wrapForLongPress method Null safety

GestureLongPressCallback? wrapForLongPress(
  1. GestureLongPressCallback? callback,
  2. BuildContext context
)

Wraps a GestureLongPressCallback to provide platform specific feedback for a long press before the provided callback is executed.

On Android the platform-typical vibration is triggered. On iOS this is a no-op as that platform usually doesn't provide feedback for a long press.

    callback();
