Cards as items are invisible.

[mainrs]

I am probably missing something. I'd assume items need to have a fixed height/width to make this work. But even setting requiredHeight does not work.

LazyStaggeredGrid(columnCount = 2) {
        notes.forEach { note ->
            item {
                NoteCard(
                    modifier = Modifier.fillMaxWidth(),
                    title = note.embedded.title,
                    content = note.contents[0].value.toString(Charsets.UTF_8))
            }
        }
    }
}

@Composable
private fun NoteCard(
    modifier: Modifier = Modifier,
    title: String,
    content: String? = null,
) {
    Card(modifier = modifier) {
        Text(text = title)
        if (content != null) {
            Text(text = content)
        }
    }
}

Looks like your implementation does not get re-composed if the input data changes. I collect my state from a Kotlin Flow using collectAsState(initialState = emptyList()). The lazy grid initializes with the empty list but does not recompose if the list items change. Probably due to the fact that a simple loop is used to iterate over the items.
