Overview
The appbar_elevation package provides a Flutter widget that creates an AppBar initially flush with the screen body and automatically elevates (rises) when the user scrolls down. This behavior enhances visual hierarchy by revealing the AppBar only during scrolling, offering a clean initial view. It's ideal for apps with long content lists where a dynamic AppBar improves UX. The widget is lightweight and integrates seamlessly into existing scrollable layouts like ListView or CustomScrollView. It supports smooth transitions and works without requiring complex custom logic. The source code is publicly available on GitHub for transparency and contribution.
