Description

Adds a "Views reordered during a gesture" use case to the Gesture Detectors page and a matching subsection to the upgrade guide, documenting that reordering a GestureDetector's view cancels the active gesture and that VirtualGestureDetector keeps it alive on Android.

📝 Summary

Summary by CodeRabbit

• Documentation
  • Added guidance for preserving active gestures when Android list items are reordered, including the required nesting of VirtualGestureDetector within InterceptingGestureDetector.
  • Added a reorderable FlatList example.
  • Clarified that reattaching a view cancels active gestures on iOS and web, and that GestureDetector placement can affect SVG-based components.

The core component documentation and upgrade guide describe how view reordering can affect active gestures. They explain Android detector usage for reorderable lists and note that reattachment cancels active gestures on iOS and web.

Changes: Virtual detector documentation

Layer / File(s)	Summary
Document detector behavior packages/docs-gesture-handler/docs/core-components/gesture-detector.mdx, packages/docs-gesture-handler/docs/guides/upgrading-to-3.mdx	The docs describe how GestureDetector detachment and reattachment can affect view hierarchy-dependent components such as SVG and cancel active gestures. They introduce InterceptingGestureDetector and VirtualGestureDetector.
Document reorderable list usage packages/docs-gesture-handler/docs/core-components/gesture-detector.mdx, packages/docs-gesture-handler/docs/guides/upgrading-to-3.mdx	The docs show FlatList examples that wrap the list in InterceptingGestureDetector and each row in VirtualGestureDetector. They state that this preserves active gestures during reordering on Android, while reattachment cancels gestures on iOS and web.
