Observing Flows
Introduction
As described on the serialising flows, you should be able to serialise a Flow to a ConanState that suits you, and then leverage all the features of the Conan State to observe it.
We have though some mechanisms to provide you with a shortcut when observing flows
As of v1.0 we only have hooks, but we are planning to add more shortcuts to observe directly flows without having to serialise them
Hooks
useFlow
useFlow<AuthenticationState,AuthenticationFlow>(
        authentication$F, 
        setState, 
        (status, previousState) => ({
                ...previousState,
                current: status.name,
        })
);
This hook receives 
a flow
the method to set the state for this component
a function that returns the new state and that takes
the status information that has just been updated
the previous state
useFlowStatus
useFlowStatus<AuthenticationState, AuthenticationFlow,"authenticating">(
        authentication$F, 
        "authenticating", 
        setState, 
        (status, previousState) => ({
                ...previousState,
                currentUser: status[0]
         }
 ));
This hook receives 
a flow
the name of the status to subscribe to
the method to set the state for this component
a function that returns the new state and that takes
the state information that has just been updated
the previous state
