LzListView class

It allows you to quickly create scrollable lists of child widgets and provides options for customizing the scrolling behavior and appearance.

Example usage:

LzListView(
  controller: myScrollController, // Optional custom ScrollController.
  scrollLimit: [100.0, 500.0], // Optional scroll limits to restrict scrolling within a range.
  children: [Widget1(), Widget2(), ...], // List of child widgets.
  padding: EdgeInsets.all(16.0), // Optional padding around the list.
  shrinkWrap: false, // Whether the list should shrink-wrap its children.
  physics: BounceScroll(), // Custom scroll physics, defaults to BounceScroll.
  onScroll: (controller) {
    // Callback when the list is scrolled.
  },
  autoCache: true, // Whether to automatically cache the list height.
)
