  Map<String, dynamic>? userMap;
  late FloatingSearchBarController controller;

  @override
  void initState() {
    super.initState();
    controller = FloatingSearchBarController();
    filteredSearchHistory = filterSearchTerms(filter: null);

      print(userMap);
      Navigator.push(
          context,
          MaterialPageRoute(
              builder: (context) => searchresultPage(
                  recevieduserMap: userMap!['jobType'], key: UniqueKey())));
    });
