如何使用 (player_video) 包播放多个视频

Question

我为我的 应用程序 创建了这个视频播放器，它可以播放资产中的视频。因为，它是由 (video_player) 包制作的我想我只能用它播放一个视频但我想要 3-4 个视频 待播放。我怎样才能做到这一点？是可能还是不行...帮帮我！此外，我还想将视频设为 10 秒 backward 和 forward 的选项，同时按下它的两侧。 感谢您的帮助！

    controller = VideoPlayerController.asset(widget.pathh!);
    futureController = controller.initialize();

    controller.setLooping(true);
    controller.setVolume(25.0);
    super.initState();
  }

  @override
