@nandawperdana Can you provide sample code for that?

@nandawperdana Can you provide sample code for that?

So basically I set the ID for every BetterPlayerController attached to video model that will be shown and played on screen. Like this:

class VideoServiceState {
  BetterPlayerController? playerController;
  StreamController<BetterPlayerEvent> playerEvent;
  VideoModel? videoModel;
  dynamic Function(BetterPlayerEvent) eventListener;

  VideoServiceState(this.playerController, this.progressController,
      this.playerEvent, this.videoModel, this.eventListener);
}

class VideoService {
  final Map<int, VideoServiceState> _states = {};
}

and use the _states to control the video based on ID. Let say for playing the video:

  Future<void> play(int id) async {
    try {
      await _states[id]?.playerController?.play();
    } catch (e, s) {}
  }

and, dispose the controller for specific video ID, like this:

  void dispose(int id) {
    try {
      final controller = _states[id]?.playerController;
      final isPlaying = controller?.isPlaying() ?? false;
      if (isPlaying) controller?.pause();
      controller?.dispose();
      _states[id]?.progressController.close();
      _states[id]?.playerEvent.close();
      _states.remove(id);
    } catch (e) {}
  }

actually, the error shown even before the video played or started, is there any background processes causing error?
