Firebase 电子邮件验证 Flutter

Question

我有这段代码可以注册：

      Future<String> signUp({String email, String password}) async {
    try{
      await _firebaseAuth.createUserWithEmailAndPassword(email: email, password: password);

      return "Signed up";
    } on FirebaseAuthException catch(e){
      print("no se puede crear");
      return e.message;
    }
  }

我需要实现来自 firebase 的验证邮件，这已经被问了很多，我在研究时想到了这个，一些代码已被弃用，我很难找到指导：

    Future<String> signUp({String email, String password}) async {
    FirebaseUser user = await _firebaseAuth.createUserWithEmailAndPassword(email: email, password: password);
    try {
      await user.sendEmailVerification();
      return user.uid;
    } catch (e) {
      print("An error occured while trying to send email        verification");
      print(e.message);
    }
  }
  }

但不知道如何实现它，因为它会抛出：

A value of type 'UserCredential' can't be assigned to a variable of type 'FirebaseUser'.

Answer 1

createUserWithEmailAndPassword doesn't return a FirebaseUser object. As you can see from the linked API documentation, it yields a UserCrediental 对象。这就是错误消息试图告诉您的内容 - 您不能将 UserCredential 分配给 FirebaseUser 类型的变量。

如果您想从 UserCredential 中获取 FirebaseUser 对象，您只需使用其 user 属性.

UserCredential credential = await _firebaseAuth.createUserWithEmailAndPassword(email: email, password: password);
FirebaseUser user = credential.user;
