The example in the documentation shows the case where we’re controlling the values ourselves from inside the @Preview function. If I have a function that looks something like this, super simplified:

sealed interface State { object One : State; object Two : State; object Three : State }

@Composable
fun MyComp(state: State) {
  val color by animateColorAsState(when(state)){...})
  Box(modifier = Modifier.animateContentSize()) {
    when(state) {
      is One -> SomeComposable1(Modifier.height(16.dp).smth(color))
      is Two -> SomeComposable2(Modifier.height(32.dp).smth(color))
      is Three -> SomeComposable3(Modifier.height(48.dp).smth(color))
    }
  }
}

Then in order to Preview this all I can do is to pass a state object, like:

@Preview
@Composable
fun MyCompPreview() {
  val state = State.One // Changing it in an rememberInfiniteTransition doesn't work of course, it's just 3 distinct values
  MyComp(state)
}

which doesn’t allow me to use the animation inspector with it. And I don’t want to test the

SomeComposable#

in isolation either, I am interested in the

MyComp

itself and its interaction with everything else.
