How to clear previous user cache data in Flutter Firebase?

Question

I am facing a problem of whenever a user signs out FirebaseAuth.instance.signOut() and signs In with another account the previous user's data is visible. I have seen documentation and got an idea of clearing the cache data using FirebaseFirestore.clearPersistence(). I tried this in the signOut method but though previous user's data is still visible. Can anyone please solve my issue!

main.dart

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  FirebaseFirestore.instance.settings=Settings(
    persistenceEnabled: false,
  );
  runApp(MyApp());
} 

firebaseAuth.dart

  static logOut()async{
    await FirebaseFirestore.instance.clearPersistence();
    return  FirebaseAuth.instance.signOut();
  }

THANK YOU SO MUCH!

Solution

You probably fixed this already but I was having the same issue and what worked for me was clearing app variables when loggin out.

I created a function to clear the variables and called it right before the signOut method

can you give code example for how to clear the app variables before signout?

This works, but it seems weird that firebase been based on streams and a very accurate cache management by user, do this. Definitely the OP needs to give us more info on what was doing.
