这是我的代码：

import 'package:video_player/video_player.dart';
import 'package:chewie/chewie.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
    home: HomePage(),
    );
  }
}
class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("Video Player"),
      ),
      body: ListView(
        children: <Widget>[
          ChewieList(
            videoPlayerController: VideoPlayerController.asset('assets/videos/soccer.mp4'),
            looping: true,
          ),
          ChewieList(
            videoPlayerController: VideoPlayerController.network(
                'https://file-examples.com/wp-content/uploads/2017/04/file_example_MP4_480_1_5MG.mp4'),
          ),
          /*

          )
           */
        ],
      ),
    );
  }
}




class ChewieList extends StatefulWidget {
  ChewieList({@required this.videoPlayerController,this.looping,Key key,}) : super(key:key);
  final VideoPlayerController videoPlayerController;
  final bool looping;

  @override
  _ChewieListState createState() => _ChewieListState();
}

class _ChewieListState extends State<ChewieList> {
  ChewieController _chewieController;
  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    _chewieController = ChewieController(
        videoPlayerController: widget.videoPlayerController,
        aspectRatio: 16/9,
        autoInitialize: true,
        looping: widget.looping,
        errorBuilder: (context,errMsg){
          return Center(
            child:Column(

              mainAxisAlignment: MainAxisAlignment.center,
              children: <Widget>[
                Icon(Icons.warning,color: Colors.yellowAccent,),
                Text("!خطایی در برقراری ارتباط رخ داده است",style: TextStyle(color: Colors.white),)
              ],
            ),
          );
        }
    );
  }

  @override
  void dispose() {
    // TODO: implement dispose
    super.dispose();
    widget.videoPlayerController.dispose();
    _chewieController.dispose();
  }
  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: EdgeInsets.all(8.0),
      child: Chewie(
        controller: _chewieController,
      ),
    );
  }
}

这让我发疯了！！！！ 请大家帮帮我。

您使用了错误的网址。您发布的网址不是真正的视频网址，而只是一个重定向网址。

尝试：

VideoPlayerController.network('https://file-examples-com.github.io/uploads/2017/04/file_example_MP4_480_1_5MG.mp4'),

（请记住，iOS 模拟器等并不总是支持视频播放。）
