graphview 1.5.0

GraphView is used to display data in graph structures. It can display Tree layout, Directed and Layered graph. Useful for Family Tree, Hierarchy View.

1.5.0

• MAJOR UPDATE: Added 5 new layout algorithms
  • BalloonLayoutAlgorithm: Radial tree layout with circular child arrangements around parents
  • CircleLayoutAlgorithm: Arranges nodes in circular formations with edge crossing reduction
  • RadialTreeLayoutAlgorithm: Converts tree structures to polar coordinate system
  • TidierTreeLayoutAlgorithm: Improved tree layout with better spacing and positioning
  • MindmapAlgorithm: Specialized layout for mindmap-style distributions
• NEW: Node expand/collapse functionality with GraphViewController
  • collapseNode(), expandNode(), toggleNodeExpanded() methods
  • Hierarchical visibility control with animated transitions
  • Initial collapsed state support via setInitiallyCollapsedNodes()
• NEW: Advanced animation system
  • Smooth expand/collapse animations with customizable duration
  • Node scaling and opacity transitions during state changes
  • toggleAnimationDuration parameter for fine-tuning animations
• NEW: Enhanced GraphView.builder constructor
  • animated: Enable/disable smooth animations (default: true)
  • autoZoomToFit: Automatically zoom to fit all nodes on initialization
  • initialNode: Jump to specific node on startup
  • panAnimationDuration: Customizable camera movement timing
  • centerGraph: Center the graph within viewport
  • controller: GraphViewController for programmatic control
• NEW: Navigation and camera control features
  • jumpToNode() and animateToNode() for programmatic navigation
  • zoomToFit() for automatic viewport adjustment
  • resetView() for returning to origin
  • forceRecalculation() for layout updates
• IMPROVED TreeEdgeRenderer with curved/straight connection options
• IMPROVED: Better performance with caching for graphs
• IMPROVED: Sugiyama Algorithm with postStraighten and additional strategies

1.2.0

1.0.0-nullsafety.0

• Null Safety Support

0.7.0

• Added methods for builder pattern and deprecated directly setting Widget Data in nodes.

0.6.7

• Fix rect value not being set in FruchtermanReingoldAlgorithm (#27)

0.6.6

• Fix Index out of range for Sugiyama Algorithm (#20)

0.6.5

0.6.1

• Fix coloring not happening for the whole graphview
