Trigger event for Ionic 4 local Notification

Ionic Framework
1

Hi Guys currently trying to implement a location based local Notification - that when a user enters a locations radius - they are notified - probably easy I know… But Im new enough and Im not exactly sure how to declare the trigger
I’ve been referencing

https://github.com/katzer/cordova-plugin-local-notifications#location-based,
Heres my code:

app.t

export class AppComponent:

notificationSent = false;

trackLat;

trackLng;

lat;

lng;

x = 53.5017237;

y = - 6.460589116;

radius = 500;

trigger;

initializeApp

this.backgroundMode.on(‘activate’).subscribe(() => {
console.log(‘activated’);

  const location = this.geolocation.watchPosition();

  location.subscribe((location) => {

this.trackLat = location.coords.latitude;

this.trackLng = location.coords.longitude;

if (location === this.trigger(‘location’)) {

this.locationNotification();
}

});

locationNotification() {
this.localNotification.schedule({
id: 2,
title: ‘Welcome to the show grounds!’,
text: ‘Click me to declare your entries!!’,
sound: ‘’,
trigger: {
type: ‘location’,
center: [this.x, this.y],
radius: this.radius,
notifyOnEntry: true,
notifyOnExit: false,
single: true
},
vibrate: true,
foreground: true
});
}

I know I’m not calling the trigger of the notification correctly - If anyone can help me out it would be amazing!

The error I forgot to add - is just coming up as INVALID and then I can see the notification in the xcode terminal
