[Android] Autofill from saved credentials doesn't work

[TatsuUkraine]

Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

1. Create a form with username and password field
2. Try to use password manager such as Google Password Manager
3. Ensure that password usage requires biometric auth (not sure if it changes anything)
4. Click in Key icon on keyboard and select password

Device for testing

Google Pixel 7 pro, Android 14 (34)

Expected results

Form prepopulates with the selected username/password combination

Actual results

Input loses focus and nothing happens.

Form can be prepopulated only if login/password combination is selected from Keyboard quick actions and no biometric check is requested

Code sample

Code sample (very simple autofillgroup with 2 inputs)

           AutofillGroup(
              child: Column(
                children: [
                  TextField(
                    autofillHints: [AutofillHints.username],
                  ),
                  TextField(
                    autofillHints: [AutofillHints.password],
                  ),
                ],
              ),
            ),

Hi @TatsuUkraine. When you setup details, have you also set those up in the system "autofill service" settings and provide relevant information to the autofill service for it to work ?

[TatsuUkraine]

@dam-ease sorry, not sure that I understood the question( for this example I didn't do any native configuration for Android, basically this issue appears only when app looses focus either because of biometric auth or because you go into the password manager. If biometric auth is not requested, and you using password suggestions from the keyboard quick action - all works fine

[TatsuUkraine]

@dam-ease I already replied😅

[TatsuUkraine]

@dam-ease I added video to the description to better explain what is going on. On a video when screen goes black - it asks for biometric verification. On a video there are 3 attempts:

1. Using Key icon to go to the password manager.
2. Using quick action with biometric verification
3. Using quick action without biometric verification

Autofill works only when app doesn't go to background (3rd try)

[dam-ease]

I guess the time you replied and the time the label updated were the same.
We can reproduce the issue when clicking on Key icon > select saved account (without needing biometric verification). We tested with a Realme 6, Android 11.
Can you confirm again if you also can see the issue when removing biometric verification or not?

[TatsuUkraine]

It seems biometric verification doesn't affect behavior a lot. If I disable biometric check for password usages only one difference is that there is no scenario 2 (from my prev comment). So it seems autofill just stops working when the app goes to background and the text field loses focus, either because of password manager bottom sheet or because of biometric check

screen-20231103-160500.2.mp4

Also, one note, I'm not entirely sure, since I didn't check this explicitly, but I think all was working in prev stable release

[davidpryor]

I am seeing this same behavior while using 1password.
When required to first unlock the manager AND/OR attempting to fill the password from the "open 1password" option, the fields will not fill.

Once the manager is unlocked, 1password can fill as expected from the small "account choosing" modal, but still cannot fill from the "open 1password" option.

It seems this happens any time my app is pushed to the background by the password manager.

IF I force the focusNode for the username field to never loose focus by requesting focus when the focusNode is not in focus, it will autofill. It seems like the password manager does not/cannot regain focus on the textfield before it attempts to push the username/password text.

Attaching a video from a sample app.
The black screen is the 1password biometric auth popup, then the login selector.

I started to notice this issue once my device got Android 14 update. on Android 13 it was working fine.

[djsjr]

Developed a workaround using a combination of FocusNodes, listeners, and watching LifeCycle changes. It seems to be working for me.

1. Initialize FocusNodes and pass them to your text inputs.
2. Create a AppLifecycleState state variable.
3. Implement the didChangeAppLifecycleState method, and update state each time it changes.
4. Create a listener for each node, in which you requestFocus() if state == AppLifecycleState.inactive.

Example:

class _SignInFormState extends State<SignInForm> with WidgetsBindingObserver {
  late FocusNode passwordNode;
  late FocusNode emailNode;
  AppLifecycleState state = AppLifecycleState.resumed;

  @override
  void didChangeAppLifecycleState(AppLifecycleState state) {
    super.didChangeAppLifecycleState(state);
    this.state = state;
  }

  @override
  void initState() {
    WidgetsBinding.instance.addObserver(this);
    passwordNode = FocusNode();
    passwordNode.addListener(() async {
      if (state == AppLifecycleState.inactive)
        passwordNode.requestFocus();

    });
    emailNode = FocusNode();
    emailNode.addListener(() async {
      if (state == AppLifecycleState.inactive) 
        emailNode.requestFocus();
    });
    super.initState();
  }

  @override
  void dispose() {
    WidgetsBinding.instance.removeObserver(this);
    passwordNode.dispose();
    emailNode.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return 
        ...
        TextField(
            focusNode: emailNode, 
        ...
        TextField(
            focusNode: passwordNode,
        ...
    }
}

(Thanks to @davidpryor for mentioning forcing focus).

[vbuberen]

Can also confirm that the workaround works. Thanks a lot for this!

However, I also have a small nitpick to it - super.initState() should be called first in the override as mentioned in the documentation:

flutter/packages/flutter/lib/src/widgets/framework.dart

Lines 998 to 999 in 5187b45

	/// Implementations of this method should start with a call to the inherited
	/// method, as in `super.initState()`.

