# Sheet constructor

Sheet({

1. SheetMode mode = SheetMode.COLLAPSED_SHEET,
2. CollapsedVisibleHeight collapsedVisibleHeight = CollapsedVisibleHeight.SMALL,
3. BadgedButton? listButton,

})

## Implementation

    Sheet({
      this.mode = SheetMode.COLLAPSED_SHEET,
      this.collapsedVisibleHeight = CollapsedVisibleHeight.SMALL,
      BadgedButton? listButton,
    }) : listButton = listButton ?? BadgedButton();
