flutter chewie 视频播放

1.下载插件

chewie: ^0.9.8+1
video_player: ^0.10.10

2.在使用页面引入

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

 3.定义

  VideoPlayerController videoPlayerController;
  ChewieController chewieController;

4.初始化在 initState() 中

    videoPlayerController = VideoPlayerController.network(
        'https://www.runoob.com/try/demo_source/mov_bbb.mp4');
    
    videoPlayerController.initialize(); // 初始化
    
    chewieController = ChewieController(
      videoPlayerController: videoPlayerController,
      aspectRatio: 3 / 2, //宽高比
      autoPlay: false, //自动播放
      looping: false, //循环播放
    );

5.在 dispose()中卸载

videoPlayerController.dispose();

6.使用

Container(
                    height: 200,
                    child: Chewie(
                        controller: ChewieController(
                            videoPlayerController:videoPlayerController
                        )
                    ),
                  )

6.成功啦

如果想获取请求的视频链接，那就在builder里初始化，这样的话就可以删掉initState() 中的初始化设置，就是第三步不要

   // 判断视频是否存在
    if(data["videoUrl"] != null ) {
      videoPlayerController = VideoPlayerController.network(
          data["videoUrl"]
      );
      videoPlayerController.initialize(); // 初始化

      chewieController = ChewieController(
        videoPlayerController: videoPlayerController,
//        aspectRatio: 3 / 2, //宽高比
        autoPlay: false, //自动播放
        looping: false, //循环播放
      );
    }
