afterError method

@override Future<void> afterError(DioException err, ErrorInterceptorHandler handler)

Runs when Dio reports an error (network, bad response, cancel, etc.). Default forwards unchanged.

Implementation

@override
Future<void> afterError(
  DioException err,
  ErrorInterceptorHandler handler,
) async {
  if (onAfterError != null) {
    await onAfterError!(err, handler);
  } else {
    handler.next(err);
  }
}
