android – FlutterError : The important thing [LabeledGlobalKey] was utilized by a number of widgets

I am getting an error whereas attempting to navigate to the menu_screen widget. I am fairly certain that the GlobalKey menuFormKey isn’t used inside one other widget however I do not perceive why I am getting this downside.

There’s the code of menu_screen :

import 'dart:async';

import 'package deal:flutter/materials.dart';

class MenuScreen extends StatefulWidget {
  bool darkish;
  Menu menu;
  MenuScreen({Key? key, required this.darkish, required this.menu})
      : tremendous(key: RIKeys.riKey3);

  @override
  State<MenuScreen> createState() => _MenuScreenState();
  static String id = "MenuScreen";
}

class _MenuScreenState extends State<MenuScreen> {
  last StreamController<Menu> _currentMenuStreamCtrl =
      StreamController<Menu>.broadcast();
  Stream<Menu> get onCurrentMenuChanged => _currentMenuStreamCtrl.stream;
  void updateCurrentMenuUI() => _currentMenuStreamCtrl.add(widget.menu);
  GlobalKey<FormState> menuformKey =
      GlobalKey<FormState>(debugLabel: "menu type Key");
  @override
  Widget construct(BuildContext context) {
    Measurement deviceSize = MediaQuery.of(context).dimension;
    Orientation deviceOrientation = MediaQuery.of(context).orientation;
    bool isPortrait = deviceOrientation == Orientation.portrait;
    double screenWidth = isPortrait ? deviceSize.width : deviceSize.peak;
    double screenHeight = isPortrait ? deviceSize.peak : deviceSize.width;
    return MaterialApp(
      residence: SafeArea(
        youngster: Scaffold(
          appBar: AppBar(
            main: IconButton(
              icon: Icon(Icons.arrow_back),
              onPressed: () {
                Navigator.pop(context);
              },
            ),
            title: Textual content(
              "Modify Menu",
              model: TextStyle(

              ),
            ),
            actions: [
              IconButton(
                onPressed: () {

                    menuformKey.currentState!.save();

            ],
