list method
Lists operations that match the specified filter in the request.
If the server doesn't support this method, it returns UNIMPLEMENTED.
Request parameters:
name - The name of the operation's parent resource.
Value must have pattern ^operations$.
filter - The standard list filter.
pageSize - The standard list page size.
pageToken - The standard list page token.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListOperationsResponse.
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

  core.String name, {
  core.String? filter,
  core.int? pageSize,
  core.String? pageToken,
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if (filter != null) 'filter': [filter],
    if (pageSize != null) 'pageSize': ['${pageSize}'],
    if (pageToken != null) 'pageToken': [pageToken],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$name');
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return ListOperationsResponse.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
