themeModeNotifier property
The DevTools panel's own theme — independent of the host app's theme. Defaults to dark; toggle with a light/dark ThemeMode via the panel's theme switcher, or set directly:
CorextraDevTools.instance.themeMode = ThemeMode.light;
Implementation
final ValueNotifier<ThemeMode> themeModeNotifier = ValueNotifier<ThemeMode>(
ThemeMode.dark,
);
