is there way to make constructor composable? I want pass through it data that calculates with composable function. It will always call in composable context. Can i do it somehow?

You can create a separate method which would return your result

[Adam Powell]

Yep. If you declare a top-level factory function as

@Composable
fun ButtonStyle(...) = ButtonStyle(...)

then you get the same call site characteristics and user expectations as a constructor, plus you're forced to keep a "real" constructor public, which ensures that you can create these objects outside of composition, aiding both aggregation as part of other state objects and testability

private constructor plus operator fun invoke in companion object can “simulate” invoking the constructor

[Adam Powell]

Indeed, but then you have a private constructor and a type that can only be created during composition. 🙂
