ValueNotifier<double> progress = ValueNotifier<double>(0);
ValueNotifier<int> currentNumberProgress = ValueNotifier<int>(0);
ValueNotifier<int> totalNumberProgress = ValueNotifier<int>(0);

...

Waiter(
  callback: waiterController,
  onTry: (value) {
    print("onTry");
  },
  firstLoadShowLoading: true,
  progress: progress,
  currentNumberProgress: currentNumberProgress,
  totalNumberProgress: totalNumberProgress,
  onCancelProgress: (value) {
    print("onCancelProgress");
  },
  onDismissProgress: () {
    print("onDismissProgress");
  },
  child: Scaffold(
    ...
  ),
);

...

waiterController.showProgress("progressTag");

totalNumberProgress.value = 1;
currentNumberProgress.value = 1;
progress.value = 50.0;
