我有一个Flutter应用程序，该应用程序使用Firebase身份验证和Google登录。在准备将其用于初始测试版本以在调试模式之外尝试之前，该应用程序运行良好。从那以后，当尝试在Android Studio中调试运行时，该应用程序在启动时立即崩溃。
Flutter医生显示了此信息

我已经找到了一些答案，可以尝试从Google Play控制台和firebase对齐SHA键以及更改程序包版本，但是我没有找到任何有效的组合。
“运行”控制台仅显示：
Launching lib/main.dart on Pixel in debug mode...
Initializing gradle...
Resolving dependencies...
Running Gradle task 'assembleDebug'...
Built build/app/outputs/apk/debug/app-debug.apk.
我也在日志中得到了这个

还有其他人遇到过这样的事情吗？我一直在努力找回我的应用程序，因为它之前运行良好，但到目前为止没有任何效果。希望有帮助！
