Classes

ChildDetails<ParentDataType extends ParentData>

DraggableNode<NodeType, IdType extends Object>

Edge<EdgeType, IdType extends Object>

EdgeDetails<EdgeType, NodeType, IdType extends Object>

Graph<EdgeType, NodeType, IdType extends Object>

This a class to hold logic related to an abstract graph and its operations and should NOT be in any way related to UI or rendering.

LayeredGraph<EdgeType, NodeType, IdType extends Object>

LayeredTreeDelegate<EdgeType, NodeType, IdType extends Object>

MultiChildEdge<EdgeType, NodeType, IdType extends Object>

Node<NodeType, IdType extends Object>

A Node is a node in the SkillTree. Parent and child information is not stored here but in the edges. This is done to keep cyclic graphs possible.

NodeDetails<NodeType, IdType extends Object>

PositionedGraph<EdgeType, NodeType, IdType extends Object>

RenderMultiChildEdge<EdgeType, NodeType, IdType extends Object>

The fields of this RenderObject are initialized in the layout phase. This is because we must first know the size of the node widgets.

RenderSkillTree<EdgeType, NodeType, IdType extends Object>

This class provides useful abstractions across both the graph theory model and the render model.

SkillEdge<EdgeType, NodeType, IdType extends Object>

An edge that will be rendered as a line between two widget vertices.

SkillEdgeParentData<EdgeType, IdType extends Object>

SkillNode<NodeType, IdType extends Object>

A representation of a node in the skill tree.

SkillNodeLayout<NodeType, IdType extends Object>

SkillNodeParentData<NodeType, IdType extends Object>

SkillParentData

A super parent data class that is temporarily initialized in RenderSkillTree to later then be converted to SkillNodeParentData or SkillEdgeParentData respective of the type of the child.

SkillTree<EdgeType, NodeType, IdType extends Object>

A widget to create a skill tree. This assumes a digraph structure. That is, edges are directed.

SkillTreeDelegate<EdgeType, NodeType, IdType extends Object, GraphType extends Graph<EdgeType, NodeType, IdType>>

A delegate decides the layout to be used for the skill tree

Extensions

CastEdge on Edge<EdgeType, IdType>

NodeCopyWith on Node<NodeType, IdType>

Functions

defaultCubicEdgePathBuilder({required Offset toNodeCenter, required Offset fromNodeCenter, required List<Rect> allNodeRects, required List<Offset> controlPointCenters}) → Path

defaultCubicEdgePathPainter({required Path path, required Canvas canvas}) → void

defaultEdgePathBuilder({required Offset toNodeCenter, required Offset fromNodeCenter, required List<Rect> allNodeRects, required List<Offset> controlPointCenters}) → Path
