CheckboxTheme class Null safety

Applies a checkbox theme to descendant Checkbox widgets.

Descendant widgets obtain the current theme's CheckboxTheme object using CheckboxTheme.of. When a widget uses CheckboxTheme.of, it is automatically rebuilt if the theme later changes.

A checkbox theme can be specified as part of the overall Material theme using ThemeData.checkboxTheme.
