Create a bottom sheet

A bottom sheet shows secondary content, anchored to the bottom of the screen.

Version compatibility

This implementation requires that your project minSDK be set to API level 21 or higher.

Dependencies

Implement a bottom sheet

To implement a bottom sheet, use the ModalBottomSheet composable:

Expand and collapse the sheet

To expand and collapse the sheet, use SheetState:

Key points

  • Use the content slot, which uses a ColumnScope to lay out sheet content composables in a column.
  • Use rememberSheetState to create an instance of SheetState that you pass to ModalBottomSheet with the sheetState parameter.

  • SheetState provides access to the show and hide functions and to properties related to the current sheet state. These functions require a CoroutineScope — for example, rememberCoroutineScope — and can be called in response to UI events.

  • Make sure to remove the ModalBottomSheet from composition when you hide the bottom sheet.
