FluentTheme class

Applies a Fluent Design theme to descendant widgets.

A FluentTheme widget provides color, typography, and other design tokens that are used by Fluent UI widgets throughout your application.

To obtain the current theme, use FluentTheme.of to access the nearest FluentThemeData in the widget tree:

final theme = FluentTheme.of(context);
final accentColor = theme.accentColor;

{@tool snippet} This example shows how to apply a custom theme to a subtree:

FluentTheme(
  data: FluentThemeData(
    accentColor: Colors.green,
    brightness: Brightness.dark,
  ),
  child: MyWidget(),
)

{@end-tool}
