getInitialNotificationAction abstract method
Gets the notification action that launched the app. If the app
wasn't launched by a notification, so it returns null. This method does
not depend on setListeners being called first.
removeFromActionEvents when set to true, prevents the same action from
being delivered in the method onActionMethod, in case it hasn't already
happened
Implementation
Future<ReceivedAction?> getInitialNotificationAction(
{bool removeFromActionEvents = false});
