We use `onExited` (which is a `transition` prop) in `Grow` to do some post processing to the data structure that contains the faded element

Would be used like: ``` // Loop through each post Grow { `in` = state.postIdToRemove != news.id asDynamic().onExited = { if (state.postIdToRemove == news.id) { setState { postIdToRemove = null...

@piacenti Have a look at our project [CampusQR](https://github.com/studoverse/campus-qr) where we use class components with the new kotlin wrappers.

I was thinking the same but apparently they want to push people towards using function components. Not perfect to have this code in every project, but since it only changes...

Love the initiative since it lowers the entry barrier! @santansarah
