I want to render a view outside tabs in ionic-starter-tabs

1

I want to render a view outside tabs in ionic-starter-tabs, but it gives a white screen.

I am using latest cordova, latest ionic.

Using these router configs.

.state('verify.number', {
        url: '/verify-number',
        templateUrl: 'src/registration/verify-number.html',
        controller: 'VerifyNumberCtrl'
    })
    
    .state('tab', {
        url: "/tab",
        abstract: true,
        templateUrl: "src/tabs.html"
    })

Any help would be highly appreciated.
