in Kotlin the Observer { } lambda gives you param it, you can rename it as you want and use. by default data will be available with it.something() etc...

JAVA:

... new Observer {
  void onChanged(User user){
     user.something()
  }
}

KOTLIN

... object : Observer {
   fun onChanged(user: User?){
        user.something()
   }
}

OR

... Observer {
   it.something()
}

you can rename it to whatever you want like

... Observer { myUser ->
   myUser.something()
}
