promote property

DragPromote? promote

Per-gesture override for displayed-state drag→scale promotion when a 2nd pointer is added. Cascades up to DisplayConfig.dragPromote → Stage.dragPromote → DragPromote.scale when null.

Context-specific: only read when this DragGesture is registered on Stage.drag or DisplayConfig.drag (used in displayed state). No-op when registered on Origin.drag — see hybridFromStage for the hybrid-context analog.

Implementation

final DragPromote? promote;
