Flutter – Non-nullable instance field 'searchResultsFuture' must be initialized. How do i resolve this without using late

<kbd>
class _SearchState extends State<Search> {
  TextEditingController searchController = TextEditingController();
  Future<QuerySnapshot> searchResultsFuture; //The problem is here


  handleSearch(String query) {
    Future<QuerySnapshot> user =
        usersRef.where("displayName", isGreaterThanOrEqualTo: query).get();
    //.getDocuments()
    setState(() {
      searchResultsFuture = user;
    });
  }

</kbd>

Have used late Future searchResultsFuture;
and the highlighted error gone but the code didn’t work
