detectTapGesturesIf

If predicate returns true: detects tap, double-tap, and long press gestures and calls onTap, onDoubleTap, and onLongPress, respectively, when detected. onPress is called when the press is detected and the PressGestureScope.tryAwaitRelease and PressGestureScope.awaitRelease can be used to detect when pointers have released or the gesture was canceled. The first pointer down and final pointer up are consumed, and in the case of long press, all changes after the long press is detected are consumed.

Each function parameter receives an Offset representing the position relative to the containing element. The Offset can be outside the actual bounds of the element itself meaning the numbers can be negative or larger than the element bounds if the touch target is smaller than the ViewConfiguration.minimumTouchTargetSize.

When onDoubleTap is provided, the tap gesture is detected only after the ViewConfiguration.doubleTapMinTimeMillis has passed and onDoubleTap is called if the second tap is started before ViewConfiguration.doubleTapTimeoutMillis. If onDoubleTap is not provided, then onTap is called when the pointer up has been received.

After the initial onPress, if the pointer moves out of the input area, the position change is consumed, or another gesture consumes the down or up events, the gestures are considered canceled. That means onDoubleTap, onLongPress, and onTap will not be called after a gesture has been canceled.

If the first down event is consumed somewhere else, the entire gesture will be skipped, including onPress.
