Is there an empty element in compose?

Spacer: https://developer.android.com/reference/kotlin/androidx/compose/foundation/layout/package-summary#Spacer(androidx.compose.ui.Modifier)

Not sure if it fits what you want but it the seems the most "empty" element is the Box

[adauguet]

That is what I had in mind

I guess there are several solutions

[r4phab]

Maybe the Spacer ?

[adauguet]

So Spacer(Modifier)

[nitrog42]

you can just check the code of both,
Box :

@Composable
fun Box(modifier: Modifier) {
    Layout({}, measurePolicy = EmptyBoxMeasurePolicy, modifier = modifier)
}

Spacer:

@Composable
fun Spacer(modifier: Modifier) {
    Layout({}, modifier) { _, constraints ->
        with(constraints) {
            val width = if (hasFixedWidth) maxWidth else 0
            val height = if (hasFixedHeight) maxHeight else 0
            layout(width, height) {}
        }
    }
}
