Flutter视频播放器chenge视频源动态

Question

如何使用默认的视频播放器实现动态更改Flutter'https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4'中的视频？

void initState() {
    // Create and store the VideoPlayerController. The VideoPlayerController
    // offers several different constructors to play videos from assets, files,
    // or the internet.
    _controller = VideoPlayerController.network(
      'https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4',
    );

    // Initialize the controller and store the Future for later use.
    _initializeVideoPlayerFuture = _controller.initialize();

    // Use the controller to loop the video.
    _controller.setLooping(true);

    super.initState();
  }

Answer 1

您是否尝试过，

void initState() {
    // Initialize the controller and store the Future for later use.
    _initializeVideoPlayerFuture = _controller.initialize();
setUpVideo('https://flutter.github.io/assets-for-api-docs/assets/videos/butterfly.mp4');
    super.initState();
  }

setUpVideo(String url){
    // Create and store the VideoPlayerController. The VideoPlayerController
    // offers several different constructors to play videos from assets, files,
    // or the internet.
    _controller = VideoPlayerController.network(
      url,
    );

    // Use the controller to loop the video.
    _controller.setLooping(true);

}

现在在代码调用setState中的任何位置，

setState(() {
   setUpVideo('another_url');
});
