delete method
Deletes a property.
Request parameters:
fileId - The ID of the file.
propertyKey - The key of the property.
visibility - The visibility of the property.
$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.
Implementation
async.Future<void> delete(
  core.String fileId,
  core.String propertyKey, {
  core.String? visibility,
  core.String? $fields,
}) async {
  final queryParams_ = <core.String, core.List<core.String>>{
    if (visibility != null) 'visibility': [visibility],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'files/' +
      commons.escapeVariable('$fileId') +
      '/properties/' +
      commons.escapeVariable('$propertyKey');
  await _requester.request(
    url_,
    'DELETE',
    queryParams: queryParams_,
    downloadOptions: null,
  );
