ThemeModifier class

Applies a theme to descendant widgets.

A theme describes the colors and typographic choices of an application.

Descendant widgets obtain the current theme's ThemeData object using Theme.of. When a widget uses Theme.of, it is automatically rebuilt if the theme later changes, so that the changes can be applied.

The Theme widget implies an IconTheme widget, set to the value of the ThemeData.iconTheme of the data for the Theme.
