【问题描述】：
在我在 pubspec.yaml 文件中添加 'firebase_auth: ^0.15.5+3' 之前，我的 Flutter 应用程序运行良好。我对这个错误感到震惊：
Launching lib\main.dart on BLN L22 in debug mode...
[!] Your app isn't using AndroidX.
To avoid potential build failures, you can quickly migrate your app by following the steps on (some google link here).
Running Gradle task 'assembleDebug'...

AndroidX incompatibilities may have caused this build to fail. Please migrate your app to AndroidX. See (some google link here)
Finished with error: Gradle task assembleDebug failed with exit code 1
我也尝试将 minSdkVersion 从 16 更改为 21，但没有成功。
