Can you remember {} a when statement?

I'm trying something like this

remember{
   when (someValue) {
       optionA -> {
           doSomething()

but I get an error of "remember calls must not return Unit"

I think you want DisposableEffect .

Since you don't seem to `remember`ing anything.

Hm. Thanks for making me think harder here. I suppose you're right. And I suppose I need to read the sideEffects docs for like the 10th time. Something with sideeffects just doesn't click for me. 😭

[Colton Idle]

This first line in the docs always gets me. "Composables should be side-effect free." I think I also picked up this habbit from @jim as I'm allergic to CompositionLocals and SideEffects in my code. Any time I see them I try to get rid of them.

Could the first sentence in the docs be interpreted as "Composable should typically be free of side-effects, but they are necessary in some cases"
?

[Dominaezzz]

Well, maybe it should say. Wrapping your side effects with *Effect removes the side effect from the composable.

[Dominaezzz]

Or rather, there should no side effects ran during composition.

I think that is covered by "should" (see: https://www.ietf.org/rfc/rfc2119.txt)

Btw, @Colton Idle, your allergy is probably a good thing. Your code will be much better than everyone else's as a result 😇

[Colton Idle]

ooof. got hit with the rfc link. 😂
@jim appreciate it though. I guess like I said, Im just very "against" having these in my app so I typically try other things first. In this case... it looks like its necessarythough.

@Dominaezzz thanks for your help. I went for LaunchedEffect and it did what I expected. 🙏
