我有 key.jks ，我将其添加到 Firebase sha-1和sha-256，然后更新 google-services.json 。我进行了 Flutter 清洁。我在 Firebase 中启用了 Google 的权限。
如何解决此问题。
我想我尝试了所有解决方案...
答案 0 :(得分：0)
从 Google Sign In 抛出的“ApiException 10”是由于在 OAuth2 客户端和应用程序的 API 密钥上未正确配置应用程序签名证书的 SHA-1 导致的。 https://www.google.com/search?q=firebase+auth+apiexception+10
如果您在调试时运行应用，如之前评论中所述，您需要在 Firebase 项目的应用设置中添加 SHA-1 generated from the debug keystore。如果应用在发布时运行也是如此，则应添加发布密钥库中的 SHA-1。
