FirebaseUser user = (await auth.signInWithXXX(uid)).user; // is there any method like this

推荐答案

Firebase 客户端 SDK 中没有 API 来根据 UID 获取用户信息，因为这可能会引起安全问题.

There is no API in the Firebase client-side SDKs to get user information based on a UID, as this could potentially be a security concern.

如果您需要此信息，您可以实现自己的使用 Firebase Admin SDK 的服务器(确实具有此功能)，或者您可以将用户信息存储在辅助数据库中，例如Firebase 自己的实时数据库或 Cloud Firestore.然后，您可以从应用程序的其余部分查询此数据库，并使用数据库的服务器端安全规则来保护访问以满足您的需求.

If you need this information, you can either implement your own server that uses the Firebase Admin SDKs (which do have this functionality), or you can store user information in a secondary database, such as Firebase's own Realtime Database or Cloud Firestore. Then you can query this database from the rest of your application, and secure access to fit your needs with the database's server-side security rules.
