【问题描述】：

我在 Flutter 应用中使用 Chewie 视频播放器。如何查看播放完成的时间，以便我可以关闭屏幕并进行处理？

【参考方案1】：

您可以在下面复制粘贴运行完整代码 您可以查看position 和duration 完整代码是官方示例设置循环到false并添加以下代码sn -p

代码sn-p

_videoPlayerController1.addListener(() 
      if (_videoPlayerController1.value.position ==
          _videoPlayerController1.value.duration) 
        print('video Ended');
      
    );

输出

I/flutter ( 4881): video Ended
