I cannot find the constructor for
androidx.ui.core.LayoutNode(modifier = currentComposer.materialize(modifier), measureBlocks = measureBlocks) { childrend() }
Which is used in many base composable components. I would like to use especially the way LayzyItems using it to be able to add and remove Nodes during measurement runs.
Why is it hidden from the Public API? Or maybe i just missed something?

It's a trick of compiler plugin, this call gets replaced with composer.emit 🙂

[shikasd]

Actually it doesn't happen on current dev, they have removed it recently

[Timo Drick]

ok nice. So it will be available in the next dev release?

[shikasd]

You can call it right now actually, just follow the same pattern as they do

Leland tweeted about this recently with more details

[Timo Drick]

Interesting but it looks like that the keyword emit is also hidden.

[shikasd]

Yeah, but before that you can use just constructor as it is now, it should be compiled correctly

[Andrey Kulikov]

out of curiosity, what use case are you trying to solve?

[Timo Drick]

I do have a custom implementation of the AdapterLIst (LazyColumn/Row-Items) with more features. I am using the Layout() composable as base currently. But it is a little bit tricky to get the child nodes in sync with the measurement code. I have to add tags to the child item nodes.

Ok thank you very much guys. Android Studio show every thing red but it compiles and works. (Just replecated the Layout() composable for now.
