Implementation

@override

  var url = baseUrl.replace(
      path: _p.join(baseUrl.path, id.toString()),
      queryParameters: _buildQuery(params));

  var response =
      await app.sendUnstreamed('POST', url, _writeHeaders, makeBody(data));

  try {
    if (_invalid(response)) {
      if (_onUpdated.hasListener) {
        _onUpdated.addError(failure(response));
      } else {
        throw failure(response);
      }
    }

    var r = deserialize(json.decode(response.body));
    _onUpdated.add(r);
    return r;

    } else {
