delete method
Deletes a policy.
This action is permanent.
Request parameters:
name - Required. The resource name of the policy to delete. Format:
policies/{attachment_point}/denypolicies/{policy_id} Use the URL-encoded
full resource name, which means that the forward-slash character, /,
must be written as %2F. For example,
policies/cloudresourcemanager.googleapis.com%2Fprojects%2Fmy-project/denypolicies/my-policy.
For organizations and folders, use the numeric ID in the full resource
name. For projects, you can use the alphanumeric or the numeric ID.
Value must have pattern ^policies/\[^/\]+/\[^/\]+/\[^/\]+$.
etag - Optional. The expected etag of the policy to delete. If the
value does not match the value that is stored in IAM, the request fails
with a 409 error code and ABORTED status. If you omit this field, the
policy is deleted regardless of its current etag.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a GoogleLongrunningOperation.
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<GoogleLongrunningOperation> delete(
  core.String name, {
  core.String? etag,
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if (etag != null) 'etag': [etag],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v2/' + core.Uri.encodeFull('$name');
  final response_ = await _requester.request(
    url_,
    'DELETE',
    queryParams: queryParams_,
  );
  return GoogleLongrunningOperation.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
