ScrollbarTheme class Null safety

Applies a scrollbar theme to descendant Scrollbar widgets.

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

A scrollbar theme can be specified as part of the overall Material theme using ThemeData.scrollbarTheme.
