Using the Chewie Plugin for Flutter Video Playback

{ late VideoPlayerController _videoPlayerController; late ChewieController _chewieController; bool _isLoading = true; bool _hasError = false; @override void initState() { super.initState(); _videoPlayerController = VideoPlayerController.networkUrl( Uri.parse('https://example.com/your-video.mp4'), // Optional headers for secured video access. // httpHeaders: {'Authorization': 'Bearer your_token'}, ); _videoPlayerController.initialize().then((_) { setState(() { _isLoading = false; }); }).catchError((error) { setState(() { _hasError = true; _isLoading = false; }); print('Video initialization error: $error'); }); _chewieController = ChewieController( videoPlayerController: _videoPlayerController, aspectRatio: 16 / 9, autoPlay: false, looping: false, showControls: true, errorBuilder: (context, errorMessage) { return Center( child: Text('Video could not load: $errorMessage'), ); }, materialProgressColors: ChewieProgressColors( playedColor: Colors.red, handleColor: Colors.blue, backgroundColor: Colors.grey, ), // Options like allowFullScreen, allowPlaybackSpeedChanging, placeholder, etc., can be added here. ); } @override Widget build(BuildContext context) { if (_isLoading) { return const Center(child: CircularProgressIndicator()); } if (_hasError) { return const Center(child: Text('Failed to load video.')); } return Scaffold( appBar: AppBar(title: const Text('Chewie Video Player')), body: Center(child: Chewie(controller: _chewieController)), ); } @override void dispose() { _chewieController.dispose(); _videoPlayerController.dispose(); super.dispose(); } } This code sets up the controllers. The ChewieController handles the video and adds controls automatically. It keeps the video in a 16:9 shape and doesn't start playing on its own. Building the Video Player With the controllers ready, the Chewie widget does most of the work. It shows the video with play buttons, a progress bar, and volume controls right out of the box. Place it in the center of your screen, and users can tap to play or pause. If the video isn't loading, check your URL. The widget waits for the video to be ready before showing it. Once it plays, you see the full controls overlaying the video. This setup lets you focus on the app's other parts while Chewie manages the playback details. Customizing Controls Chewie provides multiple customization options on ChewieController : _chewieController = ChewieController( videoPlayerController: _videoPlayerController, aspectRatio: 16 / 9, autoPlay: false, looping: false, showControls: true, materialProgressColors: ChewieProgressColors( playedColor: Colors.red, handleColor: Colors.blue, backgroundColor: Colors.grey, ), ); Now, the progress bar is red for played parts, blue for the handle, and grey for the rest. You can turn off controls by setting showControls to false, or add subtitles if your video has them. Test these changes by running the app. Adjust the colors or settings until they fit your app's style. Handling Errors and Improving Playback Videos can fail to load, so add error handling. In the ChewieController, you can set an errorBuilder: _chewieController = ChewieController( videoPlayerController: _videoPlayerController, aspectRatio: 16 / 9, autoPlay: false, looping: false, errorBuilder: (context, errorMessage) { return Center( child: Text('Video could not load: $errorMessage'), ); }, ); If something goes wrong, this shows a message instead of a blank screen. For better quality, if your video has different sizes, allow users to switch by changing the controller's source. Run the app on a real device to check how it plays. Videos might buffer or skip on slow connections, so you need to test them in different spots. Also, you must tweak the settings based on what you see, and you'll have a smooth player with Chewie.
