Navigation animation causes content to not invalidate about decompose

[arkivanov]

Thanks for reporting the issue. How do you specify the animation exactly? Can show some code? In the sample you are using noAnimation.

[mvarnagiris]

Yeah I specifically set it to noAnimation. The bug is reproducible with this. Seems like as long as StackAnimator is set, the bug can be reproduced - the animation itself does not matter.

[mvarnagiris]

To reproduce the bug you might need to tap restart about like 5-10 times. If it does not happen then maybe tweak the first value by increasing it a bit

[arkivanov]

Thanks! Is it also reproducible if you specify the animation as follows?

selector = { noAnimation() },

Instead of

selector = { _, _, _ -> noAnimation() },

[mvarnagiris]

Oh interesting. If I do

            animation = stackAnimation(
                disableInputDuringAnimation = true,
                animator = noAnimation(),
            ),

Then I cannot reproduce

[arkivanov]

Thanks for confirming! There are three overloads of the stackAnimation animation function. The one with selector = { child, otherChild, direction -> ... } is annotated with @FaultyDecomposeApi for a reason. Please see the docs for that overload.

I think it's yet another bug in Compose movableContent function. There were few other bugs with movableContent in the past, but they all were fixed. Could you please also try updating or downgrading the version of Compose and see if it changes anything? If it's not yet fixed in a newer Compose version, then we should create a reproducer with movableContentOf but without Decompose (should be pretty easy to do), and report it here. I might help with the reproducer, let me know.

[mvarnagiris]

Ah ok cool I might be able to update our code to not use that MovableStackAnimation. Although we do rely on Direction. I will try to create a reproduced without decompose. Will ping you if I need help with that. Thanks a lot!

[arkivanov]

Thank you!

I have extracted a reproducer without Decompose and filed b/327814644. Closing this issue for now. Thanks again!
