v1.2.0

1.2.0

• feat: add stopDrag to FlutterGraphWidget to control the drag behavior of the graph view.

  支持通过 FlutterGraphWidget.stopDrag = false; 停止视窗拖拽。

• fix[#27]: the issue does not work properly in version 1.29.0.

  在 1.29.0 版本中无法正常工作的问题

Behavior change:

• Upgrade flame to 1.29.0, so the gameRef in VertexComponent should be replaced with game, when using vertex.cpn?.gameRef.

  升级 flame 到 1.29.0 版本，所以 VertexComponent 中的 gameRef 应该替换为 game，用到 vertex.cpn?.gameRef时。

1.1.6

• feat: 为 edge 新增 SolidArrowEdgeDecorator 实心箭头装饰器

  support SolidArrowEdgeDecorator for edge

1.1.5

• feat: Support controlling the game pause or play through the options.pause.

  支持通过 options.pause 控制游戏暂停或播放。

• feat: Support specifying node components through options.vertexComponentNew

  支持通过 options.vertexComponentNew 指定节点组件。

1.1.4+1

• fix: the issue of edge overlap when the edgeName is different but same src, dst and edgeId.

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: 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.

v1.1.2

• 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,
              //   ),
              // ),
          );
      }
