the icon is excluded from the semantics tree, so an own text message is a single stop: "You said, Hello, Today at 3:00 PM, Sent". All three sibling SDKs do this — SwiftUI hides the indicator and folds the status into the bubble label, Android merges the icon's leaf description into the merged row, React Native splices it into the grouped footer element. StreamDateDivider announced a clock time it never displays: showing "Yesterday", it announced "Yesterday at 1:06 PM", because StreamTimestamp falls back to formatRecentDateTime. It now announces the date as shown, and is marked a header so days can be jumped between. SwiftUI and Android both announce the date only and both mark the separator a heading; React Native announces the date only without the header role. A deleted message no longer announces a time or a status either: it renders no footer, so neither is on screen. This is a deliberate divergence — the other three SDKs do announce a time for deleted messages, but they also still render a footer for them, so their announcement matches their UI as ours now matches ours. Traversal order and the attachment tiles are unchanged: measured, the row summary is already announced before its parts, and each tile stays reachable one level deeper, which is the model Android documents and enforces. What is still missing is labels on those tiles — the image and gallery attachment widgets emit no semantics at all, so a tile announces nothing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… readers Image, video, GIF and gallery attachments in the message list carried no semantics at all. The tiles were focus stops — they open a preview on tap — but announced nothing, so a screen-reader user stepping through a message with photos heard a run of silent stops. Each tile now announces its type, reusing the labels the composer previews already use, and within a gallery its position: "Photo, 2 of 5". The position is what makes otherwise identical thumbnails tellable apart. The "+N" overflow badge is excluded from the semantics tree — the tiles' "of 5" already says the gallery holds more than it shows, so the badge would only add a stop reading "plus 2". Grounded in the sibling SDKs, which all label their tiles: SwiftUI announces "Attachment 1. Image from Yoda, sent at 18:45. Activate to open."; Android uses a leaf "Image attachment" description with an "Open attachment" click label; React Native uses "Gallery image" with a "Double tap to open" hint. None of the three announces a total, and SwiftUI's overflow badge is unlabelled — the "of N" is ours. Voice recordings, files and link previews are untouched: they render their own text or interactive controls and already announce something. Adds `attachmentPositionLabel` with native implementations for all 11 locales. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The deleted branch of StreamMessageContent returned the placeholder bubble on its own, dropping the header and footer slots the caller passes in. The design shows a deleted message with its delivery status and timestamp below the placeholder, exactly like any other message (Figma node 6371-306190, "Mobile / Message Container – Outgoing", whose message stack contains the bubble plus a "Message Container / Delivery Status" instance). Both slots are now wired through, so the metadata is back on screen. The screen-reader phrase follows: it announces the time and the status again, which also puts us back in line with the other SDKs — SwiftUI announces "You, Message deleted, at 6:45 PM", and Android and React Native both render a footer for deleted messages too. This supersedes the earlier decision to drop the time from the announcement. That was made to match what was rendered; the rendering was the bug. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A message that was edited and then deleted showed "Message deleted • Edited", describing history the reader can no longer see. The marker is now suppressed in the footer, in the composed screen-reader phrase that mirrors it, and in the metadata-visibility default — an invisible marker should not force the footer visible on a stacked message. Both sibling SDKs do the same: SwiftUI guards the label with `&& !message.isDeleted` (MessageListHelperViews.swift:83) and Android with `message.messageTextUpdatedAt != null && !message.isDeleted()` (MessageFooter.kt:81). Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The quoted-message preview announced only the quoted author's name — "Han
Solo" — leaving a screen-reader user to guess why that name was there and
whose message was being replied to. It now announces the relationship the
preview stands for, merged with the quoted body into one phrase:
"Han Solo replied to your message, are we still meeting tomorrow"
"You replied to Leia Organa's message, are we still meeting tomorrow"
This follows Android, which is the only sibling SDK that does this properly —
`QuotedMessage.kt:154-178` picks between `..._replied_to_your_message` and
`..._replied_to_their_message` on whether the *quoted* message is the current
user's, and substitutes "You" for the replier when that is the current user.
