Hello flutter newbie here! I'm using flutter local notifications and adding the default code to my app. It works in Android but doesn't work in iOS. any idea why?

I tried with both the iOS simulator for iPhone 8 and iPhone 11. It works on my android emulator which is a Pixel 3 API 29.

I have also enabled the Notifications in iOS (Settings>this app>Notifications) for this app and gave the permissions.

For Android I have added permission requests in AndroidManifest.xml.

import 'package:flutter/material.dart';
import 'package:flutter_local_notifications/flutter_local_notifications.dart';


class AppNotification extends StatefulWidget {
  static const String id = 'app_notification';

  @override
  _AppNotificationState createState() => _AppNotificationState();
}

class _AppNotificationState extends State<AppNotification> {
  FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin;

  @override
  void initState() {
    super.initState();
    flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();
    var android = AndroidInitializationSettings('app_icon');
    var iOS = IOSInitializationSettings();
    var initSettings = InitializationSettings(android, iOS);

    flutterLocalNotificationsPlugin.initialize(initSettings,
        onSelectNotification: onSelectNotification);
  }

  Future onSelectNotification(String payload) async {
    debugPrint("payload : $payload");
    showDialog(
      context: context,
      builder: (_) {
        return AlertDialog(
          title: Text("PayLoad"),
          content: Text("Payload : $payload"),
        );
      },
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            FlatButton(
              child: Text('Notification'),
              onPressed: _showNotificationWithDefaultSound,
            ),
            FlatButton(
              onPressed: () {
                Navigator.pop(context);
              },
              child: Text('back'),
            )
          ],
        ),
      ),
    );
  }

  // TODO iOS doesn't work

  Future _showNotificationWithDefaultSound() async {
    var androidPlatformChannelSpecifics = new AndroidNotificationDetails(
        'your channel id', 'your channel name', 'your channel description',
        importance: Importance.Max, priority: Priority.High);
    var iOSPlatformChannelSpecifics = new IOSNotificationDetails();
    var platformChannelSpecifics = new NotificationDetails(
        androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
    await flutterLocalNotificationsPlugin.show(
      0,
      'New Post',
      'How to Show Notification in Flutter',
      platformChannelSpecifics,
      payload: 'Default_Sound',
    );
  }

in the notification_service class add requestAlertPermission: true,

Eg:Future initNotification() async { // Android initialization const AndroidInitializationSettings initializationSettingsAndroid = AndroidInitializationSettings('@mipmap/ic_launcher');

// ios initialization
const IOSInitializationSettings initializationSettingsIOS =
    IOSInitializationSettings(
  requestAlertPermission: true,
  requestBadgePermission: false,
  requestSoundPermission: false,
);

const InitializationSettings initializationSettings =
    InitializationSettings(
        android: initializationSettingsAndroid,
        iOS: initializationSettingsIOS);
// the initialization settings are initialized after they are setted
await flutterLocalNotificationsPlugin.initialize(initializationSettings);

}
