Hi, there is an api for animating lazy lists:

Modifier.animateItemPlacement

, does anybody know if there is any api/approach for regular Row/Column? I’m aware of

AnimatedContent

but couldn’t make it work after a quick prototyping session

Sorry, I don't get it. Could you please explain more detail you want to achieve?

I have some variable amount of

children

composables that I render in a

Row

. I want to animate item addition/removal as

children

Can you provide me some example code and image?

Row {
  children.forEach { child->
      child.Ui()
  }
}

I don’t have an image of that, but essentially

children

is a

State<List<Component>>

where Component is :

interface Component {
    
    @Composable
    fun Ui()
}

when

children

change, the row updates but there is no addition/removal animation (which is expected since Row/Column don’t support that out of the box)
