problem with Accompanist navigation animations. `expandIn` and `shrinkOut` always expand in/shrink to top left corner. setting `expandFrom`/`shrinkTowards` has no effect and default value for those two is `Alignment = Alignment.BottomEnd`.

Probably will need some code to really tell what's wrong here. I've used it briefly and didn't have any issues.

did you use expand and shrink animations?

Have you tried adding `fillMaxSize()` to `AnimatedNavHost`? See discussion here:

For the `Alignment.BottomEnd`, we'll need to support the content alignment on the `AnimatedHost` level to align the incoming/outgoing content to the bottom end when that content is smaller than parent.

<@UNH9ZT3NZ> I have and than it launches from the center. center is the default when `AnimatedNavHost` has `modifier.fillMaxSize()` added to it

Yea, center is where the child would be placed by default in Box. To fully control where the child is when it's smaller than parent, we'll have to support `contentAlignment` .

Out of curiosity, is there a specific effect you are trying to achieve? :slightly_smiling_face:

Btw, `contentAlignment` is support in `AnimatedContent`, which is what `AnimatedNavHost` uses under the hood.  If the visual effect you are going for can't be achieved w/ AnimatedContent, please let us know so we can add support for it.

I don’t need anything special I just used plain `expandIn` and `shrinkOut` as `enterTransition` and `exitTransition` and it’s not responding to `expandFrom` nor `shrinkTowards` `contentAlignment` parameter. that’s it

what am confused about is: are you saying that `contentAlignment` *will* be fully supported soon or it *is* fully supported now?

`expandFrom` and `shrinkTowards` refers to the clipped the content. It defines which part of the content to reveal first/last when clipped. `contentAlignment` defines the *positioning* of the clipped content in parent.

`contentAlignment` is supported in the level below `AnimatedHost` (i.e. AnimatedContent), but not surfaced in AnimatedHost. That's why I was suggesting trying out `AnimatedContent` and see whether it does what you want. If not, we can add support in AnimatedContent and surface that through AnimatedHost.