The same four-way matrix is implemented here. SwiftUI reads its visible
composer-phrased title ("Reply to Alice") and never says whose message it was;
React Native announces the title only and drops the quoted body entirely.
`StreamQuotedMessageProps` gains `replyMessage`, the message doing the
quoting — the preview needs it to name the replier. It is optional: without it
the preview announces the author's name as before, so a consumer building the
widget directly is unaffected.
Adds `repliedToOwnMessageLabel` / `repliedToMessageLabel`, with native
implementations for all 11 locales. Both names are parameters so each locale
forms the possessive itself.

Six bullets across two files described one piece of work. Replaced with a single entry about the message-list screen-reader improvements, naming the two new public parameters, and one grouped entry for the new localization strings. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
While attachments upload, StreamMessageSendingStatus shows a progress count
("Uploaded 1 of 2 …") in place of a tick. Excluding that footer from the
semantics tree flattened it to the generic "Sending" in the row phrase, losing
progress a sighted reader can see. The phrase now mirrors the footer exactly,
same as it already does for the sent/delivered/read ticks.
Not added: upload state on the individual attachment tiles. Neither sibling SDK
puts it there — Android's tile description is a pure function of the media type
(MediaAttachmentContent.kt:470-490) and SwiftUI's formatter has no upload-state
input at all (its three metadata structs carry no state field), so a tile reads
identically whether it is sent, mid-upload, or failed. Keeping the state on the
message, where it is computed once, also avoids re-deriving it per tile.

A failed message announced nothing about the failure. StreamSendingIndicator has no failed branch, so the footer shows no tick, and the failure is conveyed by an error badge on the bubble — a bare exclamation icon with no text of its own. A screen-reader user heard a message identical to any other and had no way to learn it never went out. The row phrase now ends with "Message failed to send" in place of a delivery status, on the same condition that shows the badge (a failed send or a moderation bounce). The wording is the phrase both sibling SDKs use, though neither reaches it from the message list: Android's `..._semantics_message_status_failed` is gated out of the footer by `shouldShowMessageStatusIndicator()`, and SwiftUI has no failed status at all — `MessageViewModel.swift:255-266` collapses `.pending` and `.failed` into "sent", announcing a failed message as sent. Adds `messageFailedStatusLabel`, with native implementations for all 11 locales. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…and-direction Three conflicts, all with the message-translations feature (#2870): - `stream_message_content.dart` — master added `showTranslatedText` to the `StreamMessageText` call this branch had wrapped in `ExcludeSemantics`. Kept both: the wrapper and the new argument. - `stream_message_content_test.dart` — master dropped the `stream_message_content.dart` import, now that the barrel exports it. Took master's removal and kept only this branch's `stream_message_deleted.dart` import, which the barrel does not export. - `stream_chat_localizations/CHANGELOG.md` — both sides added an `✅ Added` bullet. Kept both, master's first. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The message-translations feature merged from master lets the reader toggle a translated message back to its original text, and can be disabled entirely by configuration. The composed row phrase ignored both and always announced the translation, so a reader who toggled to the original heard text that was no longer on screen. The phrase now resolves the text the same way `StreamMessageText` does — the translation only when one is actually shown — so it follows the toggle. The translation annotation itself needs nothing: it is an interactive `StreamMessageAnnotation`, so it is already a focus stop of its own announcing "Translated from German" and "Show original". Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Reading it, it is not obvious that the bare body is right for a deleted message. It is: the formatter already returns "Message deleted" as the body, so the announcement stays complete and only loses the attribution there is no name for. Noted too that `User.name` falls back to the user id, which makes the branch close to unreachable. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…text The composed row phrase fell back to `'en'` when the reader had no language set, so it announced the English translation of a message whose bubble showed the original — `StreamMessageText` passes the unset language straight through, and `translate` returns the message unchanged for it. Passing the language through unchanged keeps the two in step, and leaves no default language behind in the package. The existing translation test was passing only because of that fallback: its reader had no language, so it asserted a translation the bubble would not have shown. The reader now has one, and a second case covers a reader without. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

- An empty `semanticsLabel` is documented as leaving a row unlabeled, but an own message still had its delivery status appended to it, announcing a bare ", Sent". Empty now counts as having no label, like null. - The date-divider semantics tests classified dates against a live clock, so a run crossing midnight could reclassify "Today". Pinned with `withClock` and a fixed date; verified the frozen clock drives the assertion by shifting the date and watching the label change. - Norwegian `repliedToMessageLabel` said "meldingen til <name>", which can read as the message *to* that person. Changed to "meldingen fra <name>". Still wants a native-speaker pass, like the rest of the batch. - Dropped an always-matching pattern branch around the footer timestamp; `Message.createdAt` is a non-nullable getter.

