SwitchTheme class Null safety

Applies a switch theme to descendant Switch widgets.

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

A switch theme can be specified as part of the overall Material theme using ThemeData.switchTheme.
