has anybody tried using this from Kotlin? https://www.npmjs.com/package/react-window-infinite-loader in the example the following code is used: {({ onItemsRendered, ref }) => ( is there a way to express that in Kotlin JS?

[Alex Ostrovsky]

I think what it's saying is that there's a function which takes an Object with keys "onItemsRendered" and "ref", and this function is somehow passed to the parent InfiniteLoader. in Kotlin, how would be pass that function to the parent InfiniteLoader, is there some attribute that would be set?

You can use “options” to solve this problem

[turansky]

external interface ChildrenOptions {
    onItemsRendered: Function<*>
    ref: RRef
}

// ...
children: (options: ChildrenOptions) -> ???

[Alex Ostrovsky]

oh interesting, I see there is fun <T> RBuilder.children(value: T) on RComponent, is that it or is there some other "children"?

[Alex Ostrovsky]

or would "children" be declared as an attribute of the InfiniteLoader wrapper?

[turansky]

Props.children declared here without strict typization

[Alex Ostrovsky]

oh I see, that's great, thanks for your help!

In future we will have less Any , dynamic props in wrappers. 🙂

In common case Any & dynamic = TODO

[turansky]

children can be strict
