SceneNode class sealed

Properties

bindings → Map<String, SceneBinding>
Where each property's value comes from, when it is not a literal: property key → SceneBinding.
final
borderColor ↔ SceneColor?
A line around the node, or none. Two fields rather than one value, because the file's vocabulary is flat named arguments and a Border(...) would be a construct the grammar does not have.
getter/setter pair
borderWidth ↔ double
getter/setter pair
children → List<SceneNode>
no setter
corner ↔ double
getter/setter pair
corners ↔ SceneCorners
The corner radii. corner reads and writes them as one number — what they are for most nodes.
getter/setter pair
fill ↔ SceneColor?
getter/setter pair
fx → Map<(Object, String), Object>
The evaluated plane: per-frame contributions composed OVER the authored values above, keyed by (writer, property) in writer-stack order — the order is normative (× does not bit-commute). Motion lanes and app Effects write here; Save never reads it; a cancelled writer clears its own entries and the authored value was never touched.
final
hashCode → int
The hash code for this object.
no setterinherited
height ↔ double?
getter/setter pair
heightFills → bool
no setter
maxHeight ↔ double?
getter/setter pair
maxWidth ↔ double?
getter/setter pair
measured ↔ SceneRect?
Laid-out rect in artboard coordinates, swept after each frame by whichever renderer measured it.
getter/setter pair
minHeight ↔ double?
getter/setter pair
minWidth ↔ double?
Bounds on the laid-out size, when a node has them: a card no narrower than its title, a column no wider than a line of reading. Null is no bound.
getter/setter pair
name ↔ String
The node's identity — the field name in the file, and SOURCE-LEVEL ONLY. A compiled scene leaves it empty: Dart has no field-name reflection, and at runtime a node's identity is the object, which is what makes scene.headline a typed reference rather than a lookup. The editor, which parsed the source, is what fills this in.
getter/setter pair
opacity ↔ double
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
typeName → String
no setter
visible ↔ bool
Whether the node is drawn and laid out at all. Not opacity zero: a hidden node takes no room in a row, and a column closes over it. The boolean a component most often exposes — show the badge, hide the footer — which is why it is a property and not an effect.
getter/setter pair
width ↔ double?
Size along each axis, three-valued in one field:
getter/setter pair
widthFills → bool
Whether this node takes what the parent gives along each axis.
no setter
x ↔ double
getter/setter pair
y ↔ double
getter/setter pair

Methods

animate({MotionTrack? opacity, MotionTrack? translateX, MotionTrack? translateY, MotionTrack? scale, MotionTrack? rotate}) → AnimateGroup

Available on SceneNode, provided by the SceneNodeAnimate extension

clearFxWriter(Object writer) → void
effect() → Effect
Mint an app-side fx writer. Handles are the only app surface — two independent effects on one property compose instead of colliding, and clearing one leaves the others (sketch 25).
fxRendered(String prop) → Object
The composed value the renderer should draw: authored base folded with every contribution through the derived operator table — opacity and scale multiply, translations and rotation add, everything else replaces in stack order.
hasFx(String prop) → bool
Whether any writer currently contributes to prop — the renderer asks this where the authored value's absence means something (a null fill draws no decoration; a composed fill draws one).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeFx(Object writer, String prop) → void
toString() → String
A string representation of this object.
inherited
writeFx(Object writer, String prop, Object value) → void

Operators

operator ==(Object other) → bool
The equality operator.
