LocalNotifications: How to unregister event listener?

Ionic Framework ionic-v3
1

I have an event listener in the constructor of one of my pages:

  LocalNotifications.on("trigger", (notification, state) => this.locallyNotified);
}

locallyNotified(notification, state) {
  // ...
}

In the source for katzer/cordova-plugin-local-notifications (https://github.com/katzer/cordova-plugin-local-notifications/blob/327f01f9e407b13c236b96e3353c86552185ee89/www/local-notification.js) I found this:

/***********
 EVENTS
***********/
        /**
         * Register callback for given event.
         *
         * @param {String} event
         *      The event's name
         * @param {Function} callback
         *      The function to be exec as callback
         * @param {Object?} scope
         *      The callback function's scope
         */
        exports.on = function (event, callback, scope) {
            this.core.on(event, callback, scope);
        };
      
        /**
         * Unregister callback for given event.
         *
         * @param {String} event
         *      The event's name
         * @param {Function} callback
         *      The function to be exec as callback
         */
        exports.un = function (event, callback) {
            this.core.un(event, callback);    
        };

But exports.un doesn’t exist in the Ionic Native wrapper. What gives? How do I get rid of the event listener when I no longer need it?

did you end up figuring this out? un is in the ionic wrapper now, so the typescript checker doesn’t complain, but the function never executes.

Sorry, I don’t remember.
