onInit method

@override void onInit()

Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.

Implementation

@override
void onInit() {
  super.onInit();
  _brightness = SchedulerBinding.instance.window.platformBrightness.obs;
  final String? source = _preferences.getString(_themeModeKey);
  if (source != null) {
    themeMode.value = parse(source);
  }
}
