list method Null safety

Future<ListEnvironmentsResponse> list(
  1. String parent,
  2. {int? pageSize,
  3. String? pageToken,
  4. String? $fields}
)

List environments.

Request parameters:

parent - List environments in the given project and location, in the form: "projects/{projectId}/locations/{locationId}" Value must have pattern ^projects/\[^/\]+/locations/\[^/\]+$.

pageSize - The maximum number of environments to return.

pageToken - The next_page_token value returned from a previous List request, if any.

$fields - Selector specifying which fields to include in a partial response.

Completes with a ListEnvironmentsResponse.

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<ListEnvironmentsResponse> list(
  core.String parent, {
  core.int? pageSize,
  core.String? pageToken,
  core.String? $fields,
}) async {
  final _queryParams = <core.String, core.List<core.String>>{
    if (pageSize != null) 'pageSize': ['${pageSize}'],
    if (pageToken != null) 'pageToken': [pageToken],
    if ($fields != null) 'fields': [$fields],
  };

  final _url = 'v1/' + core.Uri.encodeFull('$parent') + '/environments';

  final _response = await _requester.request(
    _url,
    'GET',
    queryParams: _queryParams,
  );
  return ListEnvironmentsResponse.fromJson(
      _response as core.Map<core.String, core.dynamic>);
