title: How to Route to a specific page in bottom navigation bar?
body: <p>I have 4 pages in bottom navigation bar. I am facing a problem related to route that i want to route to a specific page in bottom navigation bar  from another page?
  e.g I am going to login page and post successful login I want to route user to accountdetails(AccountSetting) but if I am selecting account setting then in that page bottom navigation bar is not showing and if I am routing to bottom nav bar here I am unable to select index of my choice. How can I select index of my choice because I don't want to make new page having bottom nav bar?</p>
