一个不同的 google_sign_in 异常：ApiException: 10: , null, null)

Question

当我尝试从我的 flutter 应用程序进行 Google 登录时出现以下错误。

未处理的异常：PlatformException（sign_in_failed，com.google.android.gms.common.api.ApiException：10：）

与堆栈溢出中可用的所有其他问题相比，我在此异常中发现的另一件事是，这里有 2 个 null -

ApiException：10：，null，空）

• 我已将 SHA 添加到 firebase
• 我试过 flutter clean
• 我试图改变 firebase 项目
• 我还尝试使用新的 firebase 项目从头开始重建应用程序。

以下是flutter doctor -v ：

Answer 1

调试案例：- SHA 密钥是这里的主要角色。 如果我们从您的机器生成构建，请确保提供的 SHA 密钥仅属于该设备，我的意思是，在您的机器中生成一个 SHA 密钥并提供该 SHA 密钥

keytool -keystore path-to-debug-or-production-keystore -list -v

Answer 2

对于一个以前运行良好的应用程序，我为此努力了好几个小时。

我能找到的所有 SHA-1 密钥（调试、发布、播放签名）都已添加到 Firebase。

在“尝试了一切”之后，我决定也在Google Cloud Console中彻底检查它们。 事实证明，他们都已经在那里了。

但是-其中一个已添加到错误的项目中，从该项目中删除并将其添加到正确的项目后。 谷歌登录立即重新开始工作。

为什么在多年将 SHA-1 密钥用于错误的项目并且在 Play 商店中看似正常工作的应用程序之后，这突然成为一个问题，这让我无法理解。 但这可能会帮助其他人突然ApiException: 10: , null, null 。
