Question 108568 in Flutter Question posted in
The official Flutter documentation can be found here.

Flutter – Is it possible to create user with email and password and add username(display name) immediately?

When you create user using firebase auth on flutter, you able to set email and password while creating user. I also need to set display name while creating user, but i found only way to set display name after creating user.

I used code like this

FirebaseAuth.instance.
    createUserWithEmailAndPassword(
  email: eMail.text.trim(),
  password: passWord.text.trim(),
)
    .then((uC){
  uC.user!
      .updateDisplayName(userName.text.trim());
}

But this isn’t what I need

    yes, you can use fireStore to add user detail to firebase after SignUp is successful.

    Future<bool> signUp(String name,String email,String phone,String password,BuildContext context) async {
    try{

      //loading dialog starts
      showLoadingDialog(context);
      UserCredential credential = await _auth.createUserWithEmailAndPassword(email: email, password: password);

      //if user creation is success, create a user model
      if(credential.user == null) return false;
      UserModel user = UserModel(
        uId: credential.user!.uid.toString(),
        name: name,
        email: credential.user!.email.toString(),
        phone: phone,
      );

      //and upload user model to firebase
      await _fireStore.collection('users').doc(credential.user!.uid).set(user.toMap()).then((value){
        showSnackBar(context, "Sign Up Successful!");
      });
      return true;
    }on FirebaseAuthException catch(exception){
      showSnackBar(context, getMessageFromErrorCode(exception.code));
      return false;
    }finally{
      //pops loading dialog
      Navigator.pop(context);
    }
  }

    With the Flutter (and other client-side SDKs) it will always require an extra API call to set the display name of the user.

    If creating the user and setting their display name atomically is a requirement for you app, consider using the Admin SDK in a trusted environment (such as your development machine, a server that you control, or Cloud Functions/Cloud Run) to perform that action atomically, creating an endpoint for your this, and then calling that from your app.
