}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  GsyVideoPlayerController gsyVideoPlayerController = GsyVideoPlayerController(player: GsyVideoPlayerType.ijk);
  late ChewieController chewieController;

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlayer();
  }

  [@override](/user/override)
  void dispose() {
    chewieController.dispose();
    gsyVideoPlayerController.dispose();
    super.dispose();
  }

  // 初始化播放器
  Future<void> initPlayer() async {
    chewieController = ChewieController(
      videoPlayerController: gsyVideoPlayerController,
      looping: false,
      rotateWithSystem: true,
    );
    gsyVideoPlayerController.setLogLevel(LogLevel.logError);
    gsyVideoPlayerController.setNetWorkBuilder(
