视频播放器抖动的基本界面

Question

我正在使用该库来实现视频功能。

https://pub.dev/packages/video_player

就目前而言，我已经使它成功了。

但是，接下来，我需要按代码进行播放/暂停或搜索按钮？

我想拥有的只是简单的控制器，例如OS基本播放器，没有可以设计的。

我想有一种无需重新发明轮子就能更轻松地实现接口的方法...

我正确吗？

我在Google周围搜索，但找不到。

您可以使用软件包https://pub.dev/packages/chewie
video_player插件提供了对视频播放的低级访问。 Chewie在引擎盖下使用video_player并将其包装在友好的Material或Cupertino UI中！

示例代码的工作演示
