Firebase Android - 在Kotlin中使用电子邮件和密码创建用户

Question

我正在尝试向Firebase和Kotlin进行注册.看一下docs,我看到了Java中的所有例子.因此,当我尝试在Kotlin中实施时,我无法使其工作.

在Java中应该是这样的:

// [START create_user_with_email]
        mAuth.createUserWithEmailAndPassword(email, password)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                            FirebaseUser user = mAuth.getCurrentUser();

                        } else {
                            // If sign in fails, display a message to the user.
                            ......
                        }

                        // [START_EXCLUDE]
                        .......
                        // [END_EXCLUDE]
                    }
                });
        // [END create_user_with_email]

但是,当我尝试在kotlin中实现这样:

// [START create_user_with_email]
        mAuth.createUserWithEmailAndPassword(email, password)
                .addOnCompleteListener(this, OnCompleteListener<AuthResult> { task ->
                    if (task.isSuccessful) {
                        // Sign in success, update UI with the signed-in user's information                        
                        val user = mAuth.currentUser                       
                    } else {
                        ......
                    }

                    // [START_EXCLUDE]
                            .....
                    // [END_EXCLUDE]
                })
        // [END create_user_with_email]

但是这个,给我一个错误:

我不知道如何解决它.

我已通过以下方式使用电子邮件和密码实施Firebase注册,它可以正常工作:

this.firebaseAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener { task: Task<AuthResult> ->
    if (task.isSuccessful) {
        //Registration OK
        val firebaseUser = this.firebaseAuth.currentUser!!
    } else {
        //Registration error 
    }
}
