主要用到了 VideoPlay(VideoPlayController)

VideoPlayerController controller;  bool initialized = false;  @override  void initState() {    super.initState();    //初始化播放控件    controller= VideoPlayerController.file(widget.videoFile);   //视频初始化    controller.initialize().then((value){        initialized=true;        //刷新页面显示播放器        setState(() {        });    });  }  @override  Widget build(BuildContext context) {    if (initialized) {      final Size size = controller.value.size;      return SizedBox(width:100.0,child:AspectRatio(          aspectRatio: size.width / size.height,          child: VideoPlayer(controller),        ));    } else {      return new Container();    }  }

前面需要导入

import 'package:video_player/video_player.dart';import 'package:dio/dio.dart';
