CheckboxThemeData class Null safety

Defines default property values for descendant Checkbox widgets.

Descendant widgets obtain the current CheckboxThemeData object using CheckboxTheme.of(context). Instances of CheckboxThemeData can be customized with CheckboxThemeData.copyWith.

Typically a CheckboxThemeData is specified as part of the overall Theme with ThemeData.checkboxTheme.

All CheckboxThemeData properties are null by default. When null, the Checkbox will use the values from ThemeData if they exist, otherwise it will provide its own defaults based on the overall Theme's colorScheme. See the individual Checkbox properties for details.
