Creates a CupertinoApp.

At least one of home, routes, onGenerateRoute, or builder must be non-null. If only routes is given, it must include an entry for the Navigator.defaultRouteName (/), since that is the route used when the application is launched with an intent that specifies an otherwise unsupported route.

This class creates an instance of WidgetsApp.
