                children: [
                    {
                        component: {
                            name: 'demoApplication.NewsListScreen',  //tab component
                        }
                    }
                ],
                options: {           // try options for topbar and bottom tabs       
                    bottomTab: {
                        text: 'Users',
                        icon: require('../../assets/images/two.png')
                    },
