In my multiplatform project I cant seem to find a solution for LocalOverscrollConfiguration. It shows up as unresolved. I want to disable the overscroll effect for lazycolumn.

Ah thanks. That's unfortunate. Is there a solution for this at all then?

[ephemient]

you could make an expect-actual function that configures overscroll on android and does nothing on desktop, for example

I am building for android and ios only, and I simply want to disable the overscroll effect. Would you be able to point me in the right direction on how to do that?

for iOS it appears there is only a global configuration, so you need to invoke https://github.com/JetBrains/compose-multiplatform-core/blob/jb-main/compose/foundation/foundation/src/uikitMain/kotlin/androidx/compose/foundation/gestures/UikitScrollable.uikit.kt#L34-L43 during app startup

so something like

// common
expect fun disableUiKitOverscroll()
expect fun provideNullAndroidOverscrollConfiguration(): Array<ProvidedValue<*>>

// iOS
@OptIn(ExperimentalFoundationApi::class)
actual fun disableUiKitOverscroll() = optOutOfCupertinoOverscroll()
actual fun provideNullAndroidOverscrollConfiguration() = emptyArray<ProvidedValue<*>>()

// Android
actual fun disableUiKitOverscroll() {}
@OptIn(ExperimentalFoundationApi::class)
actual fun provideNullAndroidOverscrollConfiguration(): Array<ProvidedValue<*>> = arrayOf(
    LocalOverscrollConfiguration provides null
)

// usage
fun main() {
    disableUiKitOverscroll()
    ...
}
@Composable
fun Main() {
    CompositionLocalProvider(*provideNullAndroidOverscrollConfiguration()) {
        ...
    }
}

This is gold. Thank you so much. Giving it a shot now.