`_MessageRowSemantics` compared two nullables, so a message with no author read by nobody signed in matched on `null == null` and had a delivery status appended: "no one sent this, Today at 3:00 PM, Sent". Both sides are now required to be present before their ids are compared. Every other site that makes this comparison already guards the sender first (`stream_message_footer.dart:95`, `stream_message_item.dart:718`) or compares against a non-null id, so this was the only one affected.

…and-direction One conflict, in `stream_quoted_message.dart`. Master's import lint flipped from `always_use_package_imports` to `prefer_relative_imports` inside a package's own `lib/` (#2929), converting that file's self-imports to a relative block. This branch had added two more to the old package-import block. Took master's relative block and added both as relative imports: `../stream_chat.dart` and `../utils/extensions.dart`.

The branch order deciding whether a message reads as sending, sent, delivered or read was written out three times: once in StreamSendingIndicator to pick an icon, once in StreamMessageSendingStatus to decide between upload progress and that icon, and once again in the row announcement added by this branch. The three had already drifted — only the announcement knew about a failed or bounced send. Move both decisions onto Translations as attachmentUploadProgressLabel and messageDeliveryStatusLabel, and have all three read from there. The icon now takes its semantic label from the same call that the row announcement uses, so what a reader sees and what a screen reader hears cannot describe different states. No behaviour change. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The footer and the message bubble were excluded from the semantics tree unconditionally, on the assumption that StreamMessageItem always composes a row label that speaks them. The class doc said as much and asked custom layouts to re-expose them — but the SDK contains such a layout and it was never updated: StreamGiphyEphemeralMessage builds StreamMessageFooter directly, so the giphy preview's timestamp and delivery status announced nothing at all. Passing an empty semanticsLabel, the documented way to leave a row unlabeled, silenced a message the same way. Replace the advisory contract with an enforced one. StreamMessageRowLabelScope marks a subtree whose metadata a row label already speaks, and the fragments consult it: inside one they step out of the semantics tree as before, outside one they announce themselves, since nothing else would. A row only claims the scope when it actually has a label, so the empty-label escape hatch now hands the announcement back to the parts instead of dropping it. Also records why the message text leaves the semantics tree at all. Collapsing it costs the inline link and mention spans their own nodes, so a screen reader can read a link but not activate it. That is deliberate: a focus stop per span, each repeating text the row just spoke, makes every message more tedious to move through than it makes the rare link easier to reach, and the SwiftUI and React Native SDKs collapse plain text the same way. The new tests fail on the parent commit and pass here. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The row announcement tracks ChannelClientState.readStream so the delivery status it speaks stays in step with the icon in the footer. It reads that stream through a BetterStreamBuilder with no noDataBuilder, which falls back to SizedBox.shrink() when it has no event — and the builder wraps the row's child, so the whole message disappeared rather than just the status. Channel.state is null until the channel is watched, and StreamChannel renders its child during that window when showLoading is false, so an own message could render as an empty box in a supported configuration. A probe against master finds the message text; on the parent commit it finds nothing. The same pattern is used in StreamMessageSendingStatus, where losing the subtree only costs a tick icon; wrapping the row content in it is what made it harmful. Fall back to the row with its label and no status, which is what the footer shows in the same state. