}

class _MyAlertState extends State<MyAlert> {
  TextEditingController titleController = TextEditingController();
  @override
  Widget build(BuildContext context) {
 //if you're not using a state management tool to rebuild a certain part
 //the variables below widget build will be reset again 
 //ex: if used setState()
    String dropValue = widget.task['status'];

List<Products> // type
List<dynamic> // dynamic
