We are working on a** flutter app **that allow users to schedule a medicine reminder so they can add the name and the dosage,etc…, and the times they want to get notified so we tried to use awesome notification package and implement it but the notifications didn’t come so what we can do ? (we used firebase firestore to store data)
here is a snippet of code for the notification setup :
import 'package:awesome_notifications/awesome_notifications.dart';
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:fireproject/Medicine_log/models/medicine.dart';
import 'package:timezone/data/latest.dart' as tz;
import 'package:timezone/timezone.dart' as tz;
import 'package:fireproject/Medicine_log/models/medicine.dart';
// Notification service class for managing and scheduling notifications.
class NotificationService {
// Firestore instance for fetching medication data.
final FirebaseFirestore _firestore = FirebaseFirestore.instance;
// Variable to keep track of notification IDs.
int _notificationId = 0;
// Constructor to initialize time zones for scheduling.
NotificationService() {
tz.initializeTimeZones();
}
// Method to handle events when a notification is created.
@pragma('vm:entry-point')
static Future<void> onNotificationCreatedMethod(
ReceivedNotification receivedNotification) async {}
// Method to handle events when a notification is displayed.
@pragma('vm:entry-point')
static Future<void> onNotificationsDisplayedMethod(
ReceivedNotification receivedNotification) async {}
// Method to handle events when a notification dismiss action is received.
@pragma('vm:entry-point')
static Future<void> onDismissActionReceivedMethod(
ReceivedAction receivedAction) async {}
// Method to handle events when a user taps on a notification or action button.
@pragma('vm:entry-point')
static Future<void> onActionReceiveMethod(
ReceivedAction receivedAction) async {}
// Method to schedule notifications based on the medicine data.
Future<void> scheduleNotificationsBasedOnMedicine() async {
// Set the timezone location for scheduling.
final location = tz.getLocation('Asia/Amman');
// Fetch all medicines from Firestore.
QuerySnapshot querySnapshot = await _firestore.collection('medicine').get();
for (var doc in querySnapshot.docs) {
Medicine medicine = Medicine.fromFirestore(doc);
// Loop through each reminder time for the medicine.
for (var reminderTimestamp in medicine.reminderTime) {
DateTime utcScheduledTime = reminderTimestamp.toDate();
tz.TZDateTime scheduledTime =
tz.TZDateTime.from(utcScheduledTime, location);
// Schedule the notification.
await AwesomeNotifications().createNotification(
content: NotificationContent(
id: _notificationId++, // Incrementing ID for each notification.
channelKey: 'basic_channel',
title: 'Medicijne Herinnering', // Title for the notification.
body:
'${medicine.dosage} ${medicine.name} innemen.', // Body text for the notification.
),
schedule: NotificationCalendar.fromDate(
date: scheduledTime), // Scheduling details.
);
}
}
}
}
and this is for add reminder page :
