        primarySwatch: Colors.indigo,
        brightness: brightness,
      ),
      themedWidgetBuilder: (context, theme) {
        return new MaterialApp(
          title: 'Flutter Demo',
          theme: theme,

        );
      }
    );
  }
}

  void changeBrightness() {
    DynamicTheme.of(context).setBrightness(Theme.of(context).brightness == Brightness.dark? Brightness.light: Brightness.dark);
  }

  void changeColor() {
    DynamicTheme.of(context).setThemeData(new ThemeData(
        primaryColor: Theme.of(context).primaryColor == Colors.indigo? Colors.red: Colors.indigo
    ));
  }
