CupertinoTheme class Null safety

Applies a visual styling theme to descendant Cupertino widgets.

Affects the color and text styles of Cupertino widgets whose styling are not overridden when constructing the respective widgets instances.

Descendant widgets can retrieve the current CupertinoThemeData by calling CupertinoTheme.of. An InheritedWidget dependency is created when an ancestor CupertinoThemeData is retrieved via CupertinoTheme.of.
