Firebase UI Auth is a set of Flutter widgets and utilities designed to help you build and integrate your user interface with Firebase Authentication.

Please contribute to the discussion with feedback.

1. Available with flutterfire_desktop
2. No deep-linking into app, so email verification link opens a web page

flutter pub add firebase_ui_auth

Here's a quick example that shows how to build a SignInScreen and ProfileScreen in your app

import 'package:flutter/material.dart';
import 'package:firebase_auth/firebase_auth.dart' hide EmailAuthProvider;
import 'package:firebase_ui_auth/firebase_ui_auth.dart';
class MyApp extends StatelessWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context) {
    final providers = [EmailAuthProvider()];
    void onSignedIn() {
      Navigator.pushReplacementNamed(context, '/profile');
    }
    return MaterialApp(
      initialRoute: FirebaseAuth.instance.currentUser == null ? '/sign-in' : '/profile',
      routes: {
        '/sign-in': (context) {
          return SignInScreen(
            providers: providers,
            actions: [
              AuthStateChangeAction<UserCreated>((context, state) {
                // Put any new user logic here
                onSignedIn();
              }),
              AuthStateChangeAction<SignedIn>((context, state) {
                onSignedIn();
              }),
            ],
          );
        },
        '/profile': (context) {
          return ProfileScreen(
            providers: providers,
            actions: [
              SignedOutAction((context) {
                Navigator.pushReplacementNamed(context, '/sign-in');
              }),
            ],
          );
        },
      },
    );
  }
}

If you're using ProfileScreen, make sure to add the following to your pubspec.yaml:

fonts:
  - family: SocialIcons
    fonts:
      - asset: packages/firebase_ui_auth/fonts/SocialIcons.ttf
