A material design bottom sheet.
There are two kinds of bottom sheets in material design:
-
Persistent. A persistent bottom sheet shows information that supplements the primary content of the app. A persistent bottom sheet remains visible even when the user interacts with other parts of the app. Persistent bottom sheets can be created and displayed with the
Scaffold.showBottomSheetfunction. -
Modal. A modal bottom sheet is an alternative to a menu or a dialog and prevents the user from interacting with the rest of the app. Modal bottom sheets can be created and displayed with the showModalBottomSheet function.
The BottomSheet widget itself is rarely used directly. Instead, prefer to
create a persistent bottom sheet with Scaffold.showBottomSheet and a modal
bottom sheet with showModalBottomSheet.
