Why FirebaseAuth currentUser() is kept after uninstall the app?

I am trying to get the login state of the user in Flutter, whenever I run my application for the first time (Only when I uninstall and reinstall the app) following code return a user.

I already tried to get the user from whenComplete and then both return the same.

 FirebaseAuth _firebaseAuth = FirebaseAuth.instance;    
 FirebaseUser user = await _firebaseAuth.currentUser();
 return user;

returned user is a platform user from my android device, and if I reload my app after install user will be removed.

Edit:

  1. I already tried all the steps in https://stackoverflow.com/a/48660787/979653
  2. I removed all the users from my Firebase
  3. My app showing a user id which is not in my Firebase.

Funny thing is minimizing the app removes the unknown user.

That happens because data will persist anyways offline in some cases regardless of the app being deleted or not, and thus, your previous Firebase user.

Referring to this answer:

It's because Android 6 has automatic backup. You need to tune android:allowBackup and android:fullBackupContent in your manifest tag if you don't want your data backed up or if you want to include or exclude some resources. It's not a bug.

So basically, add android:allowBackup="false" and android:fullBackupContent="false" in manifest.xml and you should be fine.
