CatalystProvider class

Convenience widget that sets up the full Catalyst UI scope in one step.

Place this inside your navigator (e.g. as the home of a WidgetsApp) to wire up theming and all Catalyst overlay dependencies at once.

Light theme only:

CatalystProvider(
  theme: ThemeData.light(fontFamily: 'Inter'),
  child: MyHomePage(),
)

Automatic dark / light switching:

CatalystProvider(
  theme: ThemeData.light(fontFamily: 'Inter'),
  darkTheme: ThemeData.dark(fontFamily: 'Inter'),
  child: MyHomePage(),
)

Force a specific mode:

CatalystProvider(
  theme: ThemeData.light(fontFamily: 'Inter'),
  darkTheme: ThemeData.dark(fontFamily: 'Inter'),
  themeMode: ThemeMode.dark,
  child: MyHomePage(),
)
