PlatformWidgetBase<M extends Widget, D extends Widget, W extends Widget> class abstract

An abstract class used as a building block for creating PlatformWidgets.

This class broadly covers the platforms by combining Android and iOS together as a "mobile" category, macOS, Windows, and Linux together as a "desktop" category. This is useful is cases where a widget is expected to be the same for the various mobile and desktop categories, and would therefore be tedious to return the same widget more than once for the specified category. This is unlike DesktopWidgetBase, which more specifically targets the various platforms in the "desktop" category.

This class utilizes generics to define the types of widgets it expects to build:

  • M = Mobile
  • D = Desktop
  • W = Web
