GlassThemeData class

Theme data for liquid glass widgets.

Provides centralized styling for all glass widgets in your app, with automatic light/dark mode support. Brightness is resolved via a priority cascade: GlassThemeData.brightness override → Cupertino explicit pin → Material ThemeMode → system/device setting. This ensures glass widgets always follow the app's intended brightness, not the device OS setting.

Usage

Wrap your app with GlassTheme to provide theme data:

MaterialApp(
  theme: ThemeData.light(),
  darkTheme: ThemeData.dark(),
  builder: (context, child) => GlassTheme(
    data: GlassThemeData(
      light: GlassThemeVariant(
        settings: LiquidGlassSettings(thickness: 30, blur: 3),
        quality: GlassQuality.standard,
      ),
      dark: GlassThemeVariant(
        settings: LiquidGlassSettings(thickness: 40, blur: 5),
        quality: GlassQuality.standard,
      ),
    ),
    child: child!,
  ),
)

Access theme data in widgets:

final theme = GlassThemeData.of(context);
final settings = theme.settings; // Automatically uses light/dark variant
