flutter_graph_view 1.1.4

Widgets for beautiful graphic data structures, such as force-oriented diagrams.

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。

      Options()
          ..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,
              //   ),
              // ),
          );
      }
