Hey all, I'm attempting to use a state handler to update a database for Flow state transitions to Running, Failed, and Successful.  I need to use a Flow parameter result to make the update, which I can retrieve from the state result for Failed and Successful, but its not clear to me how to do this for the Running state, which has NoResultType

```
def handle_state(flow, old_state, new_state):
    def param_value_for(param_name, state):
        p = next(filter(lambda k: k.name == param_name, new_state.result.keys()))
        r = state.result[p]
        return r.result

    if new_state.is_running():
        foo = param_value_for('foo', new_state)
        print('Starting to run')
    elif new_state.is_failed():
        foo = param_value_for('foo', new_state)
        print(f'We have a failure for {foo}')
    elif new_state.is_successful():
        foo = param_value_for('foo', new_state)
        print(f'We have a success for {foo}')
```

Hey <@ULAA4BNS2> - take a look in `prefect.context` for the flow parameters:
```
p = prefect.context.get("parameters", {}).get(param_name)
```
this should be populated at the time of your flow’s state handlers being called

ah cool, thanks.  I figured there must be an easier way

Are parameters not documented here because they aren't *always* available in the context? <https://docs.prefect.io/api/0.6.0/utilities/context.html#context-2>

That’s a great question; they should always be in context during a flow run, so that’s an oversight! I’ll update

<@UKNSNMUE6> maybe we should also start populating that list with all the Cloud variables that are available as well?  Run ID, etc.

yea that’s a good idea, i’ll get that going this afternoon
