firebase - Flutter 应用无法使用 google 登录

Question

编辑:-有趣的是，我的练习应用程序具有完全相同的代码，显示相同的控制台日志，但工作绝对正常，但主应用程序(此应用程序)不起作用。
我的应用程序在几个小时前运行良好，但由于早上登录失败并出现此错误

E/flutter (24958): [ERROR:flutter/lib/ui/ui_dart_state.cc(166)] Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)

Stackoverflow 说要更改 com.android.tools.build:gradle。这是怎么突然发生的，我什至连代码都没碰过。
安慰:
