如何使视频缩略图抖动？

为他人。使用视频播放器插件作为缩略图。这对那些库非常有效，并且也适用于ios。只需像创建item一样创建statefullWidget（如果要在列表中显示，请将该控件用作item）。请参见以下示例。

class _VideoItemState extends State<VideoItem> {VideoPlayerController _controller;@overridevoid initState() {super.initState();_controller = VideoPlayerController.network(widget.video.file.path)  ..initialize().then((_) {    setState(() {});  //when your thumbnail will show.  });}@overridevoid dispose() {super.dispose();_controller.dispose();}@overrideWidget build(BuildContext context) {return ListTile(  leading: _controller.value.initialized      ? Container(          width: 100.0,          height: 56.0,          child: VideoPlayer(_controller),        )      : CircularProgressIndicator(),  title: Text(widget.video.file.path.split('/').last),  onTap: () {    Navigator.push(      context,      MaterialPageRoute(        builder: (context) => VideoPlayerPage(videoUrl: widget.video.file.path),      ),    );  },); }}
