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.
Copy code
= 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
