as well as ```IconButton(onClick = scaffoldStateClick())``` gives me: `The feature "unit conversion"...

as well as

IconButton(onClick = scaffoldStateClick())

gives me:
The feature "unit conversion" is disabled

am a bit clueless on how to fix both...

I can't see your definition of scaffoldStateClick(), but two questions:
(1) the onClick parameter expects a lambda/function, but you are INVOKING scaffoldStateClick(), not passing it as a parameter. Did you mean ::scaffoldStateClick or scaffoldStateClick ?
(2) If you did intend to invoke scaffoldStateClick() and it returns a lambda, are you sure the returned lambda is of type ()->Unit ?

[Dirk Hoffmann]

fun scaffoldStateClick() = {
    val adScaffoldState = ADState.ADScaffoldState
    if (adScaffoldState.drawerState().isClosed) {
        adScaffoldState.drawerState().open()
    } else {
        adScaffoldState.drawerState().close()
    }
}

[Dirk Hoffmann]

ADState.ADScaffoldState is a singleton Object that keeps all my states and provides methods on them
(don't know if that is good design ... is it??)

[jim]

You should pass your ADScaffoldState instance as a parameter, not use a singleton object. You always want to develop your widgets as self-contained reusable chunks that are pure functional transforms of their parameters. Relying on a global singleton violates several of those principles.

Also, your scaffoldStateClick() does not return a unit lambda, so that's why you're getting a type error. You probably want your code to be more like IconButton(onClick = { scaffoldStateClick(adScaffoldState) })
