Thank you for the PR. I like the idea in generall and this basically replicates what already happens on iOS, however I don't like that this requires unfocusing. It would worth figuring out if we can hide the keyboard without unfocus (same behavior as iOS).

@knopp Hello! Thanks for review, sure we achieve the same behaviour using native methods:

SystemChannels.textInput.invokeMethod('TextInput.hide') and SystemChannels.textInput.invokeMethod('TextInput.show');

but in this case - we need to check if the keyboard was visible before we hide it to understand do we need to reopen it. But for that need to add package [https://pub.dev/packages/flutter_keyboard_visibility] .

I am not sure that you will approve adding some additional libraries to your package

Instead of adding a dependency that is only used on one platform, I'd probably go with implementing a method channel call handler in SuperNativeExtensionsPlugin that'd query whether keyboard is visible. Looking at flutter_keyboard_visibility they seem to do it simply based on ratio of windowVisibleDisplayFrame / root view.

We only need a very small part of the plugin functionality and only one one platform, that's why I don't want to introduce a dependency for this.
