Async data on InitState method - dart/flutter

dart

I was struggling in finding a way to load async data on Initial State method

I found the answer here: https://stackoverflow.com/questions/51901002/is-there-a-way-to-load-async-data-on-initstate-method

This is my concrete example

  setInitialValueQuestionReview() async {
    late DocumentReference<Map<String, dynamic>> testAnwDB = FirebaseFirestore
        .instance
        .collection('AppUsers')
        .doc(currentUser!.uid)
        .collection('test_settings')
        .doc('personalised_Settings');

    var querySnapshot = await testAnwDB.get();
    var personalisedSettingsData = querySnapshot.data();
    _questionReview.text = personalisedSettingsData!['reviewSesion'].toString();
    _isSelectedShowBoth = personalisedSettingsData['showBoth'];
    _isSelectedShowCorrectas = personalisedSettingsData['showCorr'];
    _isSelectedShowIncorrectas = personalisedSettingsData['showInCorr'];
  }

  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance?.addPostFrameCallback((_) {
      setInitialValueQuestionReview();
    });
  }
