ShouldIgnorePointerWhenScrolling
/// Whether the contents of the widget should ignore [PointerEvent] inputs.
///
/// Setting this value to true prevents the use from interacting with the
/// contents of the widget with pointer events. The widget itself is still
/// interactive.
///
/// For example, if the scroll position is being driven by an animation, it
/// might be appropriate to set this value to ignore pointer events to
/// prevent the user from accidentally interacting with the contents of the
/// widget as it animates. The user will still be able to touch the widget,
/// potentially stopping the animation.
///
///
/// if true, child can't accept event before [ExtendedPageView],[ExtendedScrollable] stop scroll.
///
///
/// if false, child can accept event before [ExtendedPageView],[ExtendedScrollable] stop scroll.
/// notice: we don't know there are any issues if we don't ignore [PointerEvent] inputs when it's scrolling.
///
///
/// Two way to solve issue that child can't hittest before [PageView] stop scroll.
/// 1. set [shouldIgnorePointerWhenScrolling] false
/// 2. use LessSpringClampingScrollPhysics to make animation quickly
///
/// default is true.
