hit 0.2.0

Decouple Flutter layout size from hit-test size, and deliver taps outside parent bounds.

0.2.0

• Fix Hit.defer(paintOnTop: true) with scroll views: deferred paint uses a composited leader/follower so it tracks transforms without a full HitScope repaint.
• Fix disposed-layer crash when reusing paintOnTop follower layers across frames (LayerHandle).
• Expand example app with more demos (Hit.before, resize, window edge, chip, list, slider) and Cupertino UI.

0.1.0

• Initial release: HitLayer, HitScope, Hit.defer / Hit.before, and HitLink.
