getNotificationAppLaunchDetails always returns null on iOS but not on Android.

I am testing getNotificationAppLaunchDetails method so that I can navigate to a specific screen when the notification is tapped. It works as intended on Android but not on iOS. on iOS it just returns null. Notification was created using scheduleNotification function.
import 'package:flutter_local_notifications/flutter_local_notifications.dart';

import 'package:timezone/timezone.dart' as tz;

final flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();

  static const String _channelId = 'high_importance_channel';
  static const String _channelName = 'High Importance Notifications';
  static const String _channelDescription = 'Notification for SpendWise';

  static Future init() async {
    tz.initializeTimeZones();

        AndroidInitializationSettings(
      '@mipmap/ic_launcher',

    final DarwinInitializationSettings initializationSettingsDarwin =
        DarwinInitializationSettings(
            onDidReceiveLocalNotification: (id, title, body, payload) {});

    final InitializationSettings initializationSettings =
        InitializationSettings(
      android: initializationSettingsAndroid,
      iOS: initializationSettingsDarwin,
    );

    flutterLocalNotificationsPlugin.initialize(
      initializationSettings,
    );

    if (defaultTargetPlatform == TargetPlatform.android) {
      const AndroidNotificationChannel channel = AndroidNotificationChannel(
        _channelId,
        _channelName,
        importance: Importance.max,
      );
      await flutterLocalNotificationsPlugin
          .resolvePlatformSpecificImplementation<
