Implementation

    var querySnapshot = await FirebaseFirestore.instance.collection("listusers").doc(user.uid).get();
    if (!querySnapshot.exists) {
      logout();
      return stringUserNotFound; /// User not found
    }

    var t = querySnapshot.data()!["visible"];
    if (t != null)
      if (!t){
        dprint("User not visible. Don't enter...");
        logout();
        return stringUserDisabled; /// "User is disabled. Connect to Administrator for more information.",
      }

    if (_remember)
      localSettings.saveLogin(email, pass, "email");
    else

  }catch(ex){
