scaleVelocityCancel property
Per-gesture strength of scale-velocity-based translation cancellation
in [0, 1]. Cascade fallback when null: DisplayConfig.scaleVelocityCancel
→ Origin.scaleVelocityCancel → Stage.scaleVelocityCancel → 0.5.
Most relevant on ScaleGesture; a no-op on DragGesture since
scaleVelocity is ~0 there.
Implementation
final double? scaleVelocityCancel;
