Some views before arriving to the slide menu

hello. I want to create an app with side menu. but I would like to have a login page before the user arrives on the side menu.
so I used "ionic start myApp sidemenu"
and on the app.js, I created a new state with a new url, templateUrl and controller.
the problem that I have is that when I go from “login” state to “app.playlists” state, I have no transitions.
why is that?
