HttpStandardTransformer class

Standard response transformer

REST-Api directly returns the data structure, not package like HttpClassicTransformer.

var http = Http.getInstances(HttpBaseOptions({
  name: 'defaultApi',
  baseUrl: 'http://domain.com/api/v1',
  transformer: HttpStandardTransformer(
    errorCodeKey: 'code',
    errorMessageKey: 'message',
    errorDataKey: 'data',
  ),
}));
var res = await http.get('/users');
print(res.data); // "res.data" in "response.data" for Dio

Using the HTTP statuscode to determine if an error has occurred, the error is structured as follows:

{
  code: <int>,
  message: <String>,
  data: <AnyType>
}

HttpError will be thrown when an error occurs.
