onReady method
override
    Called 1 frame after onInit(). It is the perfect place to enter navigation events, like snackbar, dialogs, or a new route, or async request.
Implementation
@override
void onReady() {
  Log.debug('onReady()', '$runtimeType');
  // Don't check for updates in [WebUtils.isPopup].
  if (!WebUtils.isPopup) {
    fetchUpdates();
    if (Config.appcast.isNotEmpty || PlatformUtils.isWeb) {
      _timer = Timer.periodic(_refreshPeriod, (_) {
        fetchUpdates();
      });
    }
  }
  super.onReady();
}
