Question

我正在制作应用程序，其中按下按钮播放资产音频文件，早些时候它可以正常工作，但现在我不知道我的应用程序发生了什么，每当我在我的 phisical android 设备上运行应用程序时，它会生成错误，然后我在 pubspec.yaml 中将包的版本号从 ^0.17.0 更新到 ^0.17.3 但即使那样问题也是一样的，但是如果我从 pubspec.yaml 中删除 audioplayer 包行然后应用程序运行良好，应用程序会发生什么检查，还要检查我的 AndroidManifest.xml 文件代码，错误后给出打击。谢谢

包链接： https://pub.dev/packages/audioplayers

每次运行时都会出现以下错误：
