如何在flutter video_player插件上捕获错误？错误为Source error。当发生此错误时，我想显示错误消息。

I/ExoPlayerImpl(31473): Init 98a4284 [ExoPlayerLib/2.9.6] [kenzo, Redmi Note 3, Xiaomi, 23]

我的代码

animeVidBloc.vidCtrl = VideoPlayerController.network(streamurl.src)
          ..initialize().then((_) {
            animeVidBloc.vidCtrl.pause();
            animeVidBloc.cheCtrl = ChewieController(
              videoPlayerController: animeVidBloc.vidCtrl,
              aspectRatio: animeVidBloc.vidCtrl.value.aspectRatio,
              autoPlay: false,
              looping: false,
              allowedScreenSleep: false,
            );
            animeVidBloc.isLoadingData = false;
            animeVidBloc.isLoadingVideo = false;
            animeVidBloc.cheCtrl.pause();
            animeVidBloc.rebuildWidgets(ids: ['body', 'download']);
          });

在.catch之后使用initialize().then无法捕获错误，示例视频https://str09.vidoza.net/x4lfoiywwbzpvjumxbaeidisvq6cmoufczvmicnesasm4zqpyunkofpekfla/v.mp4

您可以将侦听器附加到VidePlayerController对象以捕获控制器的状态。

VideoPlayerController _controller = VideoPlayerController.network(
    "https://str09.vidoza.net/x4lfoiywwbzpvjumxbaeidisvq6cmoufczvmicnesasm4zqpyunkofpekfla/v.mp4")
  ..initialize();

_controller.addListener(() {
  if (_controller.value.hasError) {
    print(_controller.value.errorDescription);
  }
  if (_controller.value.initialized) {}
  if (_controller.value.isBuffering) {}
});
