Local Notifications

Initialize the Plugin
The initializeTimeZone must be initialized before use. Add this code somewhere in your app (e.g., in main.dart or a separate setup function):

add custom action initializeTimeZoneto Initial Actions at main.dart
timezone: ^0.10.0
// Required imports for timezone package import 'package:timezone/timezone.dart' as tz; import 'package:timezone/data/latest_all.dart' as tz; // Action to initialize time zones Future initializeTimeZone() async { // Load the timezone database tz.initializeTimeZones(); }

Add custom actions initializeNotifications at home page loading

flutter_local_notifications: ^18.0.1


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

final flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();

Future<void> initializeNotifications() async {
  final androidSettings = AndroidInitializationSettings('@mipmap/ic_launcher');
  final iosSettings = DarwinInitializationSettings();
  await flutterLocalNotificationsPlugin.initialize(
      InitializationSettings(
        android: androidSettings,
        iOS: iosSettings,
      ), onDidReceiveNotificationResponse: (payload) {
    if (payload != null) {
      print('Notification Response: $payload');
    }
  });

  // Create the notification channel for Android
  const AndroidNotificationChannel channel = AndroidNotificationChannel(
    'channel_id',
    'channel_name',
    description: 'channel_description',
    importance: Importance.max,
    playSound: true,
  );
  await flutterLocalNotificationsPlugin
      .resolvePlatformSpecificImplementation<
          AndroidFlutterLocalNotificationsPlugin>()
      ?.createNotificationChannel(channel);

  // Request permissions for iOS
  await flutterLocalNotificationsPlugin
      .resolvePlatformSpecificImplementation<
          IOSFlutterLocalNotificationsPlugin>()
      ?.requestPermissions(
        alert: true,
        badge: true,
        sound: true,
      );
}

Use this custom actions scheduleNotification to set notification


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

// Define this globally (outside the function) and initialize it elsewhere
final flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();

Future scheduleNotification(
  String title,
  String body,
  DateTime scheduleTime, // Already a DateTime, no parsing needed
) async {
  // Get the local time zone
  final localTz = tz.local;

  // Convert scheduleTime to TZDateTime for timezone-aware scheduling
  final tzScheduleTime = tz.TZDateTime.from(scheduleTime, localTz);

  // Schedule the notification
  await flutterLocalNotificationsPlugin.zonedSchedule(
    0, // notificationId
    title,
    body,
    tzScheduleTime,
    const NotificationDetails(
      android: AndroidNotificationDetails(
        'channel_id',
        'channel_name',
        importance: Importance.max,
        priority: Priority.high,
      ),
      iOS: DarwinNotificationDetails(),
    ),
    androidScheduleMode: AndroidScheduleMode.exact, // Added required parameter
    uiLocalNotificationDateInterpretation:
        UILocalNotificationDateInterpretation.absoluteTime,
  );
}

I tested it's work on iOS - real device.