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The row label appended a delivery status to every own message, without consulting the resolved metadata visibility. A stacked message at the top or middle of a run hides its footer entirely, so the row announced a "Sent" that is nowhere on screen — the opposite of the rule the rest of the announcement follows, that it mirrors what was rendered. Gate the status on whether the footer was actually built. The timestamp stays unconditional: it is the one piece worth announcing even when hidden, so that landing on a message in the middle of a run still tells you when it was sent. That split matches the SwiftUI SDK, whose accessibilityLabel(showsAllInfo:) always speaks the sender and time and appends the delivery status only for the message that displays it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The row label took the message text straight from the model, so a screen reader spelled out markdown syntax the bubble had already resolved. A message reading "check our docs and this now" on screen announced as check [our docs](https://getstream.io) and **this** now with the brackets, the parens and the whole URL read aloud. Every message carrying a link, bold, code or a heading was affected. Before this branch RenderParagraph announced the rendered text, so this was a regression. Resolve the text through the markdown parser and take the plain text it renders as, using the same gitHubFlavored extension set MarkdownBody defaults to. markdown was already in the dependency graph through flutter_markdown; this declares it directly, via melos.yaml. Verified on device as well as in tests: the same message now announces as "You said, Link\ncheck our docs and this now, Just now, Sent". Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…lied The quoted-message announcement built one third-person sentence and dropped the word for "you" into it when the replier was the current user. Every locale had written the template in the third person, so the substitution produced text no native speaker would write: de "Du hat auf deine Nachricht geantwortet" (must be "hast") fr "Vous a répondu au message de …" (must be "avez répondu") it "te ha risposto al tuo messaggio" (oblique subject, wrong verb) Spanish and Catalan mixed a formal subject with an informal possessive, and Korean and Hindi produced "당신님이" and "आप ने" where the pronoun should fuse with the particle. Split the pair into four labels — outgoing/incoming against the quoted message being the reader's own or someone else's — so each locale writes a complete sentence and conjugates it itself. This is the same shape the branch already uses for outgoingMessageLabel / incomingMessageLabel, and the shape Android Compose uses for its own sender descriptions. The English strings are unchanged: "You replied to your message" matches the Android Compose wording for the same case. These labels are new on this branch and unreleased, so the old pair is replaced rather than deprecated. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
StreamMessageItem.semanticsLabel and StreamQuotedMessage.replyMessage are new public parameters, announced in a trailing clause of a bullet under Fixed. Someone scanning the release for new API would not find them there. Give each its own entry under Added, per the changelog policy in STYLE_GUIDE.md, and leave the Fixed bullet to describe the behaviour change it is about.

Went through this against STYLE_GUIDE.md, TESTING.md, Effective Dart, and Flutter 3.47.0's own semantics call sites in flutter/lib/src. Detail is inline; summarising the shape of it here.
The design judgement is good and I'd like to see this land. Composing one phrase per row and having the fragments withdraw is the right call, the quoted-reply attribution and the date-divider header are real wins, and the test suite is the best a11y coverage in the repo. Nothing below is a correctness bug — it's public-API shape and per-build cost, which are the two things that get expensive after release rather than before.
Worth fixing before merge (all mechanical):
outgoingReplyToOwnMessageLabel()is the only zero-arg method among ~15 zero-arg getters inAccessibilityTranslations. It's abstract and implemented in 11 locale files, so it's breaking to flip later._MessageRowSemanticsis documented with///on a private class.- Both changelog entries are PR-description-shaped rather than release-note-shaped.
- Three British spellings (
honour,emphasised,behaviour).
