You can either type the address directly at that line or you can change the value of $login_redirect = get_dashboard_profile_link(); (at line 265).
This change will affect all the logins systems(not only the widget one). If you want only for widget one you need to clone and them modify (in control.js) the function wpestate_login_wd . The function is at line 1118 and for widget is called at line 1107.
Thanks you and good luck
