DataTableTheme class Null safety

Applies a data table theme to descendant DataTable widgets.

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

A data table theme can be specified as part of the overall Material theme using ThemeData.dataTableTheme.
