flutter用chewie播放flv格式的视频示例

以下是一个使用 Chewie 播放 FLV 格式视频的 Flutter 示例代码：

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

class FLVPlayer extends StatefulWidget {
  final String videoUrl;

  FLVPlayer({@required this.videoUrl});

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

class _FLVPlayerState extends State<FLVPlayer> {
  VideoPlayerController _videoPlayerController;
  ChewieController _chewieController;

  @override
  void initState() {
    super.initState();
    _videoPlayerController = VideoPlayerController.network(widget.videoUrl);
    _chewieController = ChewieController(
      videoPlayerController: _videoPlayerController,
      aspectRatio: 16 / 9,
      autoPlay: true,
      looping: true,
    );
  }

  @override
  void dispose() {
    _videoPlayerController.dispose();
    _chewieController.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('FLV Player'),
      ),
      body: Center(
        child: Chewie(
          controller: _chewieController,
        ),
      ),
    );
  }
}

你可以在 `FLVPlayer` 类中传入一个 FLV 格式视频的 URL，然后使用 `Chewie` 组件来播放视频。注意，你需要在 `initState` 方法中初始化 `VideoPlayerController` 和 `ChewieController`，并在 `dispose` 方法中释放资源。
