The error occurs only on iOS 18.2.

Thanks a lot.

I'm using several flutter UIs on webview.
I'm experiencing a lot of issues.
I don't know if this is an iOS 18.2 issue, flutter SDK issue, or inappwebview package issue.
Thank you.

[ttb-inc]

If you can review that the error is not related to the inappwebview package, I will repost it to the flutter forum.
Thank you.

webview_flutter: 4.10.0

I've checked the webview_flutter package and found the same error.
I will post the same on flutter forum.
Thank you.
