      retries: 3, // Number of retries before a failure
      retryInterval: const Duration(seconds: 1), // Interval between each retry
      retryEvaluator: (error) => error.type != DioErrorType.CANCEL && error.type != DioErrorType.RESPONSE, // Evaluating if a retry is necessary regarding the error. It is a good candidate for updating authentication token in case of a unauthorized error (be careful with concurrency though)
    )
