SExtensionsScreenUtil class

A widget that initializes the FlutterSExtensions package with a given design-time screenSize and wraps the provided app widget.

This widget should be placed at the root of the widget tree (above MaterialApp/CupertinoApp) so that the design-size is set once and the extension context is updated before any descendant widgets are built.
