RadioThemeData class Null safety

Defines default property values for descendant Radio widgets.

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

Typically a RadioThemeData is specified as part of the overall Theme with ThemeData.radioTheme.

All RadioThemeData properties are null by default. When null, the Radio 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 Radio properties for details.
