Flutter 闪屏视频播放器

Question

I am trying to create a background video splash screen for my app. Currently, I am achieving a blank screen by running this code.

 void main() => runApp(WalkThrough());

class WalkThrough extends StatefulWidget {
  @override
  _WalkThroughState createState() => _WalkThroughState();
}

class _WalkThroughState extends State<WalkThrough> {
  VideoPlayerController _controller;

  @override
  void initState() {
    super.initState();
    // Pointing the video controller to our local asset.
    _controller = VideoPlayerController.asset('assets/video.mp4')
      ..initialize().then((_) {
        // Once the video has been loaded we play the video and set looping to true.
        _controller.play();
        _controller.setLooping(true);
        _controller.setVolume(0.0);
        _controller.play();
        // Ensure the first frame is shown after the video is initialized.
        setState(() {});
      });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Stack(
        children: <Widget>[

I suspect the problem may be here and have based my research off this Full screen video background in Flutter on Login as I am trying to achieve a similar result.

          SizedBox.expand(
            child: FittedBox(
              // If your background video doesn't look right, try changing the BoxFit property.
              // BoxFit.fill created the look I was going for.
              fit: BoxFit.fill,
              child: SizedBox(
                width: _controller.value.size?.width ?? 0,
                height: _controller.value.size?.height ?? 0,
                child: VideoPlayer(_controller),
              ),
            ),
          ),

我认为视频播放器包在 Ios 模拟器中显示视频有问题。我遇到了同样的问题并搜索它并找到了这个 issue in Github .直到现在这个问题是开放的。我在真实设备上测试了视频播放器，没有任何问题。
