Ionic cordovaPushV5 initialize error: Can't find variable: PushNotification

I'm getting mad about it. Trying to implement the last cordova push notification repository (cordovaPushV5) but when it look into the console it said ReferenceError: Can't find variable: PushNotification. But the wierd thing here is that if I call the PushNotification from console, it exist.

Here goes some code

$(document).ready(function() {


    // notification

    var options = {
      android: {
        senderID: "THE_NUMBER"
      },
      ios: {
        alert: "true",
        badge: "true",
        sound: "true"
      },
      windows: {}
    };

    // initialize
    $cordovaPushV5.initialize(options).then(function() {
      // start listening for new notifications
      $cordovaPushV5.onNotification();
      // start listening for errors
      $cordovaPushV5.onError();

      // register to get registrationId
      $cordovaPushV5.register().then(function(registrationId) {
        console.log('registrationId: ',registrationId);
      })
    });

    // triggered every time notification received
    $rootScope.$on('$cordovaPushV5:notificationReceived', function(event, data){
      console.log(data);
    });

    // triggered every time error occurs
    $rootScope.$on('$cordovaPushV5:errorOcurred', function(event, e){
      console.log('event: ', event);
      console.log('error: ', e);
    });


  });

EDIT

I have set a timeout of 10 seconds before the plugin init and it works, but shouldn't work this way, any thoughts?

This answer could be useful for similar other issues.

I had the exact same issue. Fixed it.

My issue was: I was using older Angular version ie. 1.4.5 so it was generating a wrong older version of dependencies. It essentially happended while I was upgrading GCM to FCM and I upgraded the plugin to 'phonegap-plugin-push:^2.2.0'.

The solution is: In order to fix that, once I ran 'ionic cordova build android' command then I explicitely changed other dependencies manaually (as below) and re-build it and everything was working fine.

ie. (my-app)-build.gradle

    buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.1'
        classpath 'com.google.gms:google-services:4.1.0'
    }
}

// apply plugin: 'com.google.gms.google-services'
// class must be used instead of id(string) to be able to apply plugin from non-root gradle file
ext.postBuildExtras = {
    apply plugin: com.google.gms.googleservices.GoogleServicesPlugin
}

and "project.properties" file
