Does anyone have an idea why detectTapGestures might not detect taps when there’s an ongoing animation on the screen? I have a separate pointerInput modifier that just logs input events, and both the down&up events are being logged. Once the animation completes, taps are detected fine again. I also added a log to check that my composable wasn’t being re-composed on every frame of the animation, but it doesn’t seem to be 🤔

That's likely because animation was not `launch`ed from the coroutine scope, and instead suspended the CoroutineScope that detectTapGestures is in. Could you share a code snippet?

It’s a little chonky: https://gist.github.com/grandstaish/477a6f7103c949cac9204151383a2b19#file-bottomsheetdialog-kt-L177

(This very similar to ModalBottomSheet from Material, except that it lives inside a fullscreen Android Dialog window.)

That's odd, SwipeableState doesn't use suspend animation at the moment. Which alpha release/snapshot is this built against?

[grandstaish]

I copy/pasted SwipeableState into my app from main (we don’t have a dep on Material)

(Otherwise we’re just using alpha10)

I suspect it's because swipeable consumes the tap gesture as a drag during animation: https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]ommonMain/kotlin/androidx/compose/material/Swipeable.kt;l=557

[grandstaish]

ah yea, i see

[grandstaish]

hmm

[grandstaish]

i guess i’d need to intercept the tap?

[Doris Liu]

The startDraggingImmediately flag in swipeable is to ensure any swiping during the animation gets handled immediately, rather than waiting for a touch slop. I'm not sure what the recommendation would be if you don't want that behavior. @matvei might be able to advise. You might be able to get the tap intercepted if you put the .pointerInput modifier before the swipeable, but you'll need to account for the swipe offset yourself.

Changing the flag to false does work around the problem i am facing. IDK how you figured that out by looking at my code dump mind blown
