I am using flutter_local_notification V 5.00+3 and call flutterLocalNotificationsPlugin.pendingNotificationRequests()
always returns 0 (zero) , even if I execute
FlutterLocalNotificationsPlugin().show
twice and do not click the notification, leaving the notification, the code is shown below and is taken from the example with simple modification of adding idOfMsg as id of message.

Please help so that I can get list of notifications that are still not clicked by user nor cancelled.
pendingNotificationRequests is for scheduled notification that has not yet appeared in notification panel.
getActiveNotifications is for notifications that are available in notification panel.
