How to pass Data between two Screens in Dart

Issue

I need to send data to another screen using dart I try to make constructor on the other screen(editdata.dart) to get the data from the main screen (readdata.dart) it is stateful widget the problem in: createState() => EditFire() EditFire class need to pass parameters but I don't have the data yet.

editdata.dart:

class EditData extends StatefulWidget {
  @override

  //Here the Error Occurs//

  State<StatefulWidget> createState() => EditFire();
}

class EditFire extends State<EditData> {
  EditFire(String ID, String date, String time, String dest, String src){
    currentID = ID;
    olddate = date;
    oldtime = time;
    _destinationcontroller.text = dest;
    _sourcecontroller.text = src;
  }
  late String currentID;
  final _destinationcontroller = TextEditingController();
  final _sourcecontroller = TextEditingController();
  late String olddate;
  late String oldtime;
}

in readdata.dart:

EditFire("2","17/6/2022","2:25","NewYork","Japan");

Solution

First page

onPressed: () { 
      Navigator.of(context).push(MaterialPageRoute(builder: (_){
        return EditData("2","17/6/2022","2:25","NewYork","Japan");
      }));
    },

Second page in which you want to receive data

class EditData extends StatefulWidget {

 String currentID;
   String _destinationcontroller;
   String _sourcecontroller;
   String olddate;
   String oldtime;


   EditData(this.currentID, this._destinationcontroller, this._sourcecontroller,
      this.olddate, this.oldtime, {Key? key}) : super(key: key);

  @override
  State<EditData> createState() => _EditDataState();
}

class _EditDataState extends State<EditData> {

  @override
  Widget build(BuildContext context) {
    return Container(
      child: Center(child:
        Text('${widget.currentID}'),),
    );
  }
}
