大家好，我需要你的帮助。我有个问题。我只想在横向模式下实现全屏播放器。

并将视频播放器页面留在后退按钮或离开全屏。没有 fullScreenByDefault: true 一切似乎都很好。我可以按后退按钮并返回上一个屏幕。

但是，如果它设置为 true，就会出现问题。按下后退按钮或最小化按钮会进入纵向模式 1 秒钟，然后返回横向，接下来是纵向模式。Next 终于关闭了这个页面。我希望在第一个后退按钮后关闭页面或离开全屏。而且我不知道出了什么问题。提前感谢您的帮助。

  VideoPlayer({this.title, this.url, this.isLive = false});

  final String title;
  final String url;
  final bool isLive;
  @override
  State<StatefulWidget> createState() {
    return _VideoPlayerState();
  }
}

class _VideoPlayerState extends State<VideoPlayer> {
  VideoPlayerController _videoPlayerController1;
  ChewieController _chewieController;

  @override
  void initState() {
    super.initState();

    _videoPlayerController1 = VideoPlayerController.network(
        "https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4");
    _chewieController = ChewieController(
        videoPlayerController: _videoPlayerController1,
        aspectRatio: _videoPlayerController1.value.aspectRatio,
        autoPlay: true,
        looping: true,
        fullScreenByDefault: true,
        isLive: widget.isLive,
        allowedScreenSleep: false,
        deviceOrientationsAfterFullScreen: [
          DeviceOrientation.landscapeRight,
          DeviceOrientation.landscapeLeft,
          DeviceOrientation.portraitUp,
          DeviceOrientation.portraitDown,
        ]
  }


  @override
  Widget build(BuildContext context) {
    SystemChrome.setPreferredOrientations([
      DeviceOrientation.landscapeRight,
      DeviceOrientation.landscapeLeft,
    ]);

    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: SafeArea(
        child: Expanded(
          child: Chewie(
            controller: _chewieController,
          ),
        ),
      ),
    );
  }

  @override
  void dispose() {
    _chewieController.dispose();
    _videoPlayerController1.dispose();

    SystemChrome.setPreferredOrientations([
      DeviceOrientation.landscapeRight,
      DeviceOrientation.landscapeLeft,
      DeviceOrientation.portraitUp,
      DeviceOrientation.portraitDown,
    ]);

    super.dispose();
  }
}

关闭解决方案：将屏幕模式限制为仅横向，不要设置纵横比，设置fullScreenByDefault：false，并将chewie放入Expanded ---- Container（height：size.height，width：size.width）
