在我的 Android phone 上播放任何视频之前，Flutter 应用程序都会崩溃

Question

我正在尝试使用 flutter 中的这个 video_player 插件，但我无法播放任何视频。即使是他们自己的例子中的那些，也会导致应用程序在我尝试播放时崩溃。我尝试使用不同的小部件，如 futureBuilder，但也没有成功。我搜索了很多，发现了一些关于运行视频的三星问题，但那是荒谬的。任何帮助不胜感激

好的，我发现当我不在“我的 phone 上的调试模式”时它可以工作。也就是说，如果我从计算机上拔下 phone，然后运行单独 phone 上的应用程序，则视频可以正常播放。它对我来说并不完美，但我不会浪费时间。
