How to properly implement Logout with firebase on flutter

问题

It sounds stupid but I cant really properly logout of my app and that is because I use multiple FirebaseAnimatedList and route on my MaterialApp

routes: <String,WidgetBuilder>{
    '/StartAppPage':(BuildContext context)=>new StartAppPage(),
    '/LoginPage':(BuildContext context)=> new LoginPage(),
    '/HomePage':(BuildContext context)=> new HomePage)
  },

So the app checks for use and routes to HomePage or Login based on is there is a user or not.

My Home page has a FirebaseAnimatedList and on my Home page there is a Logout button that do this

await googleSignIn.signOut();
await FirebaseAuth.instance.signOut();
await FirebaseDatabase.instance.goOffline();
return Navigator.pushReplacementNamed(context, '/StartApp');

to HomePage and logout the user.

But when the other user login again the List shows data of the old user and the list is usable messing my Database

How can I properly implement this and the setPersistance is off or on makes no difference

Solution: Keep a single instance of your firebase user through the app. I recommend a global variable
