origin 1.5.2

Interactive hero animations for Flutter.

1.5.2

• Send overlays now clip against the origin container, matching the main overlay's clipping during reorder.
• Container expansion tracks per-frame drag deltas (monotonic — only grows during drag). Animated shrink back to origin container on dismiss, synced with the rect animation.

1.5.1

• Only reject multi-pointer when the recognizer has explicit gestures. Keeps pinch working on Stage's root recognizer.

1.5.0

• Breaking: dismiss signature changed from dismiss([Object? tag]) to dismiss({Object? tag, Object? except}). except skips the given tag from the return-all loop (for preserving swap targets).
• Breaking: unregister now requires the OriginEntry instance. Identity-aware unregister only removes the tag from the registry if the stored entry matches, preventing transient duplicates during keyed-children reorders.
• register no longer asserts on duplicate tags — transient duplicates are tolerated and later resolved via identity-aware unregister.
• _displace now returns other parked/sending items to home on hover change, cleaning up stale displacements proactively.
• StageScaleRecognizer rejects the arena when a second pointer joins a single-pointer-only recognizer — releases pointers so nested Origins with multi-pointer gestures can claim them.

1.4.0

• onEnd accepts FutureOr<void> and is awaited before reset().
• dismiss() returns all active sends to .returning state.

1.3.1

• Guard dismiss(tag) to prevent stale tag states when tag has no active send.

1.3.0

• Swap support: swapTags and onSwap on Origin for drag-to-reorder between Origins.
• _SendLayer animates displaced items to target and back.
• TagState enum (idle, sending, parked, returning) tracks displacement state.
• Stage.stateOf(context, tag) and Stage.isActiveOf(context, tag) accessors.
• displace, release, captureEntry on StageData.
• isTagOf now returns true for displaced tags (not just the active tag). Use isActiveOf for the previous behavior.

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.
