Split hint from label and expose it via aria-description or aria-describedby by flutter-zl · Pull Request #169157 · flutter/flutter

flutter-zl · 2025-05-20T19:37:23Z

Summary
This PR improves web accessibility in Flutter by separating hint from label in the semantics engine and exposing them via ARIA attributes. The hint is set using aria-description (or aria-describedby as a fallback for browsers that do not support aria-description).

Details
Hint separation:
The hint is exposed via aria-description if supported, or via aria-describedby with a hidden node as a fallback.
Browser compatibility:
Uses feature detection to choose between aria-description and aria-describedby.
Test coverage:
Added/updated tests to verify correct ARIA attribute behavior and fallback logic.

How to verify
All relevant tests pass (semantics_test.dart, semantics_text_test.dart).

Motivation
This change brings Flutter web closer to accessibility best practices and ARIA standards, improving the experience for users of assistive technologies.

Before/After Change
before: https://before-change-hint.web.app/
after: https://after-change-hint.web.app/
after(fallback to aria-describedby): https://after-change-hint-fallback.web.app/

Issues fixed
#162140

Note
Some focus-related tests (e.g., incrementable sends focus events) are failing, but these failures are also present on the main branch and are unrelated to the ARIA label/hint changes in this PR.

    }

    _getEffectiveRepresentation().update(computedLabel);
+    _updateHintDescription(semanticsObject.hint);


somewhere in the doc of this class should mention hint translate to description

chunhtai · 2025-05-22T18:39:24Z

+  void _updateHintDescription(String? hint) {
+    owner.removeAttribute('aria-description');
+    owner.removeAttribute('aria-describedby');
+    if (hint != null && hint.trim().isNotEmpty) {


Suggested change

if (hint != null && hint.trim().isNotEmpty) {

if (hint?.trim().isNotEmpty ?? false) {

ignore this if this doesn't promote the hint to non-null.

it does not promote hint to non-null inside the block, so hint is still of type String?, but _setAriaDescriptionOrDescribedBy expects a non-nullable String.

chunhtai · 2025-05-22T18:40:45Z

+  }
+
+  @visibleForTesting
+  static set supportsAriaDescriptionForTest(bool? value) {


why nullable value?

Passing null resets _supportsAriaDescription to an uninitialized state.
The backing field _supportsAriaDescription is also nullable (bool?).
This setter is used for testing, to override the browser-detected value.

chunhtai · 2025-05-22T18:43:21Z

  /// instead.
  LabelRepresentation preferredRepresentation;

+  String? _describedById;


maybe convert this to a getter so we we don't need to keep them in sync?

String? get _describedById => _describedBySpan?.id

Good idea. Updated.

chunhtai · 2025-05-22T18:44:17Z

+    _describedBySpan!.setAttribute('hidden', '');
+    _describedBySpan!.text = hint;
+    // Attach as a child of the semantics element, not document.body
+    if (_describedBySpan!.isConnected != true) {


I remember a lint would suggest to use ?? instead of equality for checking nullable boolean

Suggested change

if (_describedBySpan!.isConnected != true) {

if (!(_describedBySpan?.isConnected ?? false)) {

chunhtai · 2025-05-22T18:49:22Z

+    _describedBySpan = null;
+    _describedById = null;
+    final String hintId = 'hint-${semanticsObject.id}';
+    domDocument.getElementById(hintId)?.remove();


what is this for?

Updated the logic and remove dead code a bit.

_describedBySpan?.remove() and _describedBySpan = null; removes our aria-describedby span and clears the reference.

+    if (isSafari) {
+      final RegExp safariRegexp = RegExp(r'Version\/([0-9]+)\.([0-9]+)');
+      final RegExpMatch? match = safariRegexp.firstMatch(ui_web.browser.userAgent);
+      if (match != null) {
+        final int majorVersion = int.parse(match.group(1)!);
+        final int minorVersion = int.parse(match.group(2)!);
+        return majorVersion > 17 || (majorVersion == 17 && minorVersion >= 4);
+      }
+      return false;
+    }
+    if (isFirefox) {
+      final RegExp firefoxRegexp = RegExp(r'Firefox\/([0-9]+)');
+      final RegExpMatch? match = firefoxRegexp.firstMatch(ui_web.browser.userAgent);
+      if (match != null) {
+        final int version = int.parse(match.group(1)!);
+        return version >= 119;
+      }
+      return false;
+    }


In the past, we usually put detection logic in the engine/browser_detection.dart file and expose booleans from there.

You could, for example, introduce a isSafari174OrNewer and isFirefox119OrNewer in engine/browser_detection.dart.

Great suggestion. updated.

mdebbar · 2025-05-22T19:04:35Z

+    owner.removeAttribute('aria-description');
+    owner.removeAttribute('aria-describedby');
+    if (hint != null && hint.trim().isNotEmpty) {
+      _setAriaDescriptionOrDescribedBy(hint);
+    }


Can we avoid removing the attributes when not necessary?

Something like this might work:

Suggested change

owner.removeAttribute('aria-description');

owner.removeAttribute('aria-describedby');

if (hint != null && hint.trim().isNotEmpty) {

_setAriaDescriptionOrDescribedBy(hint);

}

if (hint != null && hint.trim().isNotEmpty) {

_setAriaDescriptionOrDescribedBy(hint);

} else {

owner.removeAttribute('aria-description');

owner.removeAttribute('aria-describedby');

}

Great suggestion. updated.

Not sure if this is the right place. I came here from #162140. I was unable to reopen the issue for investigation. I think this is not the right fix.

describedby

is not superseded by

description

In term of accesibility, especially in context of WCAG 2.2, we still need describedby to correctly semantically link the form control to the error message. describedby takes an element's ID, not a String.

@flutter-zl @chunhtai @mdebbar. Please advice how best we can steer this to the correct course.

I believe this PR is correct for its intended scope (hint text). For form validation error linking, I created a specific feature request in #180496.
