Fixes #162215 and partially supports #162181. The Cupertino sheet had two issues layout: It still had MediaQuery padding at the top of the screen as if there was safe area content to avoid and some of the sheet was permanently offscreen. This caused a FloatingActionButton to be clipped, but if you put a scrolling widget in the sheet with text at the very bottom, it was impossible to scroll the text into view. This PR removes the top padding, and changes the bottom padding to equal the amount offscreen.
