CueTimeline class abstract

Base class for timeline implementations.

Defines the interface for managing and coordinating animation tracks. Subclasses handle the actual track management, progress synchronization, and animation lifecycle.

Properties

defaultConfig → TrackConfig
Default track configuration.
no setter
forwardDuration → double
Forward animation duration (max across all tracks).
no setter
hashCode → int
The hash code for this object.
no setterinherited
progress → double
Overall timeline progress (0-1).
no setter
reverseDuration → double
Reverse animation duration (max across all tracks).
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
status → AnimationStatus
Current animation status. Represents the overall status across all tracks (forward, reverse, completed, dismissed).
no setter
tolerance ↔ Tolerance
How close to the actual end of the simulation a value at a particular time must be before isDone considers the simulation to be "done".
getter/setter pairinherited
tracks → Map<TrackConfig, TrackEntry>
All active tracks mapped by configuration.
no setter

Methods

addEventListener<E extends T>(void listener(E)) → EventDisposer
Add an event listener that will be called with the event data when fireEvent is called.
inherited
addStatusListener(AnimationStatusListener listener) → void
Adds a status listener to be notified of animation state changes.
buildTrack(TrackConfig config) → CueTrack
Builds a track instance for a configuration.
dispose() → void
Disposes timeline resources.
dx(double time) → double
The velocity of the object in the simulation at the given time.
inherited
fireEvent(TimelineEvent data) → void
Fire an event with data to all event listeners
inherited
isDone(double time) → bool
Whether the simulation is "done" at the given time.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
obtainDefaultTrack() → (CueTrack, ReleaseToken)
Gets or creates the default track.
obtainTrack(TrackConfig config) → (CueTrack, ReleaseToken)
Gets or creates a track for the given configuration.
prepare({required bool forward, double? from, double? target, double? velocity}) → void
Prepares timeline for animation playback.
prepareForRepeat(RepeatConfig config) → void
Prepares timeline for repeating animations.
release(ReleaseToken token) → void
Releases a track obtained via obtainTrack or obtainDefaultTrack.
removeStatusListener(AnimationStatusListener listener) → void
Removes a previously added status listener.
reset() → void
Resets timeline to initial state.
setProgress(double value, {bool forward = true, bool forceLinear = false}) → void
Sets timeline progress (0-1).
toString() → String
A string representation of this object.
inherited
willAnimate({required bool forward}) → void
Fires pre-animation event.
x(double time) → double
The position of the object in the simulation at the given time.

Operators

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