class_docstr: Base class for any frontend that gets exposed by LightningFlows.
  
  The flow attribute will be set by the app while bootstrapping.
docstr: Stop the process that was started with :meth:`start_server` so the App can shut down.
  
  This method gets called when the LightningApp terminates.
  
  Example:
  
      .. code-block:: python
  
          def stop_server(self):
              self._process.kill()
