class LocalVideoStoryItem extends StatefulWidget {
  final String videoPath;
  final Duration duration;
  final Widget? caption;

  const LocalVideoStoryItem({
    required this.videoPath,
    required this.duration,
    this.caption,
    Key? key,
  }) : super(key: key);

  @override
  _LocalVideoStoryItemState createState() => _LocalVideoStoryItemState();
}

class _LocalVideoStoryItemState extends State<LocalVideoStoryItem> {
  late VideoPlayerController _controller;
  late Future<void> _initializeVideoPlayerFuture;
  GetStorage localMemory = GetStorage();

  @override
  void initState() {
    super.initState();
    _controller = VideoPlayerController.asset(widget.videoPath);
    _initializeVideoPlayerFuture = _controller.initialize().then((_) {
      setState(() {
        _controller.play();
      });
    });
    _controller.setLooping(true);
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }

  @override

              return AspectRatio(
                aspectRatio: _controller.value.aspectRatio,
                child: VideoPlayer(_controller),
              );
