  14. AdaptiveSelectionMode? selectionMode,
})

Show modal action sheet, whose appearance is adaptive according to platform

style specifies the style of the sheet. The isDismissible parameter only works for material style and it specifies whether the bottom sheet will be dismissed when user taps on the scrim.
