Re-enable flame.test in customer_testing once flame-engine/flame#4125 lands #194883

flutter/tests#508 temporarily disabled registry/flame.test to unblock Linux customer_testing on flutter/flutter.

material_ui 1.8.0 (published to pub.dev from flutter/packages#13321, including flutter/packages#13161) enabled route-transition raster snapshotting (allowSnapshotting = true) in FadeForwardsPageTransitionsBuilder on Android, matching ZoomPageTransitionsBuilder.

Because registry/flame.test checks out flame-engine/flame (which has no pubspec.lock and declares material_ui: any) and runs flutter packages get (update=.), every customer_testing run after material_ui 1.8.0 was published resolved 1.8.0 live from pub.dev and failed in game_widget_lifecycle_test.dart:

Expected: ['onGameResize', 'onLoad', 'onMount', 'update', 'render', 'update', 'render', 'update', 'onRemove', 'onDispose']
  Actual: ['onGameResize', 'onLoad', 'onMount', 'update', 'render', 'update', 'update', 'onRemove', 'onDispose']
   Which: at location [6] is 'update' instead of 'render'

In that test, tester.tap(find.text('Play')) pumps a second frame 16ms into the /game route transition; SnapshotWidget now reuses the raster snapshot captured on the first transition frame instead of calling GameRenderBox.paint a second time.

To close this issue:

• Land Temporarily disable flame.test for material_ui 1.8.0 tests#508 to temporarily disable registry/flame.test.
• Land Bump customer_testing to temporarily disable flame.test #194886 to roll dev/customer_testing/tests.version in flutter/flutter.
• Remove the Linux customer_testing suppression on the Flutter Dashboard once Bump customer_testing to temporarily disable flame.test #194886 lands.
• Land test: Update game_widget_lifecycle_test for material_ui 1.8.0 flame-engine/flame#4125 to update game_widget_lifecycle_test.dart for material_ui 1.8.0.
• Re-enable registry/flame.test in flutter/tests (Re-enable flame.test with fix for material_ui 1.8.0 tests#509) pinned to the new flame-engine/flame commit (69b0968f97e3fdc07b3f19a44ba0df5a01a53d04).
• Roll dev/customer_testing/tests.version in flutter/flutter (Bump customer_testing to re-enable flame.test #194968) to pick up the re-enabled flame.test.
