onError method

  1. @override
Future onError(
  1. DioError err
)
override

The callback will be executed on error.

If you want to resolve the request with some custom data， you can return a Response object or return dio.resolve. If you want to continue the request, return the DioError object.

Implementation

@override
Future onError(DioError err) async {
  if (_onError != null) {
    return _onError!(err);
  }
}
