flex_org_chart 0.1.0

Highly customizable, animated org chart widget for Flutter: pan/zoom, compact flextree layout, highlighting, and connections. Ported from d3-org-chart.

0.1.0

Initial release. A highly customizable, animated org chart widget for Flutter, ported from d3-org-chart with a d3-flextree-based compact layout.

• Data & layout: stratify builds a tree from any flat list via idOf/parentIdOf callbacks, detecting empty data, duplicate ids, missing parents, and cycles (OrgChartDataException). LayoutEngine computes node and link positions for all four ChartLayout directions (top, bottom, left, right), with an optional flextree "compact" pass that folds leaf-heavy subtrees into two columns.
• Controller: OrgChartController owns data and expansion/highlight state — setData, expand/collapse/setExpanded, expandAll/ collapseAll, highlight/highlightPathToRoot/clearHighlights, nodeById/visibleNodes/connections/dataError — and drives viewport navigation (fit, centerNode, zoomIn/zoomOut) through whichever OrgChart widget is currently attached.
• Widget: OrgChart renders the controller's current layout with a fully custom nodeBuilder, pinch/drag pan and scroll-wheel zoom, animated enter/exit transitions when the visible node set or layout changes, a customizable expand/collapse affordance (DefaultExpandButton or expandButtonBuilder), node tap callbacks, and configurable error/empty states.
• Connections: independent, non-hierarchical Connection links are rendered as dashed, labeled, arrow-headed arcs (ConnectionStyle) alongside the hierarchical parent/child links (LinkStyle).
• Highlighting: highlight/highlightPathToRoot mark nodes and their link/ancestor chain, styled via highlightedLinkStyle and the isHighlighted/isOnHighlightedPath flags exposed on OrgNode.
• Not yet available: node editing, image/PDF export, pagination for very large trees, and drag-and-drop re-parenting. See the README roadmap.
