Flutter local notifications daily scheduled notification - flutter

Question

I've been trying to get Flutter local notifications to work since a week but can't get it to work.
Basically the issue is whenever i create a daily notification, it works only for the first time and then it doesn't show notifications every next day.
Suppose if i set daily scheduled notification at 12:20 PM, it will show notification at 12:20 PM for first time, then the next day it won't show. And when i see the list of pending notifications i can see the notification still present.
here's all my notification code
class NotificationService {
// Singleton pattern
static final NotificationService _notificationService =
NotificationService._internal();
factory NotificationService() {
return _notificationService;
}
NotificationService._internal();
static const channelId = "1";
final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
FlutterLocalNotificationsPlugin();
static const AndroidNotificationDetails _androidNotificationDetails =
AndroidNotificationDetails(
channelId,
"thecodexhub",
channelDescription:
"This channel is responsible for all the local notifications",
playSound: true,
priority: Priority.high,
importance: Importance.high,
);
static const IOSNotificationDetails _iOSNotificationDetails =
IOSNotificationDetails();
final NotificationDetails notificationDetails = const NotificationDetails(
android: _androidNotificationDetails,
iOS: _iOSNotificationDetails,
);
Future<void> init() async {
const AndroidInitializationSettings androidInitializationSettings =
AndroidInitializationSettings('#mipmap/ic_launcher');
const IOSInitializationSettings iOSInitializationSettings =
IOSInitializationSettings(
defaultPresentAlert: false,
defaultPresentBadge: false,
defaultPresentSound: false,
);
const InitializationSettings initializationSettings =
InitializationSettings(
android: androidInitializationSettings,
iOS: iOSInitializationSettings,
);
// *** Initialize timezone here ***
tz.initializeTimeZones();
await flutterLocalNotificationsPlugin.initialize(
initializationSettings,
onSelectNotification: onSelectNotification,
);
}
Future<void> requestIOSPermissions() async {
await flutterLocalNotificationsPlugin
.resolvePlatformSpecificImplementation<
IOSFlutterLocalNotificationsPlugin>()
?.requestPermissions(
alert: true,
badge: true,
sound: true,
);
}
Future<void> showNotification(
int id, String title, String body, String payload) async {
await flutterLocalNotificationsPlugin.show(
id,
title,
body,
notificationDetails,
payload: payload,
);
}
Future<void> scheduleNotification(int id, String title, String body,
DateTime eventDate, TimeOfDay eventTime, String payload,
[DateTimeComponents? dateTimeComponents]) async {
final scheduledTime = eventDate.add(Duration(
hours: eventTime.hour,
minutes: eventTime.minute,
));
await flutterLocalNotificationsPlugin.zonedSchedule(
id,
title,
body,
tz.TZDateTime.from(scheduledTime, tz.local),
notificationDetails,
uiLocalNotificationDateInterpretation:
UILocalNotificationDateInterpretation.absoluteTime,
androidAllowWhileIdle: true,
payload: payload,
matchDateTimeComponents: dateTimeComponents,
);
}
Future<void> cancelNotification(int id) async {
await flutterLocalNotificationsPlugin.cancel(id);
}
Future<void> cancelAllNotifications() async {
await flutterLocalNotificationsPlugin.cancelAll();
}
Future getNotifications() async {
final List<PendingNotificationRequest> pendingNotificationRequests =
await FlutterLocalNotificationsPlugin().pendingNotificationRequests();
return pendingNotificationRequests;
}
}
Future<void> onSelectNotification(String? payload) async {
// await navigatorKey.currentState
// ?.push(MaterialPageRoute(builder: (_) => DetailsPage(payload: payload)));
}
and here's how i'm calling it.
await notificationService.scheduleNotification(
1,
_textEditingController.text,
"Reminder for your scheduled event at ${eventTime!.format(context)}",
eventDate!,
eventTime!,
jsonEncode({
"title": _textEditingController.text,
"eventDate": DateFormat("EEEE, d MMM y").format(eventDate!),
"eventTime": eventTime!.format(context),
}),
getDateTimeComponents(),
);
}
here is getDateTimeComponents if it matters
DateTimeComponents? getDateTimeComponents() {
if (segmentedControlGroupValue == 1) {
return DateTimeComponents.time;
} else if (segmentedControlGroupValue == 2) {
return DateTimeComponents.dayOfWeekAndTime;
}
}
it's been week since i'm trying to fix this issue.
Thank you for reading.

Answer 1

Here it says
Use zonedSchedule instead by passing a date in the future with the
same time and pass DateTimeComponents.matchTime as the value of the
matchDateTimeComponents parameter.
You seem to use DateTimeComponents.time correctly but I guess your date is not in the future. Can you try adding like a thousand years to your date and see? Maybe because after the first firing, the date is now in the past and it will not fire on the next day because of it.
