SceneAnimationSpec class Widgets

Declares the playback state of one of a SceneModel's imported animations.

An immutable value: rebuild with different values and the widget applies the differences to the underlying AnimationClip as plain property writes, so weight and speed can be driven by ordinary Flutter animations (a TweenAnimationBuilder cross-fading two clips' weights, for example). Clips for the same name persist across rebuilds; a spec that disappears from SceneModel.animations stops its clip.

A one-shot spec (loop false) whose playing flips from false to true restarts from the beginning; a looping spec resumes.

Constructors

SceneAnimationSpec(String name, {bool playing = true, bool loop = true, double weight = 1.0, double speed = 1.0})

const

Properties

hashCode → int

The hash code for this object.

no setter, override

loop → bool

Whether the clip wraps at the end instead of pausing.

final

name → String

The imported animation's name.

final

playing → bool

Whether the clip advances. Pausing keeps the current playback time.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

speed → double

Playback rate multiplier (negative plays in reverse).

final

weight → double

Blend weight in [0, 1]; overlapping clips are weight-blended and normalized by the engine when the sum exceeds one.

final

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.
