🐛 [firebase_ui_auth] SignInScreen() does not trigger AuthStateChangeAction event (Flutter)

Bug report

Describe the bug When using the prebuilt SignInScreen and passing the actions parameter AuthStateChangeAction <UserCreated> or AuthStateChangeAction<SignedIn>, despite a user being successfully registered or signed in via Firebase Auth these callback events never fire.

Steps to reproduce

Steps to reproduce the behavior:

Use prebuilt SignInScreen from firebase_ui_auth
Pass in callback actions
Sign in or register on the app SignInScreen and notice no event callback fired.

Expected behavior

The event should fire (in this case just add a simple print statement)

Sample project

import 'package:firebase_auth/firebase_auth.dart'
    hide PhoneAuthProvider;
import 'package:firebase_ui_auth/firebase_ui_auth.dart';
import 'package:firebase_ui_oauth_google/firebase_ui_oauth_google.dart';
import 'package:flutter/material.dart';

import 'home.dart';

class AuthGate extends StatefulWidget {
  const AuthGate({Key? key}) : super(key: key);

  @override
  _AuthGateState createState() => _AuthGateState();
}

class _AuthGateState extends State<AuthGate> {
  @override
  void initState() {
    super.initState();
    FirebaseAuth.instance.authStateChanges().listen((user) {
      print('FirebaseAuth.instance.authStateChanges()');
      print(user);
    });
  }

@override

            },
