create method
Creates a service, and returns the new service.
request - The metadata request object.
Request parameters:
parent - Required. The resource name of the namespace this service will
belong to.
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/namespaces/\[^/\]+$.
serviceId - Required. The Resource ID must be 1-63 characters long, and
comply with RFC1035. Specifically, the name must be 1-63 characters long
and match the regular expression [a-z](?:[-a-z0-9]{0,61}[a-z0-9])? which
means the first character must be a lowercase letter, and all following
characters must be a dash, lowercase letter, or digit, except the last
character, which cannot be a dash.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a Service.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
Implementation
async.Future<Service> create(
  Service request,
  core.String parent, {
  core.String? serviceId,
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if (serviceId != null) 'serviceId': [serviceId],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$parent') + '/services';
  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return Service.fromJson(response_ as core.Map<core.String, core.dynamic>);
