Set counter of notification using awesome_notification flutter - flutter

Question

I am using awesome_notifications: ^0.0.6+12 as a local notification that shows notification/information on the status bar of the device. So far the function to show a notification runs very well, but I got a problem with the counter of notification.
As we know.. when one notification pops up there will be a flag counter in our icon apps 1 and when the second notification pops up.. it will turn into 2
But, the problem is... when I click the notification from the status bar and then the app is opening, the counter is still 1 while.. it should be removed after I click it... Is there a way to solve this? here is the part of the code
notifRequirement() {
AwesomeNotifications().actionStream.listen((notification) {
if (notification.channelKey == 'basic_channel' && Platform.isIOS) {
AwesomeNotifications().getGlobalBadgeCounter().then(
(value) =>
AwesomeNotifications().setGlobalBadgeCounter(value - 1),
);
}
Navigator.pushAndRemoveUntil(
context,
MaterialPageRoute(
builder: (_) => MainScreen(),
),
(route) => route.isFirst,
);
});
}
I call notifRequirement inside initState and in main.dart:
AwesomeNotifications().initialize(
'resource://drawable/darisdmmodified',
[
NotificationChannel(
channelKey: 'scheduled',
channelName: 'Scheduled Notifications',
defaultColor: Colors.red,
locked: false,
importance: NotificationImportance.High,
channelShowBadge: true,
channelDescription: "description 1"),
],
);
