Theme 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.
See also:
- ThemeData, which describes the actual configuration of a theme.
- AnimatedTheme, which animates the ThemeData when it changes rather than changing the theme all at once.
- MaterialApp, which includes an AnimatedTheme widget configured via the MaterialApp.theme argument.
