$ionicFacebookAuth login not working

ionic-v1
1

Hi,
We’ve been trying to get Native FB Login working (we have the in app browser login working). For some reason when I’m injecting $ionicFacebookAuth in my controller or service, I get “Unknown provider: $ionicFacebookAuthProvider”. This is how my code looks:

package.json
"@ionic/cloud": "^0.13.0",

config.xml

<plugin name="cordova-plugin-facebook4" spec="~1.7.4">
    <variable name="APP_ID" value="12345"/>
    <variable name="APP_NAME" value="xyz"/>
  </plugin>

index.html

  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
    <title></title>

    <script src="lib/bluebird.min.js"></script>

    <script src="lib/ionic/js/ionic.bundle.js"></script>
    <script src="lib/ionic.cloud.min.js"></script>

app.js

angular.module('app', ['ionic', 'ionic.cloud', 'app.controllers', 'app.routes', 'app.directives','app.services'])

.config(function($ionicCloudProvider) {
  $ionicCloudProvider.init({
    "core": {
      "app_id": "12345"
    },
    "auth": {
      "facebook": {
        "scope": ["email", "public_profile"]
      }
    }
  });
})

controllers.js


.controller('loginCtrl', ['$scope', '$stateParams','$ionicAuth', '$ionicUser','$http','$state', 'AuthService',
function ($scope, $stateParams, $ionicAuth, $ionicUser, $http, $state, AuthService) {
  $scope.loginToFB = function() {
    AuthService.loginFB();
  };

services.js

  function($ionicFacebookAuth, $ionicAuth, $ionicUser, $ionicHistory, $http, $state, SecureStorageService) {

    this.loginFB = function () {

  ....

At this point I haven’t even attempted to actually login (using $ionicFacebookAuth.login().then…)
I have the inapp browser login working just fine, but I wanted to get the native logging working. I have the cordova plugin installed and everything. For some reason I’m not able to get past this error.

I realise that this seems like a n00b problem, I apologise in advance for that. But for some reason I just cannot solve this and would appreciate any help.

Thank you!
