CupertinoTheme class
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.
The CupertinoTheme widget implies an IconTheme widget, whose IconTheme.data has the same color as CupertinoThemeData.primaryColor

- CupertinoThemeData, specifies the theme's visual styling.
- CupertinoApp, which will automatically add a CupertinoTheme based on the value of CupertinoApp.theme.
- Theme, a Material theme which will automatically add a CupertinoTheme with a CupertinoThemeData derived from the Material ThemeData.
