Firebase can not change displayName ,displayName is null on every way

Question

Can't add I more user information with await FirebaseAuth.instance .createUserWithEmailAndPassword(email: _email, password: _password); function?

part of signup.dart file:

 String _email, _password, _name;

  final formkey = new GlobalKey<FormState>();`

  Future<void> registered() async {
    if (formkey.currentState.validate()) {
      formkey.currentState.save();
      try {
        await FirebaseAuth.instance
            .createUserWithEmailAndPassword(email: _email, password: _password);
        FirebaseUser firebaseUser = await FirebaseAuth.instance.currentUser();
        Firestore.instance
            .collection("users")
            .document(firebaseUser.uid)
            .setData({"name": _name});
        await firebaseUser.reload();
        firebaseUser = await FirebaseAuth.instance.currentUser();
        print(
            "${firebaseUser.uid},${firebaseUser.email},${firebaseUser.displayName} , $_password this user has been created-----");
      } catch (e) {
        print("${e.message} message--------------------------------------");
      }
    } else {
      print("somthing went wrong");
    }
  }

I have tried many way to do this but still i have no result

Solution

You are saving data in Firestore, and trying to get the name from Firebase Auth. Those are two services. Instead of trying to use firestore, what you could is,

    FirebaseUser firebaseUser = await FirebaseAuth.instance.currentUser();
    var userUpdateInfo = UserUpdateInfo();
    userUpdateInfo.displayName = _name;
    firebaseUser.updateProfile(userUpdateInfo);
    await firebaseUser.reload();
    firebaseUser = await FirebaseAuth.instance.currentUser();