Worth settling in this PR, since they're public surface:
_annotateapplies a label withexplicitChildNodes: truebut leavescontainerdefaulted. Flutter always passescontainer: truefor a labeled composite node — the PR's own test comment documents the consequence, which is that node identity differs between mobile and desktop/web for identical content.semanticsLabel: ''as the "no label" sentinel. Flutter's shape for this issemanticsLabel+ a separateexcludeFromSemanticsbool.StreamMessageStatusLabelsis a public extension onTranslations, a type that isn't exported from the barrel — so callers can use it but can't name its receiver.
One thing I'd want measured: _defaultSemanticsLabel runs a full markdown parse per row per build, regardless of whether semantics are enabled. Message is immutable so it memoises cleanly; I'd just like a number from a long channel on a low-end device first.
On StreamMessageRowLabelScope — I looked for precedent and Flutter has none: it always has the parent wrap children in ExcludeSemantics/BlockSemantics directly rather than signalling through an InheritedWidget (SelectionContainer.disabled is the nearest analogue and it gates behaviour, not semantics). The thing that does justify it here is that a custom footer or content builder can opt out by simply not consulting the scope, which a parent-side wrap would override. That's the load-bearing argument and it isn't in the dartdoc — worth adding, because "why not just ExcludeSemantics?" is the first question a reader will have.
Checked and fine, recording so nobody re-litigates: markdown fidelity against MarkdownBody's default extension set; translation gating reading the same isShowingOriginalTextOf source the bubble does; markdown already transitive via flutter_markdown and added to both melos.yaml and the pubspec; deleted-message goldens unaffected (the golden test pumps StreamMessageDeleted directly); no empty-body double comma (formatEmptyMessage returns a localised fallback); and the upload-progress fix correctly excludes urlPreview from both numerator and denominator while preserving the old hasNonUrlAttachments guard via the attachments.isEmpty early return.

Second pass, narrowed to one question: where does this diverge from how the framework does semantics for its own widgets? Everything below is new — I'm not restating the container: or semanticsLabel: '' items from my previous review, though the first comment here does change my mind on one thing I said there.
Worth saying up front what is framework-shaped, because most of it is: Text.semanticsLabel for the quoted-reply title, Icon.semanticLabel on the delivery indicator, ExcludeSemantics for the gallery overflow badge, Semantics(header: true) on the date divider, Semantics sitting inside the InkWell rather than around it on the attachment tiles, and string-joining label parts with ', ' — the calendar day cell does exactly that. Those are all right.
Four divergences, roughly in order of how much I'd want them changed:
1. StreamMessageRowLabelScope is an ambient signal where the framework uses an explicit parameter. The framework's mechanism for "parent speaks a composed label, descendants go quiet" is Semantics.excludeSemantics (10 call sites, all in pickers and menus). It genuinely doesn't drop in here — the silent parts aren't contiguous with the parts that must stay reachable — but the fix isn't an InheritedWidget either. DefaultStreamMessageItem builds both the content and the footer itself, so it can pass a bool the way Image, GestureDetector, InkResponse and Scrollable all take excludeFromSemantics. Detail inline; it also retracts something I said last round.
2. hideFromRow reimplements ExcludeSemantics.excluding. The framework puts the condition on the wrapper (excluding, blocking, ignoring, visible) rather than branching at the call site. Two-line fix in each of the two files, and it removes the duplication.
3. The date divider announces less than the framework would. StreamTimestamp.semanticsLabel's own dartdoc says its purpose is to give screen readers a clear reference when the visible text is abbreviated; this overrides it to match the abbreviation instead. Flutter's day cell renders a bare day number and announces the full date, with a comment saying why. The clock-time objection in the code comment is fair — the answer is a date-only label at full width, not the abbreviated one.
4. A getter that parses markdown. String.markdownToPlainText reads as a field access, which is a good part of why it landed on a per-build path. Both style guides name this case explicitly.
