Can we add extension function like

SpacedBy(4.dp) { Content() }

for

ColumnScope

and

RowScope

?

Is Row

horizontalArrangement = Arrangement.spacedBy(4.dp)

not sufficient?

It is available only when we call Columns and Rows functions directly But when we use material components we can pass composable content with ColumnsScope or RowScope. Here we can’t use it

shouldnt the arrangement be set by the parent anyways?

fun RowScope.MyComposable(){

Might work for what youre trying to accomplish?

It won’t

isn't padding enough for what you want? Or do you need custom spacing per item that handles both first and last position?
