Flutter: Value is empty

A.file

void drawMarkers(){
    Marker marker = Marker();
    marker.getListFromFirestore(users);
    marker.getList(); <---- here2
  }

void initState() {
    // TODO: implement initState
    drawMarkers();
    super.initState();
  }

B.file

class Marker{
  List<Model> list;

  void getListFromFirestore(List<dynamic> users) async {
    list = await NetworkRepository.fetchListsFromAllUsers(users); <---- here1
  }
       
  List<Model> getList(){
    return list;
  }
}

In my code, value of list is not empty (here1). But at here2 the value is empty. what's wrong in my code?

You need to await the call to getListFromFirestore, since it is async:

Future<void> drawMarkers() async{
    Marker marker = Marker();
    await marker.getListFromFirestore(users);
    marker.getList(); <---- here2
}
