how to position floatbutton to the left in jetpack compose (cutout)

I want to create animated bottomAppBar in jetpack compose (something like image) but Fab position in jetpack compose is only center or end and i need to move FAB to left at least, my code is :

@Composable
fun BottomBarSample() {
    Scaffold(
        floatingActionButton = {
            FloatingActionButton(
                shape = CircleShape,
                onClick = {},
            ) {
                Icon(imageVector = Icons.Filled.Add, contentDescription = "icon")
            }
        },
        floatingActionButtonPosition = FabPosition.End,
        isFloatingActionButtonDocked = true,
        bottomBar = {
            BottomAppBar(backgroundColor = Color.Cyan, cutoutShape = CircleShape) {

            }
        }
    
    ){
        //body
    }
}

>Solution :

I guess this is not a good approach as we are changing the layout direction, but I had this issue before and I just modified the layout direction from LTR to RTL.

CompositionLocalProvider(LocalLayoutDirection provides LayoutDirection.Rtl ) {
       BottomBarSample()
}
