  builder: (BuildContext context) { return AlertDialog(content: Text("Saving...")); });
await saveToSomething()
Navigator.of(context, rootNavigator: true).pop();
```

Async Laden initial
===================
* Initial nur den Loading Screen anzeigen
* in InitState das async-Laden aufrufen
* darin await LoadFromSomething()
* dann Navigator.pushReplacement zur Home-Route
