A Flutter widget that enhances a ListView by revealing a hidden top element when the user scrolls down, then hiding it again when scrolling up. It provides a smooth, interactive experience for displaying supplementary content—like filters or actions—without cluttering the main list. The behavior is triggered by scroll direction and sensitivity, making it ideal for dynamic UIs. It's lightweight and easy to integrate into existing list-based interfaces.
