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 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.
