Unhandled Except ion: Bad state: Future already completed

[Ice-Coffey]

There seems to be an issue that may be related to ... https://github.com/flutter/flutter/issues/29591 with video player.

But I am getting all of this wonky output in the console for "Bad state: Future already completed" and can't figure out how to fix it.

Here is flutter doctor -v:

[egeysn]

i faced the same error on iOS, i deleted autoplay and auto initialize on ChewieController my problem solved. final networkVideo = networkVideos[pos]; _videoController = VideoPlayerController.network( networkVideos[pos].pitchingVideoUrl) ..initialize();

_chewieController = ChewieController( videoPlayerController: widget._videoPlayerController, looping: false, showControls: false, showControlsOnInitialize: false, aspectRatio: 0.6, errorBuilder: (context, errorMessage) { return Center( child: Text( errorMessage, style: TextStyle(color: Colors.white), ), ); }, );`
