 ## Transformer
 
-`Transformer` allows changes to the request/response data before it is sent/received to/from the server. This is only applicable for request methods 'PUT', 'POST', and 'PATCH'. Dio has already implemented a `DefaultTransformer`, and as the default `Transformer`. If you want to custom the transformation of request/response data, you can provide a `Transformer` by your self, and replace the `DefaultTransformer` by setting the `dio.transformer`.
