Properties

bounds → GestureBounds

Directional bounds active during this gesture (drag) or directional overflow during scale (rect edges past container edges).

final, inherited

builder → StageBuilder?

final, inherited

constraints → GestureConstraints?

final, inherited

expand → ExpandBounds?

Expand-axis bound config (with optional maxScale threshold).

final

hashCode → int

The hash code for this object.

no setter, inherited

hybridFromStage → ScaleHybrid?

Per-gesture override for how Stage receives new pointers while this scale is active. Cascades up to Origin.scaleHybridFromStage → Stage.scaleHybridFromStage → ScaleHybrid.lock when null.

final

onRelease → OnRelease?

Called when the gesture ends with a ReleaseContext — raw end-state inputs. Consumer calls Stage.of(context).release(Release.toDisplay(data)) for the default plan, or builds a custom plan and calls .run(...) / .backToOrigin(data) / etc.

final, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

scaleVelocityCancel → double?

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.

final, inherited

shrink → ShrinkBounds?

Shrink-axis bound config (with optional minScale threshold).

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
