morphos_ui 0.1.1

Animate thousands of Flutter UI items on one spring-driven surface: a single render object with spring physics, viewport culling and 100k-node scaling.

0.1.1

• Homepage and README now link to the package's documentation page on flutterdev.in. No code changes.

0.1.0

First release.

• MorphOSField widget and MorphOSRenderBridge render object: a whole field of nodes in one leaf RenderBox.
• Stride-12 packed layout buffer plus a stride-24 auxiliary buffer; buffers grow only on spec changes.
• One field matrix per layout (contain, cover, fill, fitWidth, none).
• Fixed-step (1/240 s) semi-implicit spring solver: position, size and presence; nodes matched by id across spec changes; animated entry and exit; stagger by index or from a point; reduced-motion snapping.
• Two paint modes: shapes (default; one drawRRect per node, text layered exactly) and vertices: rounded, bordered, rotated, anti-aliased nodes drawn with Canvas.drawVertices. Geometry is sized to each shape: 9 vertices for a square card, and just enough arc segments for rounded corners to stay within a quarter pixel. One call per 65,535 vertices, split only when text must sit under a later node at rest.
• Image atlas with per-vertex UVs so textured and flat nodes share a draw. Images keep their proportions (imageFit: MorphImageFit.cover, the default) or stretch (MorphImageFit.fill).
• Cached paragraphs for node text with max lines, ellipsis and clipping.
• Hit testing through the inverse matrix (rotation, rounded corners), with a uniform grid above 2,000 nodes.
• Taps, drags with fling momentum, mouse hover and cursor, wheel and drag scrolling, keyboard focus (Tab, arrows, Enter/Space), semantics.
• MorphController (a plain ChangeNotifier): scrollToNode, animateTo, jumpTo, nodeRect, nodeAt, whenSettled; plus an onSettled callback.
• Vertical or horizontal scrolling (scrollDirection, MorphFit.fitHeight), with screen-reader scroll actions.
• Right-to-left mirroring of node positions and rotations (mirrorInRtl).
• Node, vertex and index buffers shrink after a large field becomes small.
• Scaling: viewport culling in both paint modes, an active set in the solver (only moving nodes are integrated), MorphFieldSpec.withNode / withNodes for cheap single-node edits, and semantics limited to nodes near the viewport. Measured up to 100,000 nodes.
• benchmark/ app (not published): five-way comparison with a hand-written CustomPainter, Flame and a widget tree, a 20k–100k scaling run, plus timeline-trace and spec-cost runs.
• Optional sheen fragment-shader overlay, performance overlay, node-bounds debug overlay, and a recorder for bit-exact replay.
