Constructors

SDropdownMenuMorph({required List<SMenuItem> items, Key? key, Widget? child, SDropdownMenuStyle style = const SDropdownMenuStyle(), Curve curve = Curves.easeInOutCirc, Duration duration = const Duration(milliseconds: 250), void onChange(T value, int index)?, SMenuController? controller, Widget? header, Widget? footer, double height = 350, double width = 250, Widget? icon, SDropdownMenuPosition? position = SDropdownMenuPosition.bottomCenter, Widget builder(BuildContext context, List<SMenuItem> items)?, SMenuItemStyle buttonStyle = const SMenuItemStyle()})
const

Properties

builder → Widget Function(BuildContext context, List<SMenuItem> items)?
The builder that makes the menu. Completely overwrites the menu for complete customization. This means many menu parameters will not work.
finalinherited
buttonStyle → SMenuItemStyle
The style of the dropdown menu button
finalinherited
child → Widget?
The child widget for the dropdown menu button
finalinherited
controller → SMenuController?
The optional controller for this menu

onChange → void Function(T value, int index)?
onChange is called when the selected option is changed.; It will pass back the value and the index of the option.
finalinherited
performanceMode → bool
