I am experimenting with gesture detection in compose. Here is the code snipped:

Surface(color = MaterialTheme.colors.background) {
                    Box(modifier = Modifier.size(100.dp).background(Color.Yellow)
                        .pointerInput(Unit) {
                            detectVerticalDragGestures(
                                onDragCancel = { Log.d("AAAA", "onDragCancel") },
                                onDragEnd = { Log.d("AAAA", "onDragEnd") },
                                onVerticalDrag = { change, dragAmount -> Log.d("AAAA", "Drag change: $dragAmount") }
                            )
                        })
                }

It is a simple Box. The issue: onDragEnd and onDragCancel are never called. The onVerticalDrag works like a charm. Is there any mistake in my code or should I file a bug? Compose version : alpha12

you have to consume the change in onVerticalDrag if you want to accept the drag motion
