Overview
The draggable_scrollbar package enhances vertical list navigation in Flutter by providing a draggable scrollbar with an optional label that displays information about the currently visible item. Users can quickly scroll through long lists by dragging the scrollbar thumb, improving usability and accessibility. The label dynamically updates to reflect the current position, offering visual feedback. Designed for smooth integration with ListView and other scrollable widgets, it supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux.
