FTheme class - forui.theme library (original) (raw)

Applies a theme to descendant widgets.

A theme configures the colors and typographic choices of Forui widgets. The actual configuration is stored in a FThemeData. Descendant widgets obtain the current theme's FThemeData via either FThemeBuildContext.theme, or FTheme.of. When a widget uses either, it is automatically rebuilt if the theme later changes.

class Parent extends StatelessWidget {
  @override
  Widget build(BuildContext context) => FTheme(
     data: FThemes.zinc.light,
     child: Child(),
   );
 }

 class Child extends StatelessWidget {
   @override
   Widget build(BuildContext context) {
     final FThemeData theme = context.theme;
     final FThemeData sameTheme = FTheme.of(context);

     return const Placeholder();
   }
 }

See FThemeData which describes of the actual configuration of a theme.
