将应用程序图标更改为flutter_launcher_icons后，在运行flutter run和flutter build apk后开始出现此问题:
flutter build apk -debug

(它是一个生成的文件，位于/Users/pitol/.gradle/caches/transforms-3/dfcbd5820ba82f60df3a20d93f4b43e6/transformed/core-1.8.0/res/values/values.xml)
try 运行flutter doctor -v次，解决了所有依赖项，更新了Android Studio，更新了Java，但当我try 构建Android应用程序时仍然收到这个错误(Doctor-v命令没有显示错误)；
已经在Mac和Windows上试过了，它显示了相同的错误；
我还try 创建了一个新的Flutter 翼项目，并成功地构建了，所以问题在项目中，而不是在框架中；
