Daily recurring notifications in flutter

Question

I am trying to use the plugin, flutter_local_notifications to send recurring notifications to the user, every day but the resource available for the plugin consists of only code and is incomprehensible, I have done the setup for the plugin as follows:

• added the dependency of flutter_local_notifications
• added the permission code for iOS in the AppDelegate.swift

I did this much by referring to numerous resources like medium and a few other sites, so can someone please write a method which sends the user (android & iOS) a recurring notification everyday? Thank you!

Solution 1

After writing that comment I did a bit of research and this is working for me so far:

Future<void> showAlertNotification() async {
    var time = Time(8, 0, 0);
    var androidChannel = AndroidNotificationDetails(
        'channelID', 'channelName', 'channelDescription',
        importance: Importance.defaultImportance,
        priority: Priority.defaultPriority,
        playSound: true);

    var iosChannel = IOSNotificationDetails();
    var platformChannel =
        NotificationDetails(android: androidChannel, iOS: iosChannel);
   await flutterLocalNotificationsPlugin.showDailyAtTime(2, 'notification title',
            'message here', time, platformChannel,
            payload: 'new payload'));
  }

Solution 2

You should not use showDailyAtTime as of now it has quite a number of problems like syncing up with local time zones. So instead you should use the zoned schedule but you should first initialize it with your local time zone it can be done with another package called flutter_native_timezone. This is the workflow I used:

import 'package:timezone/timezone.dart' as tz;
import 'package:timezone/data/latest.dart' as tz;
Future<void> showNotif() async {
tz.initializeTimeZones();
String dtz = await FlutterNativeTimezone.getLocalTimezone();
if (dtz == "Asia/Calcutta") {
  dtz = "Asia/Kolkata";
}
final localTimeZone = tz.getLocation(dtz);
tz.setLocalLocation(localTimeZone);
await _flutterLocalNotificationsPlugin.zonedSchedule(..., matchDateTimeComponents: DateTimeComponents.time);
}

// The ... above is the usual parameters that I didn't write.

I am sorry I did not, I found a resource for scheduled notifications but not recurring ones.
