Flutter - setState not updating inner Stateful Widget

Question

Basically I am trying to make an app whose content will be updated with an async function that takes information from a website, but when I do try to set the new state, it doesn

Answer 1

don't use a future within a future; use different function that will return each future individually like this

 List requestsData;
 List requestsDocumentData;
 var docId;



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

    getRequestDocs();
  }

  Future getData() {
    var _auth = FirebaseAuth.instance;
    return _auth.currentUser();
  }

  getRequestDocs() {
    getData().then((FirebaseUser user) {
      this.setState(() {
        docId = user.uid;
      });
    });

    FireDb()
        .getDocuments("vendorsrequests")
        .then((List documentSnapshots) {
      this.setState(() {
        requestsDocumentData = documentSnapshots;
      });
    });

    for (DocumentSnapshot request in requestsDocumentData) {
      this.setState(() {
        requestsData.add(Requests(
            request.documentID,
            request.data['requests'],
            Icons.data_usage,
            request.data['requests'][0],
            "location",
            "payMessage",
            "budget",
            "tokensRequired",
            "date"));
      });
    }
  }

you can create individual functions for

  FireDb().getDocuments("vendorsrequests")
            .then((List documentSnapshots) {
          this.setState(() {
            requestsDocumentData = documentSnapshots;
          });
        });

and

  for (DocumentSnapshot request in requestsDocumentData) {
          this.setState(() {
            requestsData.add(Requests(
                request.documentID,
                request.data['requests'],
                Icons.data_usage,
                request.data['requests'][0],
                "location",
                "payMessage",
                "budget",
                "tokensRequired",
                "date"));
          });
        }
