Top-level properties summary

Duration	`DoubleTapMinTime` The minimum time from the end of the first tap to the start of the second tap in a double-tap gesture.
Dp	`DoubleTapSlop` Distance between the initial position of the first touch and the start position of a potential second touch for the second touch to be considered the second touch of a double-tap gesture.
Duration	`DoubleTapTimeout` The maximum time from the start of the first tap to the start of the second tap in a double-tap gesture.
Dp	`DoubleTapTouchSlop` The maximum distance that the first touch in a double-tap gesture can travel before deciding that it is not part of a double-tap gesture.
Dp	`HoverTapSlop` Maximum distance between the down and up pointers for a tap.
Duration	`HoverTapTimeout` Maximum length of time between a tap down and a tap up for the gesture to be considered a tap.
Duration	`JumpTapTimeout` The maximum time from the start of the first tap to the start of the second tap in a jump-tap gesture.
Duration	`LongPressTimeout` The time before a long press gesture attempts to win.
Dp	`MaxFlingVelocity` Drag gesture fling velocities are clipped to this value.
Dp	`MinFlingVelocity` The minimum velocity for a touch to consider that touch to trigger a fling gesture.
Dp	`PagingTouchSlop` The distance a touch has to travel for the framework to be confident that the gesture is a paging gesture.
Dp	`PanSlop` The distance a touch has to travel for the framework to be confident that the gesture is a panning gesture.
Duration	`PressTimeout` The time that must elapse before a tap gesture sends onTapDown, if there's any doubt that the gesture is a tap.
Dp	`ScaleSlop` The absolute cumulative average change in distance of all pointers from the average pointer over time that must be surpassed to indicate the user is trying to scale.
Dp	`TouchSlop` The distance a touch has to travel for the framework to be confident that the gesture is a scroll gesture, or, inversely, the maximum distance that a touch can travel before the framework becomes confident that it is not a tap.
Dp	`WindowTouchSlop` The margin around a dialog, popup menu, or other window-like composable inside which we do not consider a tap to dismiss the composable.
Duration	`ZoomControlsTimeout` The time for which zoom controls (e.

Extension functions summary

For kotlin.collections.List
Boolean	`List<PointerInputChange>.anyPointersInBounds(bounds: IntSize)` Utility method that determines if any pointers are currently in bounds.

For Modifier
Modifier	`Modifier.doubleTapGestureFilter(onDoubleTap: (Offset) -> Unit)` Responds to pointers going down and up (tap) and then down and up again (another tap) with minimal gap of time between the first up and the second down.
Modifier	`Modifier.dragGestureFilter(dragObserver: DragObserver, canDrag: (Direction) -> Boolean = null, startDragImmediately: Boolean = false)` This gesture detector detects dragging in any direction.
Modifier	`Modifier.dragSlopExceededGestureFilter(onDragSlopExceeded: () -> Unit, canDrag: (Direction) -> Boolean = null, orientation: Orientation? = null)` This gesture filter detects when the average distance change of all pointers surpasses the touch slop.
Modifier	`Modifier.longPressDragGestureFilter(longPressDragObserver: LongPressDragObserver)` This gesture detector detects dragging in any direction, but only after a long press has first occurred.
Modifier	`Modifier.longPressGestureFilter(onLongPress: (Offset) -> Unit)` Responds to a pointer being "down" for an extended amount of time.
Modifier	`Modifier.pressIndicatorGestureFilter(onStart: (Offset) -> Unit = null, onStop: () -> Unit = null, onCancel: () -> Unit = null, enabled: Boolean = true)` This gesture detector has callbacks for when a press gesture starts and ends for the purposes of displaying visual feedback for those two states.
Modifier	`Modifier.rawDragGestureFilter(dragObserver: DragObserver, canStartDragging: () -> Boolean = null, orientation: Orientation? = null)` This gesture detector detects dragging in any direction.
Modifier	`Modifier.rawPressStartGestureFilter(onPressStart: (Offset) -> Unit, enabled: Boolean = false, executionPass: PointerEventPass = PointerEventPass.Main)` Reacts if the first pointer input change it sees is an unconsumed down change, and if it reacts, consumes all further down changes.
Modifier	`Modifier.rawScaleGestureFilter(scaleObserver: RawScaleObserver, canStartScaling: () -> Boolean = null)` This gesture detector detects scaling.
Modifier	`Modifier.scaleGestureFilter(scaleObserver: ScaleObserver)` This gesture detector detects scaling.
Modifier	`Modifier.scaleSlopExceededGestureFilter(onScaleSlopExceeded: () -> Unit)` This gesture detector detects when a user's pointer input is intended to include scaling.
Modifier	`Modifier.scrollGestureFilter(scrollCallback: ScrollCallback, orientation: Orientation, canDrag: (Direction) -> Boolean = null, startDragImmediately: Boolean = false)` Like Modifier.dragGestureFilter, this gesture filter will detect dragging, but will only do so along the given orientation.
Modifier	`Modifier.tapGestureFilter(onTap: (Offset) -> Unit)` This gesture detector fires a callback when a traditional press is being released.

Top-level properties

DoubleTapMinTime

val DoubleTapMinTime: Duration

The minimum time from the end of the first tap to the start of the second tap in a double-tap gesture. (Currently not honored by the DoubleTapGestureFilter.)

DoubleTapSlop

val DoubleTapSlop: Dp

Distance between the initial position of the first touch and the start position of a potential second touch for the second touch to be considered the second touch of a double-tap gesture.

DoubleTapTimeout

val DoubleTapTimeout: Duration

The maximum time from the start of the first tap to the start of the second tap in a double-tap gesture.

DoubleTapTouchSlop

val DoubleTapTouchSlop: Dp

The maximum distance that the first touch in a double-tap gesture can travel before deciding that it is not part of a double-tap gesture. DoubleTapGestureFilter also restricts the second touch to this distance.

HoverTapSlop

val HoverTapSlop: Dp

Maximum distance between the down and up pointers for a tap. (Currently not honored by the TapGestureFilter.

HoverTapTimeout

val HoverTapTimeout: Duration

Maximum length of time between a tap down and a tap up for the gesture to be considered a tap. (Currently not honored by the TapGestureFilter.)

JumpTapTimeout

val JumpTapTimeout: Duration

The maximum time from the start of the first tap to the start of the second tap in a jump-tap gesture.

LongPressTimeout

val LongPressTimeout: Duration
