Showing white blank page before navigating from Login page to MasterDetailpage in Xamarin Form

Hi, I'm working on app in Xamarin form where I need to login first in login page , then if succeed will it navigate to master detail page. I able to achieved it but when navigating from Login page to masterdetail page, it show <1second white blank page in between the navigation. Is that any way to make it navigate more faster without showing the white page? I'm using the masterdetail (https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/navigation/master-detail-page) page template provide by the Xamarin form.
Below show how I navigate between the pages.

      MainPage = new LoginPage();
      Application.Current.MainPage = new MasterDetailPage();
