here is controllers.js

angular.module(‘app.controllers’, [])

/**

*/
.controller(‘AppCtrl’, function ($scope, $state, $ionicPopup, AuthService, AUTH_EVENTS,$ionicPlatform,$ionicLoading, $compile, $cordovaGeolocation,GetDeviceInfo,CurrentLocation) {

   console.log("app controller");
  
    $scope.username = AuthService.username();
    
    
    $scope.$on(AUTH_EVENTS.notAuthenticated, function(event) {
        AuthService.logout();
    });
    
    $scope.setCurrentUsername = function(name) {
        $scope.username = name;
    };
   
});

/**************************************************/

this is my index.html

<body ng-app="app" ng-controller="AppCtrl">
    <ion-nav-view></ion-nav-view>
</body>

/*******************************************/
this is app.js file

.config(function($stateProvider, $urlRouterProvider,USER_ROLES) {
    $stateProvider

        .state('home', {
            url: "/home",
            templateUrl: "templates/home.html",
            controller: 'AppCtrl'
        })
        .state('login', {
            url: "/login",
            controller: 'LoginCtrl',
            templateUrl: "templates/login.html"
        })
        .state('main', {
            url: "/main",
            controller: 'MainCtrl',
            templateUrl: "templates/main.html"
        });

    // if none of the above states are matched, use this as the fallback
    $urlRouterProvider.otherwise('/main');
})

Dont’ depend on Auto Hide for the splashscreen, and make it
yourself at the end of authentication function.

For iOS:

<preference name="AutoHideSplashScreen" value="false" />

For Android:
set a large number for the splash screen delay time, like 1 minute

The command to hide for both:

navigator.splashscreen.hide()

or

$cordovaSplashscreen.hide();

I hope thats help
Good Luck
