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.

Constructors

of(BuildContext context) → DataTableThemeData: Returns the configuration data from the closest DataTableTheme ancestor. If there is no ancestor, it returns ThemeData.dataTableTheme. Applications can assume that the returned value will not be null.
