Which platforms would this feature impact?

iOS, Android

Is your feature request related to a problem?

I have mobile users with external keyboards who would like to be able to submit messages using a key combination. (Specifically, CMD+Enter on iOS)

It looks like send message key handling was explicitly omitted from mobile in this commit: https://github.com/GetStream/stream-chat-flutter/pull/1222/commits/d3fff37fcdd7adcc1defb63eeeb1d48e422fedbb

Describe the solution that you'd like

I would like to be able to set a sendMessageKeyPredicate and have it be enabled on all platforms. I believe that if omitting that behavior from mobile was desired it should be done when building the predicate.

Describe alternatives that you have considered

@crxm can you try out the branch from #1947 and let me know if it works? I don't have a way to test this at the moment. You can pull the git package from the branch and try out the predicates like normal.

We're testing and merging the probable fix - please feel free to open another issue if you find yourself facing this again.

Thanks!
