 The manager delegates instantiating of config flow handlers to this async callback. This allows the parent of the manager to define their own way of finding handlers and preparing a handler for instantiation. For example, in the case of the config entry manager, it will make sure that the dependencies and requirements are setup.
 
 ```python
-async def async_finish_flow(context, result)
+async def async_finish_flow(flow, result)
 ```

 ## Flow Handler
 
 Flow handlers will handle a single flow. A flow contains one or more steps. When a flow is instantiated, the `FlowHandler.init_step` step will be called. Each step has three different possible results: "Show Form", "Abort" and "Create Entry".
