Flutter: Flutter Video Player cannot play a video file TWICE [Video controller cannot be used after disposed]~

Question

I'm using Official Flutter Video Player Package for my flutter app, but the displayer is totally black and I also got this error while displaying it on the screen:

E/flutter (10774): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: A VideoPlayerController was used after being disposed.
E/flutter (10774): Once you have called dispose() on a VideoPlayerController, it can no longer be used.

Or Sometimes this:

Here is the code for the player:

late final VideoPlayerController _videoCtrl;
late final Future<void> _videoCtrlInitializationFuture;

  @override
  void initState() {
    super.initState();

    _initVideoCtrl();
  }

  void _initVideoCtrl() {
    _videoCtrl = VideoPlayerController.file(widget.videoFile);
    _videoCtrlInitializationFuture = _videoCtrl.initialize();
  }

  @override
  Widget build(BuildContext context) {
    return FutureBuilder(
      future: _videoCtrlInitializationFuture,
      builder: (BuildContext context, AsyncSnapshot videoCtrlInitSnap) {
        if (videoCtrlInitSnap.connectionState == ConnectionState.done) {
          return AspectRatio(
            aspectRatio: _videoCtrl.value.aspectRatio,
            child: VideoPlayer(_videoCtrl),
          );
        } else {
          return SizedBox.shrink();
        }
      },
    );
  }

  @override
  void dispose() {
    _videoCtrl.dispose();

    super.dispose();
  }

I try to use setState(() {}) and pass a new UniqueKey() to my VideoPlayer widget to create a new video, but the error appears, shows that the controller cannot be used after dispose, although is completely two different widgets.

Answer 1

The bug is caused by the targetSdkVersion in build.gradle file (app level), so I need to add an extra permission

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>

in my manifest.xml file, also set the ios version in podfile to 10 (or above), and done!

Try to edit your initState like below, and tell me the status.

  @override
  void initState() {
    _videoCtrl = VideoEditorController.file(widget.file)
      ..initialize().then((_) => setState(() {}));
    super.initState();
  }

Answer 3

i had a similar problem in my code.

i originally had a controller initalized outside of the a pageview builder and i fixed it by putting the controller further down the widget tree closer to where it was actually being used (i.e. not passing it as an argument to another widget)

I notice then that i would get these explicit debug messages

I/ExoPlayerImpl(13370): Init c2ef839 [ExoPlayerLib/2.18.0] [OP516FL1, NE2213, OnePlus, 31]
I/ExoPlayerImpl(13370): Release ed3786e [ExoPlayerLib/2.18.0] [OP516FL1, NE2213, OnePlus, 31] [goog.exo.core, goog.exo.exoplayer, goog.exo.decoder, goog.exo.datasource, goog.exo.extractor]

so possibly check to see if your getting similar release debug messages when your testing.
