`Error: Unresolved reference to Angular service`

I'm encountering an issue in my Ionic/Cordova application where I am trying to implement a loading message using $ionicLoading, but I keep getting the error:

ReferenceError: $ionicLoading is not defined

Does anyone know how I can successfully pass $ionicLoading into my service?

Any help would be greatly appreciated.

/**
 * Service for handling calls
 */
.factory('DialService', function() {
    return {
        makeCall: function(number) {
            $ionicLoading.show({
                template: 'TEST',
                duration: 1000
            });

            window.cordova.plugins.DirectCallPlugin.call(number, callSuccessCallback, callFailCallback);
        }
    };

    var callSuccessCallback = function() {
        console.log("Success call");
    };

    var callFailCallback = function() {
        console.log("Call failed");
        $ionicLoading.show({
            template: 'Error during call dial',
            duration: 1000
        });
    };

});

Answer №1

Change the following code snippet:

.factory('DialService', function() {

To this:

.factory('DialService', function($ionicLoading) {

Ensure that:

  • The script is properly loaded in your index.html
  • ionic is included as a dependency of your angular module
