Overview
The scroll_pos package enhances Flutter's ScrollController by adding utility functions to determine the position of list items relative to the screen. It simplifies tasks like detecting when an item is fully visible, partially in view, or near the top/bottom of the viewport. Ideal for building interactive lists, infinite scrolling, or dynamic UIs that respond to scroll state. The package supports all major platforms and integrates seamlessly with existing ScrollController implementations.
