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

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

This takes inspiration from but does not extend or implement MultiChildLayoutDelegate as that class is specific to a CustomMultiChildLayout does is not "delegated" any real work other than holding layout config.

Implementers

• LayeredTreeDelegate

Constructors

SkillTreeDelegate({Listenable? relayout})

Creates a layout delegate.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

layoutEdges(BoxConstraints constraints, SkillNodeLayout<NodeType, IdType> skillNodeLayout, GraphType graph, List<EdgeDetails<EdgeType, NodeType, IdType>> edgeChildrenDetails, List<NodeDetails<NodeType, IdType>> nodeChildrenDetails) → void

We need to layout edges. However, an edge is not a direct RenderObject. Instead, it is a MultiChildRenderObject. Therefore, we must position the edges first based off the nodes.

layoutNodes(BoxConstraints constraints, GraphType graph, List<NodeDetails<NodeType, IdType>> nodeChildrenDetails) → SkillNodeLayout<NodeType, IdType>

Returns information about the size and position of the nodes

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

shouldRelayout(covariant SkillTreeDelegate<EdgeType, NodeType, IdType, GraphType> oldDelegate) → bool

Override this method to return true when the children need to be laid out.

toString() → String

Override this method to include additional information in the debugging data printed by debugDumpRenderTree and friends.

override

Operators

operator ==(Object other) → bool

The equality operator.
