1.1.4

  • feat: add interface to GraphAlgorithm: afterDrag, beforeMerge and etc.

  • feat: add LegendDecorator to support the legend of the graph, to control the vertex and edge display. And fix the scroll issue of the legend panel.

    • feat: 新增 LegendDecorator，支持图的图例，控制节点和边的显示。并修复图例面板的滚动问题。 example:
    // First add LegendDecorator to your decorators, 
// then set the legend options.
options
    ..useLegend = false

  • behavior changed: remove speed property from VertexComponent.

    What will be effective is that all the vertex.position will be set to the vertex.cpn.position directly, when decorating the vertex in GraphAlgorithm and sub-classes.

  • behavior changed: set the radius of vertex to a private variable

  • feat: adding GraphRouteDecorator, make the data like a brower history.

    • feat: 新增 GraphRouteDecorator，使数据像浏览器历史一样，支持前进后退，当有合并行为发生时。

  • feat: adding PauseDecorator, make the graph stop updating.

    • feat: 新增 PauseDecorator，使图的节点停止位置更新。

  • feat: adding control panels of decorators. example:

      /// 指定装饰器参数的控制面板创建方法
  CoulombReverseDecorator(
    handleOverlay: kCoulombReserseOverlayBuilder(),
  ),

  • feat: enable configuring the force factor between brother vertexs. example:

    /// @en: Make the repulsion between similar points smaller
/// 
/// @zh: 使相似点之间的排斥力变小
CoulombReverseDecorator(sameSrcAndDstFactor: 1.1),

  • fix: the line added later covers the previous point.

  • feat: support image vertex.

  • feat: using tag similarity as a layout element. example:

    /// @en: Make the repulsion between similar tags smaller
/// 
/// @zh: 使相似标签之间的排斥力变小
CoulombReverseDecorator(sameTagsFactor: 0.8),

  • feat: add dragged property to VertexComponent to indicate whether the vertex is being dragged.

1.1.3+1

  • fix: the crash issue when force is not a number [ForceMotionDecorator].

1.1.3

  • feat: EdgeLineShape can append decorators.

    • feat: 使 EdgeLineShape 可以追加装饰器。

        ..edgeShape = EdgeLineShape(
            decorators: [
                DefaultEdgeDecorator(),
            ],
        )

  • fix: the edge overlap problem of multiple edge graphs with two identical nodes.

  • fix: Edge with the same parameters except for different edge type is misdiagnosed as the same edge.

  • fix: correct the position of the two points of the edge.

    • fix: 修正边的两个点的位置。

  • fix: the overlap issue of the data panel.

1.1.2

  • feat: support specifying legends and legend text build.

    example:

    Options()
    ..legendBuilder = (color, i) { // default
        return RectangleComponent.fromRect(
            Rect.fromLTWH(40, 50.0 + 30 * i, 30, 18),
            paint: Paint()..color = color,
        );
    }
    ..legendTextBuilder = (tag, i, color, position) { // default
        return TextComponent(
            text: tag,
            position: Vector2(position.x + 40, position.y - 6),
            // position: Vector2(position.x + 40, position.y - 2),
            // textRenderer: TextPaint(
            //   style: TextStyle(
            //     fontSize: 17.0,
            //     color: Colors.white,
            //   ),
            // ),
        );
    }
