getStorageInfo method
GetStorageInfo returns the storage info of the specified resource.
Request parameters:
resource - Required. The path of the instance to return storage info
for, in the form:
projects/{projectID}/locations/{locationID}/datasets/{datasetID}/dicomStores/{dicomStoreID}/dicomWeb/studies/{studyUID}/series/{seriesUID}/instances/{instanceUID}
Value must have pattern
^projects/\[^/\]+/locations/\[^/\]+/datasets/\[^/\]+/dicomStores/\[^/\]+/dicomWeb/studies/\[^/\]+/series/\[^/\]+/instances/\[^/\]+$.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a StorageInfo.
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<StorageInfo> getStorageInfo(
  core.String resource, {
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if ($fields != null) 'fields': [$fields],
  };
  final url_ = 'v1/' + core.Uri.encodeFull('$resource') + ':getStorageInfo';
  final response_ = await _requester.request(
    url_,
    'GET',
    queryParams: queryParams_,
  );
  return StorageInfo.fromJson(
      response_ as core.Map<core.String, core.dynamic>);