So the initState() should look like this and it works fine 😉 :

@override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addObserver(this);
    passwordNode = FocusNode();
    passwordNode.addListener(() async {
      if (state == AppLifecycleState.inactive)
        passwordNode.requestFocus();

    });
    emailNode = FocusNode();
    emailNode.addListener(() async {
      if (state == AppLifecycleState.inactive) 
        emailNode.requestFocus();
    });
  }

Can also confirm that the workaround works. Thanks a lot for this!

This works for TextField but not for TextFormField in a form. That's fine though; I don't need the whole form.

[TatsuUkraine]

Developed a workaround using a combination of FocusNodes, listeners, and watching LifeCycle changes. […]

another possible workaround (depends on what kind of form you have on the screen)

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

class InactiveFocusScopeObserver extends StatefulWidget {
  final Widget child;

  const InactiveFocusScopeObserver({
    super.key,
    required this.child,
  });

  @override
  State<InactiveFocusScopeObserver> createState() => _InactiveFocusScopeObserverState();
}

class _InactiveFocusScopeObserverState extends State<InactiveFocusScopeObserver> {
  final FocusScopeNode _focusScope = FocusScopeNode();

  AppLifecycleListener? _listener;
  FocusNode? _lastFocusedNode;

  @override
  void initState() {
    _registerListener();

    super.initState();
  }

  @override
  Widget build(BuildContext context) => FocusScope(
    node: _focusScope,
    child: widget.child,
  );

  @override
  void dispose() {
    _listener?.dispose();
    _focusScope.dispose();

    super.dispose();
  }

  void _registerListener() {
    /// optional if you want this workaround for any platform and not just for android
    if (defaultTargetPlatform != TargetPlatform.android) {
      return;
    }

    _listener = AppLifecycleListener(
      onInactive: () {
        _lastFocusedNode = _focusScope.focusedChild;
      },
      onResume: () {
        _lastFocusedNode = null;
      },
    );

    _focusScope.addListener(_onFocusChanged);
  }

  void _onFocusChanged() {
    if (_lastFocusedNode?.hasFocus == false) {
      _lastFocusedNode?.requestFocus();
      _lastFocusedNode = null;
    }
  }
}

so it can be used with any number of fields that may potentially suffer from this bug

InactiveFocusScopeObserver(
  child: FormWithTheFeildsThatMayLooseFocus(),
)

The workaround mentioned in this thread works fine for android. But I haven't been able to get iOS to work. The save password prompt doesn't show up. Does any one here have a working solution for iOS? Please share.

[zigapovhe]

Our clients reported exactly the same issue, but we can replicate it even without having biometric auth enabled for autofill. Using inline autofill (via keyboard), try to not directly autofill credentials, but via IME, open autofill app, and try autofilling from there.

It indeed looks like the issue is lost focus. We replicated that on Google Password Manager and on Bitwarden everytime.

[LongCatIsLooong]

I can't reproduce the issue with biometric authentication on:

video.mp4

[LongCatIsLooong]

Additional note:

flutter/packages/flutter/lib/src/widgets/focus_manager.dart

Lines 1524 to 1533 in 6826fc0

	if (kIsWeb || defaultTargetPlatform != TargetPlatform.android) {
	// It appears that some Android keyboard implementations can cause
	// app lifecycle state changes: adding this listener would cause the
	// text field to unfocus as the user is trying to type.
	//
	// Until this is resolved, we won't be adding the listener to Android apps.
	// https://github.com/flutter/flutter/pull/142930#issuecomment-1981750069
	_appLifecycleListener = _AppLifecycleListener(_appLifecycleChange);
	WidgetsBinding.instance.addObserver(_appLifecycleListener!);
	}

It doesn't seem that moving the app to the background affects the in-app focus on Android (at least not in the framework).

@LongCatIsLooong In which version of flutter did you test it? I am testing it on version 3.19.6, and I can reproduce the issue, in my case it happens with Samsung Account on a physical device, using biometric authentication, it does not autocomplete the textfields (email and password).

[adonisRodxander]

UPDATE: On version 3.22.0 works fine

[LongCatIsLooong]

Looks like the first bad commit is 04e284a. The issue went away when the commit was reverted.

[gnprice]

Looks like the first bad commit is 04e284a. The issue went away when the commit was reverted.

To unpack this a bit:
Commit 04e284a was an engine roll, pulling in flutter/engine@c97a0deccbc1.

That engine commit was reverted in flutter/engine@500ae6c.

That revert rolled into flutter/flutter in commit d35c08e, which was part of Flutter 3.22.0 but not 3.19.6 (the previous release).

[udaychandra]

We're facing the same issue with password autofill.

Using Flutter 3.22.1

[TatsuUkraine]

All works fine for me on Android after update to 3.22.1. Fields aren't loosing focus during biometric verification in password manager. Login and password prefilled correctly in the form

[TatsuUkraine]

@LongCatIsLooong I don't know why bot reopened the issue, sorry 😅

[AristideVB]

@LongCatIsLooong I don't know why bot reopened the issue, sorry 😅

Might be a sign ! 😄 On Android Username is not saved to Google Password Manager for me, only suggested password

While on iOS existing password autofill does not fill the fields anymore (but I will investigate and open an issue)

[zigapovhe]

Jup, works for me on android, but I still have the same old issues on iOS build
