Current Behavior

After the event of the flutter Button UI is pressed, the event of the webview is not pressed.

The error occurs only on iOS 18.2.
Works fine on iOS 18.1.1 and earlier.

If I'm doing something wrong or need additional options, please help.
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.
