Changelog

3.1.0 - 2026-06-30

Added

• Divider line style — new dividerLineStyle parameter with a DividerLineStyle type to draw the divider as a solid, dashed or dotted line, or any fully custom dash pattern.

Changed

• CI: provision OIDC for pub.dev publishing (adds dart-lang/setup-dart and a dart pub publish --dry-run warnings check to the publish workflow). No library code changes.

3.0.0 - 2026-06-17

Added

• Zoom & pan — zoomable/pannable pinch, drag and double-tap zoom applied to both images at once (closes #17).
• Rotation with lock — new ImageCompareSliderController rotates either image in either direction, with lockRotation to rotate both together; also drives zoom, pan, position and reset() (closes #22).
• Custom handle — handleBuilder replaces the painted handle with any draggable widget (closes #2).
• Match image sizes — fit + aspectRatio force differently-sized images into the same box (closes #15).
• onlyHandleDraggable, minScale, maxScale, doubleTapToZoom, doubleTapScale, enableGestureRotation.
