From our material design catalog page, I tried to find examples of "BottomSheet" and came up empty: https://github.com/flutter/flutter/search?utf8=%E2%9C%93&q=path%3Aexamples+%22new+BottomSheet%22&type=Code

1. Do we have example of BottomSheet, and is GitHub's search not finding it?

2. Can we add examples of BottomSheets? :)

Thanks!
