DataTableThemeData class Null safety

Defines default property values for descendant DataTable widgets.

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

Typically a DataTableThemeData is specified as part of the overall Theme with ThemeData.dataTableTheme.

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