flex_org_chart 0.4.1

Animated, customizable org chart for Flutter: compact flextree layout, pan/zoom, drag-and-drop re-parenting, node editing, department boxes, connections. Ported from d3-org-chart.

0.4.1

• Fixed package archive bloat: 0.4.0's archive accidentally included build caches and stale generated dartdoc (~30 MB) — a root .pubignore replaces .gitignore for packaging, and ours listed only the internal docs directory. The .pubignore now mirrors the repo's ignores; the archive is back to sources, README, and the example. Prefer 0.4.1 over 0.4.0 (identical code).
• README install snippet updated to the current version (it still said ^0.1.0).

0.4.0

• Department bounding boxes: declare groups: [ChartGroup(rootId: ..., label: ..., style: ...)] on the controller and a labeled, styled box is painted behind that node and its visible descendants — beneath links and nodes, animating with layout changes (including shrinking as a collapsing department's members retreat). Styled via GroupBoxStyle (fill, border, corner radius, padding, label style, optional dash) with per-group overrides; nested groups paint outer-first. No d3-org-chart equivalent.
• Internal: the dash-walk (with its invalid-pattern solid-line guard) is now shared between ConnectionPainter and the new GroupBoxPainter as dashedPath.

0.3.0

• Node editing API: addNode, removeNode (children promote to the removed node's parent), reparent (cycle-safe), and updateNode on OrgChartController, plus a data getter. Ops validate up front and throw (ArgumentError/StateError) before mutating anything; every successful edit animates like a drag-drop confirmation.
• New controller callbacks: withParent teaches the controller to write a parent id into your items (required by reparent and child promotion); onDataChanged fires after every successful edit with the new list — the persistence hook. setData never fires it.
• The example app's drag-and-drop now delegates to controller.reparent(...) — one line instead of hand-rolled list surgery.

0.2.0

• Drag-and-drop re-parenting (opt-in): long-press a node to lift it, drop it on its new parent. OrgChart.onReparent receives (node, newParent); the app applies the change and calls setData. OrgChart.canReparent vetoes targets beyond the built-in self/descendant cycle rule; OrgChart.dropTargetBuilder customizes the valid-target overlay.
• Behavior change: OrgChartController.setData now preserves expansion and highlight state for node ids that survive into the new data (preserveState: true by default). Pass preserveState: false for the previous reset-everything behavior.

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.
