我想借助一个按钮来启用/禁用通知服务，当启用此按钮时，用户会收到通知，而当它被禁用时，他将不会收到任何通知。

import 'dart:io';

import 'package:firebase_messaging/firebase_messaging.dart';

class FirebaseNotifications {
  FirebaseMessaging _firebaseMessaging;

  void setUpFirebase() {
    _firebaseMessaging = FirebaseMessaging();
    firebaseCloudMessaging_Listeners();

  }

  void firebaseCloudMessaging_Listeners() {
    if (Platform.isIOS) iOS_Permission();

    _firebaseMessaging.getToken().then((token) {
      print(token);
    });

    _firebaseMessaging.configure(
      onMessage: (Map<String, dynamic> message) async {
        print('on message $message');
      },
      onResume: (Map<String, dynamic> message) async {
        print('on resume $message');
      },
      onLaunch: (Map<String, dynamic> message) async {
        print('on launch $message');
      },
    );
  }

  void iOS_Permission() {
    _firebaseMessaging.requestNotificationPermissions(
        IosNotificationSettings(sound: true, badge: true, alert: true));
    _firebaseMessaging.onIosSettingsRegistered
        .listen((IosNotificationSettings settings) {
      print("Settings registered: $settings");
    });
  } …
