Update 1: Providing a Global Key to the Container in the bottom Sheet forces the keyboard to stay alive, but then a red screen flickers on Ios and i get the following error: I/flutter (15864): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
I/flutter (15864): The following assertion was thrown while finalizing the widget tree:

I/flutter (15864): the widget tree being truncated unexpectedly, because the second time a key is seen, the previous

I/flutter (15864): - [GlobalKey#06a16]
I/flutter (15864): This was determined by noticing that after the widget with the above global key was moved out of its
