WidgetStateBorderSide class abstract

Defines a BorderSide whose value depends on a set of WidgetStates which represent the interactive state of a component.

To use a WidgetStateBorderSide, you should create a subclass of a WidgetStateBorderSide and override the abstract resolve method.

This class enables existing widget implementations with BorderSide properties to be extended to also effectively support WidgetStateProperty<BorderSide> property values. WidgetStateBorderSide should only be used with widgets that document their support, like ActionChip.side.

This class should only be used for parameters which are documented to take WidgetStateBorderSide, otherwise only the default state will be used.
