🐛 [FlutterFireUI] Browser do not offer to store password on web

[Leffe108]

Bug report

Describe the bug I created a FlutterFire demo app where I use SignInScreen widget for sign in UI. When I test it out in Flutter Web (in Chrome and Firefox), the browser do not offer to save the username + password in the in-browser password manager.

In flutter issue #61301 there are some answers suggesting to configure autofillHints on the fields and wrapping with AutofillGroup. Looking at the FlutterFire UI source code it seems that this is not set for the EmailForm widget used by SignInScreen under the hood.

If Flutter Web do support autofill working with password managers (which the above issue seems to indicate), I expect the FlutterFire UI to have support for it.

Steps to reproduce

Steps to reproduce the behaviour:

1. Open demo project in VS code and run it with chrome as target.
2. Click on Register button in the UI
3. Enter an email and a password (and the same password again in Confirm password)
4. Click on Register button.

Browser does not offer to store the password.

Expected behavior

I expect that when I create user and/or login that Chrome/Firefox offers to store the password in the in-browser password manager.

Sample project

Use flutterfire CLI to generate firebase_options.dart. Enable email provider in Firebase console.

main.dart

```dart import 'package:flutter/material.dart'; import 'package:firebase_auth/firebase_auth.dart'; import 'package:firebase_core/firebase_core.dart'; import 'package:flutterfire_ui/auth.dart'; import 'firebase_options.dart'; void main() async { WidgetsFlutterBinding.ensureInitialized(); await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform); runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({Key? key}) : super(key: key); // This widget is the root of your application. @override Widget build(BuildContext context) { return MaterialApp( title: 'Firebase Demo', theme: ThemeData( primarySwatch: Colors.blue, ), home: const MyHomePage(), ); } } class MyHomePage extends StatelessWidget { const MyHomePage({Key? key}) : super(key: key); @override Widget build(BuildContext context) { final auth = FirebaseAuth.instance; return StreamBuilder( stream: auth.authStateChanges(), builder: (context, snaphot) => auth.currentUser == null ? const Login() : const Home(), ); } } class Login extends StatelessWidget { const Login({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return SignInScreen( providerConfigs: const [ EmailProviderConfiguration(), ], headerMaxExtent: 64, headerBuilder: (BuildContext context, BoxConstraints constraints, double shrinkOffset) { return AppBar(title: const Text("Firebase Demo")); }, ); } } class Home extends StatelessWidget { const Home({Key? key}) : super(key: key); @override Widget build(BuildContext context) { final user = FirebaseAuth.instance.currentUser; return Scaffold( appBar: AppBar( title: Text('Hi ${user?.displayName ?? user?.email ?? 'someone'}!'), actions: [ TextButton( child: const Icon( Icons.logout, color: Colors.white, semanticLabel: 'Log out', ), onPressed: () { FirebaseAuth.instance.signOut(); }, ), ], ), body: Column( children: const [ Text('Logged in'), ], ), ); } } ```

Looks like there is a recent PR to fix this: https://github.com/FirebaseExtended/flutterfire/pull/7668 :-)

[darshankawar]

The PR fix would hopefully resolve your issue. Also, it may not have been a bug, probably the plugin doesn't yet support autofill until the PR was raised. So I suggest you to keep an eye or subscribe to that PR for further updates.

[tguidoux]

Same thing for me, browser is not saving anything. I tried with AutofillGroup etc :slightly_smiling_face:

[lesnitsky]

after firebase/flutterfire#7668 is merged chrome now suggests saving password, but username is missing: flutter/flutter/issues/97653

Hi everyone,

I'm using flutterfire_ui: ^0.4.3+6, credentials (email, password) are correctly saved by browsers but they are not be filled in when the browser suggests to use saved credentials.

Are there any updates on this topic?

[lesnitsky]

as of Flutter 3.13.1 • channel stable and firebase_ui_auth: 1.7.0 this works as expected (browser prompts to save the password and shows autofill hints).

Hi lesnitsky, is it also working for iOS? Thank you.
