How do I prevent when I touch screen, scrolling stops in Flutter

Question

I use globalkey and Scrollable.ensurevisible for each titles. It works well, but when l touch screen after click title, scrolling stops. Do u have any idea?

///  Scroll to the selected category
await Scrollable.ensureVisible(
  widget.categoriesList[index].key.currentContext!,
  duration: const Duration(milliseconds: 500),
  alignment: 0.05,
  curve: Curves.fastOutSlowIn,
);
