NodeSpec class

A node in the document's scene graph.

Identity is the stable id; name is a non-identifying label kept for animation binding and name lookup. Hierarchy is by children id list. A node is either a plain node or, when instance is non-null, a prefab instance.

Constructors

NodeSpec({required LocalId id, String name = '', TransformSpec? transform, List<LocalId>? children, List<ComponentSpec>? components, int layers = 1, LocalId? skin, PrefabInstanceSpec? instance, bool excludeFromWindingParity = false, bool visible = true})

Creates a node with the given stable id.

Properties

children → List<LocalId>

Child node ids, in order.

final

components → List<ComponentSpec>

The components attached to this node.

final

excludeFromWindingParity ↔ bool

Whether this node's mirror transform is excluded from winding-parity tracking. Set on handedness-adapter nodes (a scale(1, 1, -1) that converts between authoring spaces rather than mirroring content), so the renderer does not flip triangle winding under it.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

id → LocalId

This node's stable, document-scoped id.

final

instance ↔ PrefabInstanceSpec?

Non-null when this node is a prefab instance.

getter/setter pair

layers ↔ int

The render-layer bitmask (defaults to layer 0).

getter/setter pair

name ↔ String

A non-identifying label (used for animation binding and name lookup).

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

skin ↔ LocalId?

The skin bound to this node, or null.

getter/setter pair

transform ↔ TransformSpec

The node's local transform.

getter/setter pair

visible ↔ bool

Whether this node (and so its subtree) renders. Hidden nodes still realize and tick; only drawing is skipped.

getter/setter pair

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
