get method
Gets the latest state of a long-running operation.
Clients can use this method to poll the operation result at intervals as recommended by the API service.
Request parameters:
name - The name of the operation resource.
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/operations/\[^/\]+$.
$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_1.Client completes with an error when making a REST
call, this method will complete with the same error.
Implementation
async.Future<Operation> get(
  core.String name, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$name');
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return Operation.fromJson(response_ as core.Map<core.String, core.dynamic>);
