chewie库将用于播放m3u8文件

添加依赖关系

dependencies:
  chewie: ^0.9.10

代码段：

import 'package:flutter/material.dart';
import 'package:chewie/chewie.dart';
import 'package:video_player/video_player.dart';

void main() {
  runApp(MaterialApp(home: MyApp()));
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final videoPlayerController = VideoPlayerController.network(
      'url.m3u8');
  ChewieController chewieController;

  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    chewieController = ChewieController(
      videoPlayerController: videoPlayerController,
      aspectRatio: 3 / 2,
      autoPlay: true,
      looping: true,
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text("Sample App"),
        ),
        body: Container(
          child: Chewie(controller: chewieController),
        ));
  }
}

yoyo播放器是最好的选择，但这个包不支持你的项目，你可以使用这个包，我改变了yaml和更新这个包，为更新Flutter，

yoyo_player:
    git:
      url: https://github.com/AmiirTorabii/yoyo_player_update

它为我工作：）

YoYo player是一个很好的选择。
1.添加依赖关系：
yoyo_player: #latest
1.在任何你想要的地方使用：

YoYoPlayer(
       aspectRatio: 16 / 9,
       url:  "",
       videoStyle: VideoStyle(),
       videoLoadingStyle: VideoLoadingStyle(),
  ),
