How to unschedule previously scheduled local notifications after some time? - flutter

Question

I am using flutter_local_notifications library to schedule local notifications every 1 hour. It is working as expected but now, I need a way to start/ stop the notification schedule (say, at push of a button).
I could not find anything regarding canceling scheduled notification requests in the documentation.

Answer 1

Cancelling/deleting a notification
// cancel the notification with id value of zero
await flutterLocalNotificationsPlugin.cancel(0);
// 0 is your notification id
Cancelling/deleting all notifications
await flutterLocalNotificationsPlugin.cancelAll();
And yes, this can cancel current and future notification. Just make sure correct notification id.

Answer 2

In the docs it is given in Cancelling/deleting a notification
await flutterLocalNotificationsPlugin.cancel(0);

Answer 3

I would do something like this:
final FlutterLocalNotificationsPlugin _flutterLocalNotificationsPlugin =
FlutterLocalNotificationsPlugin();
// Below will give you any unpresented/scheduled notifications
final List<PendingNotificationRequest> pendingNotificationRequests =
await _flutterLocalNotificationsPlugin.pendingNotificationRequests();
for (var _pendingRequest in pendingNotificationRequests) {
_flutterLocalNotificationsPlugin.cancel(_pendingRequest.id);
}
Here _pendingRequest.id will give you the required notification id to cancel the specific notification request.
This is tested in Android. Will update the status on iOS soon.

Answer 4

await flutterLocalNotificationsPlugin.cancelAll(); //cancel future note
await flutterLocalNotificationsPlugin.pendingNotificationRequests(); //restart note
And your notification will show again.

Answer 5

If you want to cancel all notifications, then you have to do that using the following:
await flutterLocalNotificationsPlugin.cancelAll();
Also, if you want to cancel a specific notification, you can do this by using a specific ID of your notification:
await flutterLocalNotificationsPlugin.cancel(0); // 0 is your notification id
Where this notification ID came from ??
While you are declaring your notification to show on your screen you have to add some data like given below:
await _flutterLocalNotificationsPlugin.show(
0, // this is the notification id
message.notification.title,
message.notification.body,
notificationDetails,
payload: jsonEncode(message.data),
);
Here I am using Flutter Local Notification Plugin to show notifications!!!
Hope this will solve your problem.
