Release notes
- Added TreemapChart.surrounding, TreemapSurroundingContent, and TreemapSurroundingGrid for placing breadcrumbs, legends, and custom content in eight direction-aware cells around the treemap. The grid supports named slots or fromMap, uses standard flex layout, and leaves sizing to callers.
- Breadcrumbs and legends work as either direct surrounding layers or grid content; custom content uses the widget and builder factories.
- Split presentation from the treemap core. TreemapChart now consumes replaceable tile, label, semantics, tooltip, and surrounding-layer contracts; all contracts and implementations share the any_treemap.dart entry point.
- Removed implicit labels, tooltips, legends, breadcrumbs, semantics, empty text, palette, fallback colors, animation, and clipping from the core chart. A tile layer is explicit, and all color-scale fallbacks are required.
- Added no-op, composite, and widget-builder layers plus immutable visual contexts. Included labels and semantics target deepest visible blocks while tile layers retain ancestor geometry for hierarchy painting.
- Added optimized TreemapCanvasLabels and fully customizable, per-node clipped TreemapWidgetLabels. Canvas labels support a configurable ellipsis; label rendering no longer measures or changes layout geometry.
- Moved interaction contracts out of appearance code and changed presentation data labels/color values to remain nullable instead of inventing display strings or weight-based colors in the core.
- Removed per-node minimum dimensions from TreemapNode; minimum width, height, and area thresholds now belong exclusively to TreemapLayoutConfig.
- Removed device-pixel snapping from core geometry and removed implicit high-contrast appearance mutation and context state.
- Renamed node and record colorValue inputs to color. A Flutter Color now bypasses the included appearance resolver's configured color scale.
- Removed emptyBuilder, TreemapEmptyBuilder, and TreemapEmptyState; empty geometry now always produces the neutral SizedBox.shrink output.
- Moved flat-record construction to TreemapNode.fromRecords and removed both TreemapNodeFactory and TreemapChart.fromRecords.
