origin 1.2.1

Interactive hero animations for Flutter.

1.2.1

• Fix sendEntry using stale origin rect instead of measured position.

1.2.0

• Container computed in Stage via ValueNotifier<OriginRect?>, expand-only during interaction, shrinks on dismiss.
• Stage.isDismissingOf(context) aspect-based accessor.
• dismissing field on StageData.
• Dismiss drag anchors rect to pointer — content stays pinned under finger while scaling.

1.1.0

• Breaking: itemGesturing / setItemGesturing replaced by locked / setLocked. Stage defaults to locked, unlocks after animateToBase completes, relocks on reset.
• Breaking: origin, originContainer, display, displayContainer, aspectRatio on StageData changed from ValueNotifier to plain values with setters.
• Breaking: originContainer and displayContainer are now nullable. null means full screen (no container clip).
• Container clipping: overlay clips content to an animated container rect using ClipPath. Container expands from originContainer toward displayContainer as the item moves.
• Stage.isLockedOf(context) static accessor.
• containerTag no longer falls back to widget.tag — only explicit container tags are measured.

1.0.0

• Breaking: OriginDisplay + OriginScope merged into Stage.
• Breaking: OriginItem replaced by Origin.
• Breaking: triggerEntry split into openEntry and sendEntry.
• Breaking: effectTransform replaced by Rotation class with toMatrix4.
• InheritedModel aspects: widgetOf, hasWidgetOf, tagOf, isTagOf.
• originToBaseProgress notifier for border radius and scrim interpolation.
• Configurable backgroundColor scrim on Stage.
• onEnd overridable via setOnEnd or sendEntry optional parameter.
• perspective on Rotation class and runEffect.

0.3.0

• Breaking: OriginItem.builder signature changed from WidgetBuilder? to Widget Function(BuildContext, Widget)? — receives the child widget as second parameter.
• Breaking: OriginItem.builder now acts as the gesture builder in the overlay. If no OriginGesture.builder is provided, the item's builder is used instead.
• OriginItem.builder no longer replaces the overlay widget — widget.child is always used. The builder wraps the clipped child in the overlay.
• Overlay blocks gestures on content beneath when active (absorbs pointers between content and overlay layer).

0.2.0

• Breaking: OriginScope.registerItem callback changed from VoidCallback to Future<void> Function([Rect Function(Rect)?]).
• Breaking: OriginScope.triggerItem accepts optional send callback for programmatic dismiss to a computed rect.
• Breaking: Scope maps moved from widget instance to display state, fixing registration loss on rebuild.
• OriginItem.onTap replaces tap, provides OriginTapEvent with animateToBase and runEffect.
• OriginItem.onEnd callback fires after dismiss animation, before reset.
• OriginItem.perspective field with fallback chain: runEffect param → item → 0.
• OriginRect.copyWith method.
• Gesture builder on OriginGesture applied in overlay outside ClipRRect.
• runEffect with individual params, back-and-forth animation.
• Effect transform uses Matrix4? with null check.
• Removed OriginEffect class.

0.1.0

• Custom gesture recognizer for arena control.
• GlobalKey state preservation across overlay.
• Vertical shrink dismiss, multi-finger zoom.
• Early gesture acceptance, reduced slop.

0.0.3

• Add stackBuilder for showing builder on top of child.

0.0.2

• Add tag, visibility, dismiss, animateToBase.
• InheritedModel with aspect-based rebuilds.
• ClipRRect and borderRadius animation on items.
• Safe controller resets.

0.0.1

• Initial release.
