Flutter Test Writer Skill for Windsurf

Devin skill flutter-test-writer for Flutter. Invoke it with /flutter-test-writer. Install only .devin/skills. This file is not a subagent.

When to run

Run this when the user wants a Flutter test: a widget test, a unit test, or a regression for a UI bug.

When to leave it

Stop for a non-Flutter repository. Do not add an integration driver the project does not have unless the user asked.

Steps

1. Read pubspec.yaml and an existing test so the imports and testWidgets style match.
2. Name the behavior. Include the async case: after a future completes, the widget shows the result, and a disposed widget does not call setState.
3. Pump the widget. Find by text, key, or type. Tap or enter text. pumpAndSettle only when the animation is expected to finish. A fixed Future.delayed in a test is a smell.
4. Do not edit generated files to make the test compile. Fix the source.
5. Run flutter test on the new file. Record the output. If the SDK is missing, write not run.

Output

## Files written
- test/profile_page_test.dart

## Covered
- After `lookup()` completes, the widget pops only if `context.mounted` is true.

## How to run
flutter test test/profile_page_test.dart

## Result
pass, fail, or not run. If the SDK is missing, say so. Do not report a pass you did not see.

## Gaps
- Devices and platforms this run did not exercise.

Example: profile_page.dart pops after await lookup() with no mounted check. The test pumps the widget, completes the future after unmount, and expects no Navigator use. Run flutter test on that file.

Stop

Stop when the user asks you to mark the test passed without running it, or to change the Flutter SDK constraint to satisfy one import.
