swipeToRemoveExtent property

The minimal extent, as a ratio of item movement, to trigger swipe-to-remove.

This property represents the minimum ratio of the item's movement along the swipe direction required to initiate the swipe-to-remove action. When a user swipes an item to an extent greater than or equal to this ratio, the swipe-to-remove action will be initiated for the corresponding item within the AnimatedReorderable widget.
