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 -vas well. Thank you!Minimal sample code

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 17whilst it works normally oniPhone 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.

@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 commentedon Sep 22, 2023
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.
jkgatt commentedon Sep 25, 2023
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:
Reproduced this on three different devices, all on iOS 17.0.1.
The log that seems related to this issue:

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.
