@slawekkrol Thanks for the PR, the code changes themselves looks like it will work. Can you note the iOS version and Flutter version you have tested this on?

Flutter 2.5.3 • channel stable
Tools • Dart 2.14.4
iOS 15.2

But IMO this really doesn't matter because this change is only native ObjC code in one place, so this code must works on every version iOS and flutter

Thanks for providing those details.
