patch method
Makes changes to a Product resource.
Only the display_name, description, and labels fields can be updated
right now. If labels are updated, the change will not be reflected in
queries until the next index time. Possible errors: * Returns NOT_FOUND if
the Product does not exist. * Returns INVALID_ARGUMENT if display_name is
present in update_mask but is missing from the request or longer than 4096
characters. * Returns INVALID_ARGUMENT if description is present in
update_mask but is longer than 4096 characters. * Returns INVALID_ARGUMENT
if product_category is present in update_mask.
request - The metadata request object.
Request parameters:
name - The resource name of the product. Format is:
projects/PROJECT_ID/locations/LOC_ID/products/PRODUCT_ID. This field is
ignored when creating a product.
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/products/\[^/\]+$.
updateMask - The FieldMask that specifies which fields to update. If
update_mask isn't specified, all mutable fields are to be updated. Valid
mask paths include product_labels, display_name, and description.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a Product.
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<Product> patch(
  Product request,
  core.String name, {
  core.String? updateMask,
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if (updateMask != null) 'updateMask': [updateMask],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$name');
  final response_ = await _requester.request(
    url_,
    'PATCH',
    body: body_,
    queryParams: queryParams_,
  );
  return Product.fromJson(response_ as core.Map<core.String, core.dynamic>);
