[video_player] Ignore late position updates after disposal - #12971
auto-submit[bot] merged 5 commits into
Conversation
A platform seek can finish after the controller has been disposed, including the seek triggered by a playback-completed event. Guard the shared position update before writing the notifier, and cover both pending seek paths with regression tests.

Code Review
This pull request updates the video_player package to version 2.14.1, introducing a fix that ignores late position updates after a VideoPlayerController is disposed. It includes new tests to verify this behavior using a simulated pending seek on a fake platform. The review feedback suggests resetting the shared seekCompleter to null using addTearDown in the new tests to prevent state leakage between tests.

Code Review
This pull request updates the video_player package to version 2.14.1, introducing a check in _updatePosition to return early if the controller is disposed, which prevents late position updates. New tests are added to verify that pending seek and completion seek results are ignored after disposal. The review feedback suggests resetting the shared fakeVideoPlayerPlatform.seekCompleter to null using addTearDown in the new tests to prevent potential side effects on subsequent tests.

A platform seek can finish after
VideoPlayerController.dispose(), causing_updatePositionto write to the disposed notifier and throw. This also happens in the controller's ownVideoEventType.completedpause/seek chain, without the caller invoking a method after disposal.Checks
_isDisposedat the shared position-update boundary. Adds regressions for an explicit pending seek and the pending seek from a playback-completed event. Both tests fail on the unmodified controller and pass with the guard. The patch updates the package to 2.14.1 and incorporates the existingNEXTchangelog entry as required by the release instructions.Fixes flutter/flutter#193147
Validation with Flutter 3.44.9 / Dart 3.12.2:
dart analyze --fatal-infosfor the package and example: no issues.publish-check: passed after committing the four-file patch.git diff --check: passed.Repository-wide
validatecould not complete in the sparse checkout because the root README references packages outside the checkout (animations). Native/integration tests were not run; this change is limited to the Dart controller.No public API or dartdoc changes are needed.
