AttachDetachHandler

class AttachDetachHandler

Manages dispatching attach/detach events to a set of Attachable.

For Spec Components, this will invoke OnAttached when a component is attached to the ComponentTree and OnDetached when a component is detached from the tree.

For Kotlin components, this will handle dispatching callbacks registered with the useEffect hook.
