how to redirect user to logout page when token or refresh token expired using bloc in flutter

This is my base repository where it gets the data from the bloc I want to redirect the user to a custom page like logout when the token expires or refresh token expire. I change pages, in bloc consumer or bloc listener but in this case, this is stupid work because I should replace bloc consumer with another bloc method everywhere I request to the server

 @override
  Future<Map<String, dynamic>> get(String url) async {
    // Uri newUrl = Uri.parse(baseUrl + url);
    var newUrl = baseUrl + url;
    dio.Response response;
    try {
      // x.interceptors.add(dio.InterceptorsWrapper(
      //   onError: (e, handler) {
      //     if(e.response!.statusCode == 401)
      //         redirect user to custom page
      //   },
      // ));
      response = await dio.Dio()
          .get(newUrl, options: dio.Options(headers: headersList))
          .timeout(duration);
      var result = _processResponse(response);
      if (result.runtimeType.toString().toLowerCase() == 'string') {
        return <String, String>{'key': result};
      }
      return result;
    } on SocketException {
      throw FetchDataException('internetConnection');
    } on TimeoutException {
      throw ApiNotRespondingException('api not found ');
    } on Exception catch (e) {
      var response = e as dio.DioError;
      print(e.toString());
      throw _handleError(response);
    }
  }
