list method
Lists all OauthClientCredentials in an OauthClient.
Request parameters:
parent - Required. The parent to list OauthClientCredentials for.
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/oauthClients/\[^/\]+$.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a ListOauthClientCredentialsResponse.
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<ListOauthClientCredentialsResponse> list(
  core.String parent, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$parent') + '/credentials';
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return ListOauthClientCredentialsResponse.fromJson(
    response_ as core.Map<core.String, core.dynamic>,
  );
