Hey everyone! Just like you can do class-based Tasks, are you able to do class-based workflows? With Prefect Orion introducing the

@flow

decorator, I'm guessing this will be possible, but don't see any docs on it.

Hey @Jack Sundberg, have you seen this thread?

Hey @Kevin Kho, I hadn't seen that thread so thanks for linking it. My use-case looks pretty similar -- but my code isn't based on sklearn. Can I make a suggestion for letting users implement a feature like this?

But are you holding some state that has to be passed from flow to flow>?

Nope, it's stateless. All class attributes are immutable

I dont know if it’s possible to implement this while restricting the passing of state. You could open the feature request though and see what the core devs say

Hmm alright. I'm going to and open a github issue for this to float the idea. Thanks for the quick responses!

@Kevin Kho I opened a pull request for this. If you or some of the core devs could give feedback on whether this is possible, I'd appreciate it! https://github.com/PrefectHQ/prefect/issues/5689

Ah ok this is a bit different from my interpretation, but we’ll see what they say
