I'm having some issues using the
Popup
composable with the
AnimatedVisibility
composable. I am using
PopupPositionProvider
to determine where to anchor my popup in relation to the parent, and only rendering the popup inside of a conditional statement. My issue is, when I replace my standard
if(...)
with the
AnimatedVisibility
composable as the parent of my popup, the position provider stops working. I think this is because the parent has changed from the original ( I was using
Box
) to the
AnimatedVisibility
composable. Is there a way I can guarantee the
AnimatedVisibility
parent to fit the same size parameters as its own parent? I would think that adding some IntrinsicSize modification or a fillMaxSize param would fix this, but the popup still is not positioned where I want it to be
here is the one that I would expect to behave the same as the if, but breaks

fun CustomTooltip(
    parentComposable: @Composable () -> Unit,
    tooltipContent: @Composable () -> Unit,
    showTooltip: Boolean,
    popupPositionProvider: CustomPopupPositionProvider,
    modifier: Modifier = Modifier
) {
    Box(modifier) {
        parentComposable()
        AnimatedVisibility(visible = showTooltip) {
            Popup(popupPositionProvider = popupPositionProvider) {
                tooltipContent()
            }
        }
    }
}


here is the original that behaves properly and positions to the correct side of the parent composable

fun CustomTooltip(
    parentComposable: @Composable () -> Unit,
    tooltipContent: @Composable () -> Unit,
    showTooltip: Boolean,
    popupPositionProvider: CustomPopupPositionProvider,
    modifier: Modifier = Modifier
) {
    Box(modifier) {
        parentComposable()
        if (showTooltip) {
            Popup(popupPositionProvider = popupPositionProvider) {
                tooltipContent()
            }
        }
    }
}
how the bottom one renders
how the top one renders (the expected behavior)

Since
Popup
renders its content in a separate window,
AnimatedVisibility
outside
Popup
has no effect on the content of the popup. If you want to animate the content, put
AnimatedVisibility
inside
Popup
.

Hm, I tried doing that but had an issue where I cannot get the animated visibility to behave as expected. I think it has something to do with how the popup only will appear in a conditional field, and
AnimatedVisibility
is also controlled by a boolean (therefore is always true within the conditional that shows the
Popup
). I even tried setting a timer on the
AnimatedVisibility
enable toggle so it would explicitly occur after the first if statement, but that still does not do the fade properly
var animateVisibility by remember { mutableStateOf(false) }
    val coroutineScope = rememberCoroutineScope()
    coroutineScope.launch {
        delay(500)
        animateVisibility = true
    }
    Box(modifier) {
        parentComposable()
        if (showTooltip) {
            Popup(popupPositionProvider = popupPositionProvider) {
                AnimatedVisibility(
                    visible = animateVisibility,
                    enter = fadeIn(
                        // Fade in with the initial alpha of 0.3f.
                        initialAlpha = 0f,
                        animationSpec = TweenSpec(durationMillis = 2000)
                    )
                ) {
                    tooltipContent()
                }
            }
        }
    }
this is the animated within the conditional I would expect to work but does not

You can use
AnimatedVisibility(
    visibleState = remember { MutableTransitionState(false).apply { targetState = true } }
)
