Answer 1

Sample code:

 @override
  void initState() {
    super.initState();

    asyncOperation().then((val) {
      setState(() {});
      print("success");
    }).catchError((error, stackTrace) {
      print("outer: $error");
    });

//or

    asyncOperation().whenComplete(() {
      setState(() {});
      print("success");
    }).catchError((error, stackTrace) {
      print("outer: $error");
    });
  }

  Future asyncOperation() async {
    await ... ;
  }
