在Android手机上效果 在IPhone手机上效果 我们可以看到当在iPhone手机上进行全屏播放的时候屏幕并没有旋转过来查阅了很多资料都没能很好的解决后来只能自己在iOS端用原生写了个播放器利用FLutter嵌入原生的开发模式来适配全屏播放
最终效果如下 如果有什么好的方法解决这个在iOS不能旋转屏幕的想法的欢迎在下方留言。。。。
下面贴出代码
1、FLutter视频播放器采用的是chewie
封装的播放器代码如下
import dart:io;
import package:chewie/chewie.dart;
import package:flutter/material.dart;
// ignore: depend_on_referenced_packages
import package:video_player/video_player.dart;class VideoPlayerWidget extends StatefulWidget {final String videoUrl;final bool fullScreenByDefault;const VideoPlayerWidget({super.key,required this.videoUrl,this.fullScreenByDefault false,});overrideStateVideoPlayerWidget createState() _VideoPlayerWidgetState();
}class _VideoPlayerWidgetState extends StateVideoPlayerWidget {late VideoPlayerController _videoPlayerController;ChewieController? _chewieController;int? bufferDelay;overridevoid initState() {super.initState();initializePlayer();}overridevoid dispose() {_videoPlayerController.dispose();_chewieController?.dispose();super.dispose();}ListString srcs [https://assets.mixkit.co/videos/preview/mixkit-spinning-around-the-earth-29351-large.mp4,https://assets.mixkit.co/videos/preview/mixkit-daytime-city-traffic-aerial-view-56-large.mp4,https://assets.mixkit.co/videos/preview/mixkit-a-girl-blowing-a-bubble-gum-at-an-amusement-park-1226-large.mp4];Futurevoid initializePlayer() async {//判断是本地视频还是网络请求下来的视频if (widget.videoUrl.contains(http)) {_videoPlayerController VideoPlayerController.networkUrl(Uri.parse(widget.videoUrl));} else {_videoPlayerController VideoPlayerController.file(File(widget.videoUrl));}await Future.wait([_videoPlayerController.initialize(),]);_createChewieController();setState(() {});}void _createChewieController() {_chewieController ChewieController(videoPlayerController: _videoPlayerController,autoPlay: true,hideControlsTimer: const Duration(seconds: 10),allowPlaybackSpeedChanging: false,fullScreenByDefault: widget.fullScreenByDefault,);}overrideWidget build(BuildContext context) {return Container(color: const Color.fromRGBO(28, 34, 47, 1),width: MediaQuery.of(context).size.width - 20,height: 300,child: Center(child: _chewieController ! null _chewieController!.videoPlayerController.value.isInitialized? Chewie(controller: _chewieController!,): const Column(mainAxisAlignment: MainAxisAlignment.center,children: [CircularProgressIndicator(),SizedBox(height: 20),Text(Loading,style: TextStyle(color: Colors.white,),),],),),);}
}
如果碰到Video Player UnimplementedError: init() has not been implemented的错误关闭App重新运行Flutter run就行了 视频播放链接https://assets.mixkit.co/videos/preview/mixkit-spinning-around-the-earth-29351-large.mp4
2、使用的时候区分了Android端和iOS端
body: Center(child: ElevatedButton(onPressed: () {showDialog(context: context,builder: (context) {return Dialog(insetPadding: const EdgeInsets.only(left: 0),child: Platform.isAndroid? const VideoPlayerWidget(videoUrl: videoUrl,) //Android视频播放器: SizedBox(width: MediaQuery.of(context).size.width,height: MediaQuery.of(context).size.width * 9 / 16,child: const UiKitView(viewType:plugins.flutter.io/custom_platform_view_plugin,creationParams: {videoUrl: videoUrl,},creationParamsCodec: StandardMessageCodec(),),), //iOS视频播放器);},);},child: const Text(点击播放视频),),),3、iOS端的代码用OC实现的只贴出文件目录需要的同学可以直接去GitHub上下载原代码 因为写视频播放器的时候用到了Masonry三方所有用户需要再Podfile里面加入pod Masonry然后cd到Runner目录下运行pod install安装Masonry
4、最后在AppDelegate.m里面注册一下
[FlutterViewRegistran registerWithRegistry:self];
5、Git代码传送门
喜欢的同学欢迎帮忙点个star 简书传送门
