Reactify

🫧 Metaball-style "gooey" UI for Compose Multiplatform: blobs that merge, stretch a neck, and pinch apart as items animate from a source into a target.

What is this?

Reactify renders a frame as a GooeyScene: a list of blobs (round rects, circles, capsules) that smoothly merge via a polynomial smooth-min, plus cutouts that smoothly subtract. On top of that SDF core it builds three ready-to-use pieces:

• Transfer — drag or tap an item in a list and watch a token fly into a card, with a gooey bridge connecting the two while it travels.
• Notch shape — a rounded rect with a concave notch that opens/closes in sync with a transfer target, built from the same distance field.
• Sliding indicators — a liquid pill that bridges between a bottom-nav item or a segmented control option as the selection changes.

Rendering is pluggable: AGSL (RuntimeShader) on Android API 33+, SkSL via Skiko on iOS, or a CPU path-tracing fallback everywhere else — pick automatically with GooeyRenderers.auto().
