How to get the authenticated user info and use in all controllers and services?

I'm using angularFireAuth and I want to retrieve the logged in user's info and use in all the controllers or services when the app is initial.

Currently, I used this in every controller but i having some problem.

$scope.$on("angularFireAuth:login", function(evt, user){ 
  console.log(user);
});

The callback will not call if it is not a full page load or return null when app initial.

I need some tips for how can I return the authenticated user's info so I can use when app is initial and in all the controllers and services.

Example

When in controller or services

$scope.auth.user.id will return user's ID
$scope.auth.user.name will return user's name
etc

I would start with a userService for this:

angular.module('EventBaseApp').service('userService', function userService() {
    return {
        isLogged: false,
        username: null
    }

});

And write a LoginCtrl controller:

angular.module('EventBaseApp')
  .controller('LoginCtrl', function ($scope, userService, angularFireAuth) {
    var url = "https://example.firebaseio.com";
    angularFireAuth.initialize(url, {scope: $scope, name: "user"});

    $scope.login = function() {
        angularFireAuth.login("github");

    };
    $scope.logout = function() {
        angularFireAuth.logout();
    };

    $scope.$on("angularFireAuth:login", function(evt, user) {
      userService.username = $scope.user;
      userService.isLogged = true;
    });

    $scope.$on("angularFireAuth:logout", function(evt) {
      userService.isLogged = false;
      userService.username = null;
    });
});

Inject the userService anywhere you want the user.

My app that am currently working on that uses this - https://github.com/manojlds/EventBase/blob/master/app/scripts/controllers/login.js
