// Define what you want additionally in dark and light theme
class MyThemeExtensions {
  late Color brandColor;

  MyThemeExtensions({
    Color? brandColor,
  }) : brandColor = brandColor ?? Colors.green.shade400;
}

// Define your own theme query data for easy access
class MyTheme extends CustomThemeQueryData<MyThemeExtensions> {
  MyTheme({
    required ThemeData dark,
    required ThemeData light,
    ThemeMode themeMode = ThemeMode.dark,
  }) : super(
          dark: dark,
          light: light,
          themeMode: themeMode,

          lightCustom: MyThemeExtensions(brandColor: Colors.white70),
        );

  static MyTheme of(BuildContext context) {
