Border radius around entire Composer #875
Description
The Composer provides many things that can be customized, including adjusting the border radius and such of the input field itself. However, I cannot see a way to change the border radius of the entire Composer widget. My first instinct was to wrap in a ClipRRect, which visually worked, however my log was filled with exceptions Incorrect use of ParentDataWidget, which I understand is because then the direct parent of the Composer widget is no longer a stack.
Is there a way to add a border radius to the entire Composer widget that I have missed? There appears to be no decoration parameter or anything.
If there currently is no way to do this and it isn't stepping on anyone's toes, I'd be happy to dig into the code and see if I could do it myself.
Thanks!
