    } on FirebaseAuthException catch (e) {
      change (e.code) {
        case 'account-exists-with-different-credential':
          _errorCode="You have already got an account with us. Use appropriate supplier (Apple)";
          _hasError = true;
          notifyListeners();
          break;

        case 'not chosen':
