so i was building some stuff and ran into issues like where i have a future function called ‘fetchAllJobs’ here is the code

`Future<List<Map<String, dynamic>>> fetchAllJobs() async {
var url = Uri.parse(
‘https://svxuhlltayxjxqrtxgxz.supabase.co/rest/v1/list_of_jobs?select=*’);

try {
  var response = await http.get(url);

  if (response.statusCode == 200) {
    var jsonResponse = jsonDecode(response.body);
    List<dynamic> jobs = jsonResponse as List<dynamic>;

    // Convert List<dynamic> to List<Map<String, dynamic>>
    List<Map<String, dynamic>> jobList =
        jobs.map((job) => job as Map<String, dynamic>).toList();
    return jobList;
  } else {
    throw Exception('Failed to load jobs from Supabase');
  }
} catch (error) {
  debugPrint('Error fetching jobs: $error');
  // You can throw an exception or handle errors as needed
  rethrow;
}

}`

what i am trying to do is where i navigate into the Posted Jobs it throws an error
TypeError (Null check operator used on a null value)

this is the code snipper for the FutureBuilder

FutureBuilder( future: fetchAllJobs(), builder: (context, snapshot) { List<Map<String, dynamic>> job = snapshot.data!;

what is the good way to elimitate this error? i tried putting delay and a initState still errors. thanks in advance.
