I am having text input filed (see attachment) which shows suffix icon. on clicking suffix icon i want to get text in textfield.

Please can anyone help me out.

My code is below but its not getting the value to text field

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:geolocator/geolocator.dart';
import 'package:flutter_map/flutter_map.dart';

 
class NoteScreen extends StatefulWidget {
  final Note note;
  NoteScreen(this.note);
 
  @override
  State<StatefulWidget> createState() => new _NoteScreenState();
}
 
class _NoteScreenState extends State<NoteScreen> {
  DatabaseHelper db = new DatabaseHelper();
 
  TextEditingController _titleController;
  TextEditingController _descriptionController;
 
  @override
  void initState() {
    super.initState();
    getUserLocation();
    _titleController = new TextEditingController(text: widget.note.title);
    _descriptionController = new TextEditingController(text: widget.note.description);
  }

  LatLng _center ;
  Position currentLocation;

  MapController _mapctl = MapController();


  Future<Position> locateUser() async {
    try{
      return await Geolocator()
        .getCurrentPosition(desiredAccuracy: LocationAccuracy.high);
    }on PlatformException catch(e){
      currentLocation = null;
    }
    return currentLocation;
  }

  getUserLocation() async {
    currentLocation = await locateUser();
    setState(() {
      _center = LatLng(currentLocation.latitude, currentLocation.longitude);
    });
    print('center $_center');
  }
 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Add Plant'),
        actions: <Widget>[
            new IconButton(
              icon: const Icon(Icons.view_list),
              tooltip: 'Next choice',
              onPressed: () {
              navigateToPlantList();
              },
              ),
          ]
        ),
        body: Container(
          margin: EdgeInsets.all(15.0),
          alignment: Alignment.center,
          child: Column(
            children: <Widget>[
              TextField(
                  controller: _descriptionController,
                  decoration: InputDecoration(
                    labelText: 'Get current location',
                    suffixIcon: IconButton(
                      icon: Icon(Icons.location_on),
                      onPressed: (){
                        Text(_center.toString());
                        print(_center);
                      }
                    )),
                  
                  ),
              TextField(

                    onPressed: () {
                      if (widget.note.id != null) {

                            Navigator.pop(context, 'update');
                            });
                            }else {
                              db.saveNote(Note(_titleController.text, _descriptionController.text)).then((_) {
                                Navigator.pop(context, 'save');
                                });
                              }
                            },
                          ),
                        ],

                    ),
                  );
                }
                void navigateToPlantList() {
                   Navigator.push(context,

try this inside getUserLocation

setState(() {
    _center = LatLng(currentLocation.latitude, currentLocation.longitude);


    _descriptionController.text = _center.toString()
});
