deleteSink method
Deletes a sink. If the sink has a unique writer_identity, then that
service account is also deleted.
Throws a http.ClientException if there were problems communicating with
the API service. Throws a ServiceException if the API method failed for
any reason.
Implementation
Future<void> deleteSink(DeleteSinkRequest request) async {
final url = Uri.https(_host, '/v2/${request.sinkName}');
await _client.delete(url);
}
