Is there a way to know if a `stickyHeader` inside a `LazyColumn` is at the top?

Is there a way to know if a stickyHeader inside a LazyColumn is at the top?

[andrew]

I have a function for this, if you bear with me a few moments I can copy it over from my personal laptop

(on my work one at the moment)

Any luck? 😄

We can only assume his work computer consumed him, not wanting him to touch another computer. Work computers are sneaky like that sometimes 💀

[andrew]

My work computer was sneaky like this

[andrew]

It did consume me because someone broke a change at work that I had to track down 🙈

[andrew]

I did however, make it out unscathed after the work computer had, in fact, consumed me 😛

[andrew]

@Composable
fun rememberStickyHeaderActive(state: LazyListState, key: Any): State<Boolean> = remember(state) {
    derivedStateOf {
        val items = state.layoutInfo.visibleItemsInfo
        val header = items.getOrNull(0) ?: return@derivedStateOf false
        val item = items.getOrNull(1) ?: return@derivedStateOf false

        header.key == key && item.offset < header.size
    }
}

Sorry for the wait, here you go! You can probably easily make an extension function that provides this for within a sticky header without manually calling it

That's cool! Thank you! With this actually thinking to make a stickyHeader(state) { isSticky: Boolean -> } . I'll try to see if it workls later
