createAsync method
Creates a log bucket asynchronously that can be used to store log entries.After a bucket has been created, the bucket's location cannot be changed.
request - The metadata request object.
Request parameters:
parent - Required. The resource in which to create the log bucket:
"projects/[PROJECT_ID]/locations/[LOCATION_ID]" For
example:"projects/my-project/locations/global"
Value must have pattern ^organizations/\[^/\]+/locations/\[^/\]+$.
bucketId - Required. A client-assigned identifier such as "my-bucket".
Identifiers are limited to 100 characters and can include only letters,
digits, underscores, hyphens, and periods. Bucket identifiers must start
with an alphanumeric character.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a Operation.
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<Operation> createAsync(
  LogBucket request,
  core.String parent, {
  core.String? bucketId,
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if (bucketId != null) 'bucketId': [bucketId],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'v2/' + core.Uri.encodeFull('$parent') + '/buckets:createAsync';
  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return Operation.fromJson(response_ as core.Map<core.String, core.dynamic>);
