Part of #182636

Summary

Remove the semantics_tester.dart cross-import from material_button_test.dart.

What changed

Replaced the deprecated SemanticsTester/TestSemantics assertions in the MaterialButton semantics test with tester.getSemantics(...) and matchesSemantics(...)
Kept the semantic size verification for the enabled and disabled button states
Removed the ../widgets/semantics_tester.dart import

Testing

../../bin/flutter analyze test/material/material_button_test.dart
../../bin/flutter test test/material/material_button_test.dart

Code Review

This pull request refactors the semantics tests for MaterialButton to use the matchesSemantics matcher and tester.getSemantics API, replacing the deprecated SemanticsTester. A review comment identifies that the updated assertions for the disabled button state are less rigorous than the original implementation and suggests explicitly verifying that the button is disabled and lacks a tap action to maintain test coverage.

Sanaullah49 · 2026-04-28T10:53:16Z

The disabled MaterialButton semantics check on the PR branch now explicitly verifies that isEnabled is false and the tap action is absent. Verified the changed test locally with ./bin/flutter test packages/flutter/test/material/material_button_test.dart --plain-name "Disabled MaterialButton has same semantic size as enabled and exposes disabled semantics".

        ),
      );

+      final SemanticsNode semantics = tester.getSemantics(find.byType(MaterialButton));


Nit: I find it somewhat strange that the previous tester.getSemantics is done inline inside of expect but this one isn't. A very minor nit though :)

This conversion looks good, left some comments

-      const expectedButtonSize = Rect.fromLTRB(0.0, 0.0, 116.0, 48.0);
-      // Button is in center of screen
-      final expectedButtonTransform = Matrix4.identity()


can we keep the check for transform?

I think we can directly compare SemanticsNode.transform

Kept — expect(enabledSemantics.transform, expectedButtonTransform) and the same for disabledSemantics are now in the test (lines 678 and 708). The expectedButtonTransform constant is preserved.

-          TestSemantics.fullScreen.height / 2 - expectedButtonSize.height / 2,
-        );
+      final SemanticsHandle handle = tester.ensureSemantics();


This is not needed

Sanaullah49 · 2026-05-05T05:25:18Z

Thanks @justinmc and @chunhtai! Addressed all the feedback:

Replaced SemanticsHandle handle + manual handle.dispose() with addTearDown(tester.ensureSemantics().dispose)
Restored the transform check via SemanticsNode.transform as requested by @chunhtai
Extracted the enabled-button semantics into a variable for consistency with the disabled-button section

@chunhtai

…tent semantics variables - Replace manual SemanticsHandle + dispose with addTearDown pattern - Restore expectedButtonTransform check via SemanticsNode.transform as requested by @chunhtai - Extract enabled button semantics into a variable for consistency with the disabled button section

I don't think this is needed?

Done in c4bb886 — you're right, tester.getSemantics reads debugSemantics directly via SemanticsController.find (no enable needed), and filled_button_test.dart follows the same pattern. Removed the addTearDown line.

tester.getSemantics reads debugSemantics directly via SemanticsController.find, so ensureSemantics is not required for this test. Matches the pattern used in filled_button_test.dart.

TestSemantics.fullScreen is defined in semantics_tester.dart, which this PR removes the import for. Replace the reference with the literal 400.0/300.0 (half of the 800x600 test screen) so the test compiles without the semantics_tester import.

Sanaullah49 · 2026-05-21T10:10:21Z

Pushed a small fix for the failing run: removed the obvious local type annotations flagged by analyze and adjusted the transform expectation to include the root semantics scale. Local checks pass: ./bin/dart analyze packages/flutter/test/material/material_button_test.dart and ./bin/flutter test packages/flutter/test/material/material_button_test.dart --plain-name "Disabled MaterialButton has same semantic size as enabled and exposes disabled semantics".

This pull request is not mergeable in its current state, likely because of a merge conflict. Pre-submit CI jobs were not triggered. Pushing a new commit to this branch that resolves the issue will result in pre-submit jobs being scheduled.
