Overview
ScrollDragDetector is a Flutter package that enables precise drag gesture detection within scrollable widgets. It resolves common issues where nested scroll views interfere with drag interactions by intelligently distinguishing between scroll and drag gestures. Designed for use in complex UIs with layered scrollable content, it ensures smooth and responsive drag behavior even when embedded inside scrollable containers. The package supports all major platforms and integrates seamlessly with existing Flutter projects.
Use cases

Suitable for
- Developers building interactive scrollable UIs
- Apps requiring precise drag gestures
- Complex gesture-based interfaces
- Flutter projects with nested scroll views
- Cross-platform mobile and web apps
Considerations
