TextFormField is not focused when tapping it again after entering Japanese characters without pressing done but closing keyboard

[shm40]

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. Add a Japanese Keyboard to your iPad
2. Run the below code sample
3. Enter あいう (these are Japanese characters) on TextFormField A
4. Tap the right bottom button on the keyboard
5. Tap TextFormField A again
6. Enter あいう (but nothing reflects on TextFormField A)

I am testing this on iPad Air third generation on iPad OS 16.6.1.

Expected results

Without even tapping the done button on the keyboard, any Japanese characters can be reflected after opening the keyboard again.

Actual results

Any Japanese characters cannot be reflected on TextFormFiled after hiding the keyboard from the right bottom button.

Code sample

Code sample

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

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

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  const HomePage({super.key});

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: ListView(
        padding: const EdgeInsets.all(16),
        children: [
          TextFormField(
            decoration: const InputDecoration(labelText: 'TextFormField A'),
          ),
          TextFormField(
            decoration: const InputDecoration(labelText: 'TextFormField B'),
          ),
        ],
      ),
    );
  }
}

Hi @shm40. Thanks for filing this.
I'm trying to reproduce this on an iPad Air (5th generation), iOS 16.4 but can't seem to reproduce this. Can you try on other simulator versions to see if this reproduces there as well or if this could be device-specific?

@dam-ease
Thanks for trying this issue if it can reproduce.
When I tried this case on the Simulator, there was no problem. But when I use the physical device, it happens.
Could you please try not on the Simulator but the physical device if you have any?

[dam-ease]

Thanks for your response. I don't have a physical device with this specification to test this on my end but I tested on a physical iPhone 13 device and couldn't reproduce this.
Per the video attached in the original comment, I'll be labelling this for more insights from the team.
Thank you!

Thanks for testing on the physical device but iPhone.
I also tested on my iPhone X but it seems that the issue happens only on the physical iPad device.

I really hope that anyone who has a physical iPad device could test this case.
Thanks.

[LongCatIsLooong]

/cc @LongCatIsLooong to repro on a physical iPad.

Thanks for testing on the physical device but iPhone. I also tested on my iPhone X but it seems that the issue happens only on the physical iPad device.

I really hope that anyone who has a physical iPad device could test this case. Thanks.

I also encountered this issue, my device is an iPad (9th generation) #141546

[wanjm]

I have encoutered this too in #142294 and #142437;
and operate sequence is exactly the same; when reproduce you should use the bottom-right key instead of the done/enter key;
it can be reproduced with iPad of 15.X and 16.X using flutter 3.13 and above ; flutter 3.10 had no such problem;
iPad 17 had no such problem;

[wanjm]

@huycozy @dam-ease @danagbemava-nc I hope you can find a physical device to help reproduce it; and hope we can make some progress;

Please!

[shm40]

I tested this issue on Flutter 3.19.2 but could not reproduce so it might be fixed through Flutter upgrade.

@wanjm I hope you can test the same issue where it could be reproduced and report the result.

[hohoins]

The same problem can be reproduced in flutter 3.19.2. Please check and respond.
#144768

In my environment, it can be reproduced starting from flutter 3.13.0. Note please.
————————————
3.3.10 X
3.7.12 X
3.10.7 X
————————————
3.13.0 O It is reproduced.
3.13.9 O It is reproduced.
3.19.2 O It is reproduced.

@shm40 @dam-ease
This problem is currently being reproduced in flutte 3.19.2.
It can be reproduced on the actual iPad device.
The keyboard can be reproduced by setting it to Japanese (romaji).

If this problem occurs once, the app will malfunction from then on until you run the app again.
As an example, even after moving to another screen, the keyboard is displayed when you touch the screen.

The problem is serious. Once this happens, it becomes difficult to use the App anymore.
It definitely needs correction.
I hope this will be fixed in the next version of Flutter.

Please respond to the issue.

[sanghyuk-nam]

I was able to reproduce it by pressing the hide button at the bottom right of the iPad software keyboard.

[hohoins]

I was able to reproduce it by pressing the hide button at the bottom right of the iPad software keyboard.

you're right. Same in my case.
This was reproduced when I pressed the keyboard down button located at the bottom right of the keyboard.

@hohoins @sanghyuk-nam @shm40 please thumbs the first post, and try to make it be noticeable;

flutter 3.19.3

code: https://github.com/hohoins/flutter_text_field_issue/blob/main/lib/main.dart
repo: https://github.com/hohoins/flutter_text_field_issue

The flutter TextField bug on iOS devices is a serious and critical problem.
The flutter app I developed has many users in Japan.
This Japanese keyboard bug is fatal to Japanese users.
Once the problem occurs, the problem persists even on screens without a TextField until the app is restarted.

To inform flutter developers of the seriousness of the problem, I have attached a demo app and a reproduction video.
Please find the cause and fix it.

Just using the TextField widget can cause fatal problems in users' apps.
I hope this will be fixed in the next flutter version.

If you know the email address of someone who can fix this problem, please contact me.
thank you

@hohoins
Thanks for your reports.
I tested this issue with your sample code on iPad Airt 3rd gen with iPad OS 17.3.1 but could not reproduce it.

It seems that your iPad OS Version is older than me.
Could you please test the issue again after upgrading the iPad OS version?

b8a3584d-74ec-4753-9932-f4f87867f09e.mp4

Thank you for your interest in this bug.
I will try to reproduce it again by updating iPad OS.
I will contact you.
thank you
👍👍👍👍👍👍👍

[hohoins]

@shm40

I upgraded to iOS 17.4.1 on my iPad.
After the upgrade, it seems that it cannot be reproduced by simply opening and closing the keyboard.
👍👍👍👍👍

But if I change the way I reproduce it, it's still possible.
If you need to register a new issue, please contact me.
A reproduction video is attached.

How to reproduce:

1. Enter a few characters of text in TextField
2. Select a letter by long pressing it in the TextField
3. Press the back button on the keyboard to delete a letter
4. Close the keyboard with the down button at the bottom right of the keyboard.
5. TextField does not respond when touched

If reproduction is not possible, repeat the above process.
In my case, it was possible to reproduce it within 10 times.
If I put my mind to it, I can 100% reproduce it.

Reproducible keyboard:

• japanese romaji
• english (us)
• korean
  It appears to be reproduced regardless of keyboard language.

[LongCatIsLooong]

I tried this on a device with an older version of iPadOS (13.3), and iOS17.2 simulator. The bug is not reproducible on either of them. It looks like this isn't reproducible on iOS 17+ devices so I'll close this one as not reproducible anymore.

@hohoins I'm not able to reproduce the other bug either, could you create a new issue for this?

[hohoins]

@LongCatIsLooong @shm40
The issue has been closed.
But it didn't solve the TextField issue.
This issue is still reproducible in the latest version.
It even has nothing to do with keyboard language settings.
I plan to register this phenomenon as a separate issue.
thank you

[wanjm]

@hohoins where is your new issue;
