I have a flow continuously receiving from backend new values, which I transform to screen offsets for animation purposes and put in a map called markersMap:

receivedFlow.value?.let { received ->
    markersMap[received.stationId]?.offset = markersMap[received.stationId]?.nextOffset
    markersMap[received.stationId]?.nextOffset = Offset(received.x, received.y)
}

Then I have a composable looping each second over all items in markersMap, in order to create an animation from their previous offset to their next offset

@Composable
fun NativeMarkersAnimator() {
    val offsetsMap = remember {
        mutableStateMapOf<Long, Animatable<Offset,AnimationVector2D>>()
    }

    LaunchedEffect(Unit) {
        while (true) {
            markersMap.forEach { marker ->
                val targetOffset = marker.value.futureOffset
                targetOffset?.let { target ->
                    offsetsMap[marker.value.stationId] =
                        Animatable(marker.value.offset, Offset.VectorConverter)
                    offsetsMap[marker.value.stationId]?.animateTo(target, tween(900))
                }
            }
            delay(1000)
        }
    }
    //CANVAS
}

and obviously, also withinNativeMarkersAnimator, the Canvas that will recompose for rendering animations:

@Composable
fun NativeMarkersAnimator() {
    val offsetsMap = remember {
        mutableStateMapOf<Long, Animatable<Offset,AnimationVector2D>>()
    }

    // LAUNCHED EFFECT in code snippet above


    Canvas(modifier = Modifier.fillMaxSize()) {

        offsetsMap.forEach { offset ->
            val image = markersMap[offset.key]?.bitmap?.asImageBitmap()
            image?.let {
                drawImage(
                    image = image,
                    topLeft = offset.value.value
                )
            }
        }
    }
}

My issue: the values of markersMap found in LaunchedEffect are not consistent with the values received from the flow: if I get from the flow e.g. Offset(400,300), I put it into markersMap at the key x, I get an entry <x, Offset(400,300)>.

But during the Launched Effect loop I find a totally different value from the same entry, not <x,Offset(400,300)> but lets say <x, Offset(600,600)>, the value looks random or very old and it remains the same a lot, let’s say I update 20 times the entry from the flow, but from the LaunchedEffect it’s still the same (wrong) value. This means the offset anim will start from the same point a lot of times!
So the results is that animations kinda loop, starting from the same initial offset point and doing the same path again and again.

I think the issue is complex and that’s the reason chatgpt can’t help so much. Any hint would be of huge worth. Thanks in advance
