wrapForLongPress method Null safety
- GestureLongPressCallback? callback,
- 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.

- forLongPress to just trigger the platform-specific feedback without wrapping a GestureLongPressCallback.
Implementation
static GestureLongPressCallback? wrapForLongPress(GestureLongPressCallback? callback, BuildContext context) {
if (callback == null) {
return null;
}
return () {
Feedback.forLongPress(context);
callback();
};
}
