onError method

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

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) {
  return handler.next(err);
}