Plus one comment on an invariant the sending indicator's comment claims but its structure doesn't provide.
One follow-up, explicitly out of scope for this PR — I'd rather not grow it here, but it's the next thing I'd pick up. The row is tappable and long-pressable, and the composed label describes the content without ever saying the row is actionable or what acting on it does. The framework's tools for that are role flags and action hints — calendar_date_picker.dart:1297-1299 sets button: true, selected: ..., enabled: ..., and expansion_tile.dart:676 / expand_icon.dart:192 / modal_barrier.dart:238 use Semantics(onTapHint:, onLongPressHint:) so a reader hears "double tap to open, double tap and hold to show message actions" instead of the generic "activate". This repo already has the vocabulary for it (attachmentPickerOpenTapHint and friends), so it'd be a small follow-up — but it needs new translated strings in 11 locales, which is its own PR.
Generalises the "No Flutter internals in comments" rule to cover Stream's SDKs on other platforms: aligning with stream-chat-swift, -android or -react-native is a real argument for a decision, but it belongs in the PR description rather than in a comment an integrator cannot verify and that goes stale when those SDKs change. Adds the matching repo note on sibling-SDK alignment, so the two halves — check their vocabulary when naming, keep the argument out of the docs — are recorded together. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
It took no arguments yet was the only method among the zero-argument labels on AccessibilityTranslations, which Effective Dart wants as getters. Flipping it now rather than after release, since it is abstract and implemented in every locale. Moves the reason the four reply labels are split by person — a locale that inflects its verb cannot conjugate a name handed to it at runtime — to the class doc, where it reads as guidance for the next implementer instead of the contract of one member. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The divider abbreviates to "Wednesday" or "Aug 26", which leaves a screen reader with no way to tell which Wednesday or which year. It now announces the full date behind the relative day — "Today, August 26, 2026" — since a label may be more explicit than the text it describes. It still avoids StreamTimestamp's default, which would invent a clock time the divider never shows. Drops the MergeSemantics wrapper, which had a single Text descendant and so nothing to merge, and sets container: true to keep the divider its own node. Formats the visible date once instead of once per build. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Replaces StreamMessageRowLabelScope with explicit parameters: StreamMessageContent.excludeTextFromSemantics and StreamMessageFooter.excludeFromSemantics, both passed by the row that builds them. An inherited widget carried "something above already spoke for you", which is not configuration a subtree needs — and a custom footer only behaved correctly if its author knew the scope existed. The exported surface shrinks: the scope is gone, and the status labels move off a public extension on Translations, a type the barrel never exported. StreamMessageItem gains excludeFromSemantics, so leaving a row unlabeled no longer rides in-band on an empty semanticsLabel. Opting out now drops the annotation entirely rather than applying it with an empty label, which restores the node shape from before the row was labelled instead of adding focus stops; container: false is stated at the call site rather than left to the default. The composed label is cached and recomposed only when the message changes or an inherited dependency does. It ran a full markdown parse and a formatter pass on every build of every row, and rows rebuild on new messages, read receipts, typing events and translation toggles. Also moves markdownToPlainText off the public String extension to a private function beside its only caller, and splits the 681-line semantics suite by concern.

Thanks — that was a genuinely useful review, and all 24 threads are addressed in Everything mechanical is done: the getter flip across 12 locales, All four design questions went your way:
Net effect on public API: this review shrank the exported surface. The scope is gone and the status labels moved off a public extension on Three places where following the review turned up something new:
Two things I did not do as asked, both explained in-thread:
Verification: 1337 passing. The 34 golden failures are pre-existing local platform-golden drift — I captured a baseline before touching anything and diffed; the failing set is byte-identical, so nothing here moved a golden. I've left every thread open for you to close, rather than resolving my own. Your follow-up on action hints and role flags sounds right as its own PR — 11 locales of new strings. |

Small one, and take it or leave it — the row now says what it is but never that you can do anything to it. label is the only property set here, so a reader hears "Han Solo said, are we still meeting tomorrow, 3:00 PM" and then nothing about the long press that opens the whole action set.
