Anybody have any tips for converting a class to a @Composable fun? I can't quite conceptualize it and for the most part I'm writing imperative UI with compose

[Adam Powell]

got an example?

Validating text fields comes to my mind first, because I'm doing that right now. I use a class to handle most of the validation logic and I can't figure out how to convert a class to a composable. More generally, I often find myself writing a class to "separate concerns" rather than doing it the "proper" compose way.

This is a small example of how I am handling validation right now and I'm sure there is a way to do it without using class but I can't imagine it because I am stuck doing things the old way

[Adam Powell]

maybe think of it less as converting a class to a composable as extracting the state management from the presentation

[Adam Powell]

it's totally fine - even encouraged - to keep policy and state management in objects that then get passed to composables for presentation

Hmm, that makes perfect sense. I guess I will just need to start thinking about how to write it out a bit more, then. Thank you!

this seems like the kind of thing a StateHolder would be a good fit for
