It utilizes `GesturePointersUtility` for gesture tracking and `HitTestResult` and `MotionEvent` to process touch events. Key actions include creating gestures via `tryCreateGestures`, adding or removing listeners for gesture start events using `addOnGestureStartedListener` and `removeOnGestureStartedListener` and processing touch input via `onTouch`. It also manages a list of gestures, and interfaces with the `OnGestureStartedListener` to trigger callbacks when a pinch starts.\n"]]