First, what this is not: I went looking for a missing accessible path and there isn't one. showStreamDialog wraps showGeneralDialog, so the actions modal is a real ModalRoute — Flutter gives it scopesRoute: true, explicitChildNodes: true (routes.dart:2657), a namesRoute announcement off barrierLabel (already wired to modalBarrierDismissLabel), and a ModalBarrier with BlockSemantics to trap focus. stream_modal.dart even adds Semantics(hitTestBehavior: SemanticsHitTestBehavior.opaque) to stop screen-reader taps falling through to the barrier. Every action is reachable and announced today.
So this is discoverability only, and specifically not a case for customSemanticsActions. That's what ReorderableList uses (reorderable_list.dart:1202) because drag has no alternative path at all — here the menu does, and mirroring a context-dependent action list into semantics would just be a second copy to drift out of sync.
What's left is one hint. The framework's tool is SemanticsHintOverrides, used at expansion_tile.dart:676, expand_icon.dart:192 and modal_barrier.dart:238:
Semantics(
label: label,
container: false,
explicitChildNodes: true,
onLongPressHint: context.translations.accessibility.messageActionsLongPressHint,
child: widget.child,
)Deliberately not a committable suggestion, for three reasons:
- It needs the string first.
messageActionsLongPressHintdoesn't exist — it'sAccessibilityTranslationsplus 11 locale files plustranslations_test.dart, same spread this PR already did once. Committing the snippet as-is would not compile. _annotateis the wrong place. It doesn't know whether the row actually has a long press —onLongPressis null for a deleted or still-sending message (:651-656), and announcing "show message actions" on a row that has none is worse than silence. TheInkWellat:651is where that's known, and it's where the framework puts hints (right next to the callback they describe). It's also insidePlatformWidgetBuilder.mobile, which happens to be the correct scope anyway — see below.- Phrasing.
SemanticsHintOverrideswants the outcome, not the gesture:'show message actions', not'double tap and hold to show message actions'— the platform composes the verb. It also asserts on'', so the string can't be blank in any locale.
Honest assessment of the value: SemanticsHintOverrides is effectively an Android/TalkBack channel, so this buys a better announcement there and changes nothing for VoiceOver. Given the actions are already reachable, I'd be happy to see this land as a follow-up rather than grow this PR — I'm noting it here mainly so it's recorded against the code rather than buried in a review body.

Approving on the code. All 24 review threads are addressed — I checked each against d803a29d8 by reading the files rather than the commit messages, and resolved them.
The structural ones came back better than what I asked for. Replacing the scope with excludeTextFromSemantics / excludeFromSemantics shrinks the exported surface instead of growing it, excludeFromSemantics on the row means opting out drops the annotation rather than applying an empty label, and MessageDeliveryStatus documents a real ordering constraint I had written off as an unreachable tidy-up — readsOf compares timestamps only, so a bounced message counts as read by anyone whose lastRead moved past it.
Two things this approval does not cover, both flagged above:
stream_flutter_workflowhas not run ond803a29d8— its last run was on3ac850fad, the pre-review head. The analyzer and the test suite have not seen any of these four commits, and the green checks currently showing are CodeQL and the title/changelog gates. Please don't read this approval as CI verification.- The branch is conflicting with master. Only
packages/stream_chat_flutter/CHANGELOG.mdactually conflicts; everything else auto-merges. Merging master in also re-triggers the workflow, so one push clears both.
The one open thread — a TalkBack onLongPressHint on the row — is a non-blocking follow-up, not a request on this PR.

Description of the pull request
This improves the accessibility for the message listitem.
It adds the sender to the main message, and a 'sender replied to original' for quotes.
It improves the reading of attachments.
It adds header/footer for deleted message, according to the figma design, so the timestamp is also part of the screen reader.
