I'm converting an android app slowly to kmp compose ios. I have this composable that I'm not sure what to do because of the @DrawableRes image.

@Composable
fun MyButtonToggleable(
    modifier: Modifier,
    onClick: () -> Unit,
    text: String,
    toggle: Boolean = false,
    @DrawableRes image: Int? = null
) {
Image(painterResource(id = image), null)

I guess my two questions are:
1. Is there a way to bring that annotation over into kmp? seems to be android specific?
2. painterResource isn't available?

Compose iOS has its own mechanism for providing drawables. Until very recently it used to be "stringly typed". A very recent beta of CMP 1.6 has introduced compile time safety similar to Android's R class.

I'm on mobile right now but if you search in the Compose repo you'll find examples for both

If you create a new KMP project using the online wizard it creates a screen with the Compose logo animation. That one already demonstrates how to use drawables in CMP.

If it’s a vector xml there is a handy tool you can covert to true compose vector that works on any platform.

The annotations not really Android specific itself, but androidx annotations only targetting Android I think. Also not really anything special about them, just regular Ints used 🙂
To make it easier migrate to KMP I recommend creating new like ImageResource, TextResource, DimensionResource etc. Regular sealed classes/interfaces.
And then resolve the image in this case only when needed.
Then you can delegate it one way in Android and another way in iOS as of example.
As @curioustechizen mentioned compose multiplatform offers a component resources, solving this. WHere also painterResource exist but for DrawableResource class Jetbrains provide in their plugin.
