Firebase UI Auth 处理来自 SignInScreen (Flutter) 隐式导航的注册操作

Question

I have a sign in screen from SignInScreen widget as shown below.

However, if a user does not have an account he can register himself by clicking Register on the screen which will lead me to this page:

In the documentation, it is called internal navigation: https://github.com/firebase/flutterfire/blob/master/packages/flutterfire_ui/doc/auth/integrating-your-first-screen.md#disabling-internal-navigation

The problem I have right now is once a user register, the user did not receive any notification that his account is successfully registered nor the app will automatically redirect him to the email verification or even back to the sign in page.

How do I handle a registration action from the SignInScreen widget?

Below is the code I have for the SignInScreen widget:

import 'package:firebase_ui_auth/firebase_ui_auth.dart';
import 'package:flutter/material.dart';

class LoginScreen extends StatelessWidget {
  const LoginScreen({super.key});

  @override
  Widget build(BuildContext context) {
    return SignInScreen(
      actions: [
        AuthStateChangeAction<SignedIn>((context, state) {
          if (!state.user!.emailVerified) {
            Navigator.pushNamed(context, '/verify-email');
          } else {
            Navigator.pushReplacementNamed(context, '/profile');
          }
        }),
      ],
    );
  }
}

Answer 1

Solved it by rebuilding my app instead of using hot reload, not sure why it happens though.

Answer 2

I have experienced similar behavior - actually it was due to bug (AuthStateChangeAction was not triggered after registration) and it was resolved just recently (firebase_ui_auth version 1.1.8 has been just published).

It was also possible to work it around by listening to Firebase auth instance directly but now it is no longer necessary.
