Why can't we have a `spacing` parameter for the `items` in `LazyColumn`, it's very convenient.

Why can't we have a spacing parameter for the items in LazyColumn, it's very convenient.

[Zach Klippenstein (he/him) [MOD]]

You got one: verticalArrangement = spacedBy(…)

[Kyant]

But I want different items have different spacings.

If it's for different items, then I guess it's better if it is taken care for in the item section

[Jack Boswell]

I could have an item that has a Column with different sizing, but then the items in that column aren't lazy 🤔

[andylamax]

what I mean is this

LazyColumn {
  items(data) { item ->
    Item(
        modifier = Modifier.padding(
           top = when(item) {
               is ItemA -> 10.dp
               is ItemB -> 13.dp
               else     -> 5.dp
           }
        )
    )
  }
}

Because, asking to have spacing parameter on the LazyColum itself, and each item requiring a different spacing, would result into a very ugly API

[Kyant]

I meant
items(list, spacing = 8.dp) {}

[Kyant]

Or I have to use itemsIndexed with Spacer in the item, it's too duplicated

[andylamax]

LazyList(
  arrangement = Arrangement.spacedBy(8.dp)
) {
  items(list) {
    // hour code here
  }
}

Doesn't this fit your use case?

[Jack Boswell]

I think they're looking for per-region sizes

LazyList {
  items(list1, arrangement = Arrangement.spacedBy(8.dp)) {
    // hour code here
  }
  items(list2, arrangement = Arrangement.spacedBy(16.dp)) {
    // hour code here
  }
}

[andylamax]

Oooh, I see. Is that the case @Kyant?

[Kyant]

Yes, the per-items spacing

[andylamax]

oooh, if that's the case, then I agree with you, I think something can be improved there especially without ruining the API
