Question

I m trying to implement a modified WithConstraint Linter says NodeLayout call doesn t take any argument code compiles just fine but it is not executed I guess there is an internal NodeLayout Composable function which refers to the NodeLayout class but I cannot find it What is the proper way to use NodeLayout in my own code

Andrey Kulikov · Answer

hey yes currently we emit LayoutNode in a bit different way not like a composable function and this code is currently being refactored and will be changed in the nearest future to be more understandable I am really curious what use case are you trying to solve with your own `WithConstraints` as were planning to make such things simpler soon

I m trying to create a scroller with automatic anchor points for every children I m adding the position of every children to WithConstraintsScope Is there a better way to do that

thanks for replying btw

Could you just provide an Ambient to register the positions with

Octave Decaux · Answer

Thanks for the suggestion My understanding was that Ambient is more of a downstream mechanism but I guess I just learned something I m really glad this channel exists

Andrey Kulikov · Answer

basically there are no good ways of solving this yet creating your own WithConstraints doesnt really help here as you want to have children sizes in the composable child block of withconstraints but this composable blocks defines the children so for the moment of the invoking the WithConstraints block there are no children yet not saying that they are not yet measured what you probably want is a to be added in the future feature for `LazyColumnItems` renamed `AdapterList` where we will have a functionality to scroll to the second item and so on

Andrey Kulikov · Answer

something similar is solved in `TabRow` where we scroll to the tapped `Tab` but this code is also not super reusable at the moment

I think I misunderstood what you are trying to do

Octave Decaux · Answer

Ok thanks for taking the time guys

Octave Decaux · Answer

I just had a look at TabRow This does indeed feels like a hack but it will do for now ``` Delay indicator composition until we know tab positions if tabPositions isNotEmpty indicatorContainer tabPositions ```

Hey just to let you know that I eventually found a solution by bolting together different things mainly <https gist github com odecaux 808c71b646c0a170cfeb2cb0686858e0>
