What should I do if I want to create a custom modifier which will be stateful (composed) and that state depends on the size of the composable that it is attached to. For example, initial state is going to have 50 random objects if size is smaller than a threshold, 100 objects if it is larger.

currently, I'm just starting with a nullable state in composed and then initializing that state after first call to drawBehind modifier.

= composed {
  var state by remeber { ... }
  drawBehind {
    if(state.value == null) {
      state.value = init(size)  
    }
  }
}

Better yet, using layout modifier to initialize the state according to the size instead of drawBehind makes more sense.

Yep. I think we added an onSizeChanged modifier for cases like this too

and that was exactly what I was looking for, thanks 🙂
