onError method

  1. @override
void onError(
  1. DioError err,
  2. ErrorInterceptorHandler handler
)

The callback will be executed on error.

If you want to continue the error , call handler.next.

If you want to complete the response with some custom data directly, you can resolve a Response object with handler.resolve and other error interceptor(s) will be skipped.

If you want to complete the response with an error message directly, you can reject a DioError object with handler.reject, and other error interceptor(s) will be skipped.

Implementation

@override
void onError(
  DioError err,
  ErrorInterceptorHandler handler,
) {
  if (level == Level.none) return handler.next(err);

  logPrint('[DIO]<-- HTTP FAILED: $err');

  return handler.next(err);
}
