transformRequest method
Transform a request into a signed version of the request. This is done last after the transforms on the body of a request. The returned object can be anything, but must be serializable to CBOR.
Implementation
@override
Future<Map<String, dynamic>> transformRequest(HttpAgentRequest request) {
return Future.value({
...request.toJson(),
'body': {'content': request.body.toJson()},
});
}
