sankey_diagram_flutter 1.1.0

A highly customizable Sankey diagram widget for Flutter. Visualize broker distribution, fund flows, and any flow-based data with smooth bezier curves and full interactivity.

1.1.0

• Add autoLayout mode: column positions derived automatically from link topology using BFS (longest-path depth), matching d3-sankey behaviour.
• Add iterative relaxation (layoutIterations, default 6) that minimises link crossings and aligns nodes with their neighbours.
• Add NodeAlignment enum (left, right, center, justify) to control sink/source placement during auto-layout.
• Add circular link support: backward flows (source column ≥ target column) are detected (LayoutLink.isCircular) and rendered as upward arcs.
• Fix numColumns to use max + 1 instead of distinctCount so non- contiguous explicit columns are positioned correctly.

1.0.1

• Add dartdoc comments to all public API classes, enums, and methods.
• Limit pubspec screenshots to 10 (pub.dev maximum).

1.0.0

• Initial version.
