RoundedBottomSheet class

A material design modal bottom sheet.

• 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 showRoundedModalBottomSheet function.

The RoundedBottomSheet widget itself is rarely used directly. Instead, prefer to create a modal bottom sheet with showRoundedModalBottomSheet.
