Overview
The linked_scroll_controller package provides a scroll controller that synchronizes the scrolling behavior of two or more scroll views. When one scroll view is scrolled, the others automatically follow, maintaining consistent positions across all linked views. This is particularly useful for creating coordinated UIs such as side-by-side lists, dual-pane layouts, or synchronized content panes. The package supports all major platforms including Android, iOS, Web, macOS, Windows, and Linux, ensuring cross-platform consistency. It integrates seamlessly with Flutter’s existing scroll system and requires minimal setup.
