java - 未处理的异常 : PlatformException (sign_in_failed, com.google.android.gms.common.api.ApiException : 10: , null, null) - 在一个系统中运行良好

Question

我正在使用 Flutter 中的平台 channel 开发蓝牙应用程序(使用 Java)。但是，当我尝试使用 google-sign in( google_sign_in: ^4.5.6 ) 登录时，我遇到了错误。
我可以登录详细信息，但我无法移动到更多页面......
实际上，它在我的办公系统中工作，但是当我复制项目并在另一个项目中运行时，它给出了错误......任何人都可以帮忙

[ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null, null) apiException:10 表示很可能是由于 SHA-1 或 SHA-256 设置不正确。既然您说它在办公室工作，它可能与您现在使用的环境不同，您应该添加这些 key 。这也假设您正在运行调试版本，因此添加您的调试 SHA-1 key 。
