displayName showing null after creating user with Firebase Auth

Question

I\'m trying to add a user using the Firebase auth and it returns the displayName as null, even though it asks for it via the UI on sign up. Any ideas why and how to fix? H

You Can Also Get Name From firebaseAuthWithGoogle Method.

  private void firebaseAuthWithGoogle(final GoogleSignInAccount acct) {
  AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener() {
                @Override
                public void onComplete(@NonNull Task task) {

                    if (!task.isSuccessful()) {

                        Toast.makeText(MainActivity.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                    } else {
                        System.out.println(acct.getDisplayName());
                        System.out.println(acct.getPhotoUrl());
                    }

                }
            }); }
