  "message": "[flutter_tools] Fix widget_preview unawaited async write race condition (#187177)\n\nThis PR resolves a deterministic race condition in\n`preview_detector_test_utils.dart`. The test helper `changeOperation`\ncallback is converted to support and properly `await` `FutureOr\u003cvoid\u003e`,\nensuring asynchronous package-configuration writes are fully completed\nbefore `tearDown` deletes the temporary workspace directories. This\nresolves flakiness and unhandled exceptions under high load in both\nLinux and Mac shards.\n\nFixes https://github.com/flutter/flutter/issues/186136",
