[iOS 17] Switching between Chinese and English input on the keyboard freezes

[zhangyanzhu88]

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

flutter版本：3.13.4
iOS版本：ios17 Developer Beta

the steps：
Step 1 Switch the Chinese keyboard and click the keyboard "I".
Step 2 Switch the English keyboard and enter the character "'" and enter the character "m".
Step 3 Enter the character "."
Then it gets stuck, then it crashes, then it goes back.

Expected results

Normal input "i'm."

Actual results

The process is stuck and crashed

Hi @zhangyanzhu88
I checked this issue on iPhone 14 Pro, iOS 17.0 but can't see any crash. I'm using the same XCode Build 15A240d as yours.

Can you try with minimal sample code below? If the crash still occurs, please provide entire stack trace and output of flutter run -v.

And please provide the output of flutter doctor -v as well. Thank you!

Minimal sample code

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: Scaffold(
        body: Center(
          child: TextField(),
        ),
      ),
    );
  }
}

Thanks for the update. I re-formatted your comment for better readability.

Although it's unclear why I couldn't reproduce the issue previously, I can reproduce it now. Reproduced this issue on iPhone 14 Pro, iOS 17 whilst it works normally on iPhone 7, iOS 15.7.2.

Even though I couldn't see any error from the output console, the app was frozen, and couldn't input further.

flutter doctor -v (stable and master)

thank you, look forward to your reply.

cc @LongCatIsLooong from triage.

[stuartmorgan]

Which beta was this reproduced with?

/cc @hellohuanlin

[jason-simmons]

Reproduced this on the release version of iOS 17 at the current Flutter head.

When this happens, the text input plugin seems to be receiving FlutterTextInputView.selectionRectsForRange and FlutterTokenizer.rangeEnclosingPosition(UITextGranularityLine) calls from the _UITextChoiceAccelerationAssistant. These calls occur in an infinite loop that rapidly leaks memory, which soon causes the process to crash.

[stuartmorgan]

@hellohuanlin Assigning to you since you said you were looking into this; if you don't end up having time to work on this please let me know. This is a likely CP candidate (assuming a fix that's viable for CP).

[castleche]

This could repro with iOS 17.0.1. As more users are upgrading to iOS 17, this issue is causing increasingly lost to our app. Hope this can be fixed by Apple or Flutter soon.

Another issue similarly related to this too is when having Auto-Correction on.
Typing in both Japanese or Chinese and English characters seems to hang at some point and crashes the whole app.

Reproducible steps:

1. Add a single character in Japanese/Chinese
2. Change to English and start typing, ensuring you activate auto-correct.
3. App just hangs.

Reproduced this on three different devices, all on iOS 17.0.1.

The log that seems related to this issue:

[hellohuanlin]

quick update that i found a potential fix, which happens to resolve another issue with text input. I am doing more testing in case of regression.

[jkgatt]

@hellohuanlin this is great news, please keep us informed!

[zhangyanzhu88]

@huycozy hi，Is the problem solved?

[hellohuanlin]

@zhangyanzhu88 this is resolved. I think it's also released yesterday iirc.

[zhangyanzhu88]

@hellohuanlin thank you
