TweenAnimation<T> class

Tween animation for interpolating values.

Fields are non-final so instances can be reconfigured after being acquired from an ObjectPool, avoiding per-tween allocation overhead.

TweenAnimation({required T start, required T end, required T lerp(T start, T end, double t), required void onUpdate(T value), required double duration, Easing easing = Easings.linear, bool loop = false, VoidCallback? onComplete}): Create a tween animation

currentTime ↔ double: Current time in the animation

easing ↔ Easing: Easing function
getter/setter pair
end ↔ T: End value
getter/setter pair
hashCode → int: The hash code for this object.
no setterinherited
isComplete → bool: Check if animation is complete
no setterinherited
isPaused ↔ bool: Whether animation is paused

lerp ↔ T Function(T start, T end, double t): Interpolation function
getter/setter pair
loop ↔ bool: Whether animation loops (non-final to allow pool reconfiguration).
getter/setter pairinherited
normalizedTime → double: Get normalized time (0.0 to 1.0)
no setterinherited
onComplete ↔ VoidCallback?: Callback when animation completes
getter/setter pairinherited
onUpdate ↔ void Function(T value): Callback with current value
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
speed ↔ double: Animation speed multiplier
getter/setter pairinherited
start ↔ T: Start value
getter/setter pair

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
pause() → void: Pause the animation
inherited
play() → void: Play the animation
inherited
reset() → void: Reset all mutable state so the animation can be replayed or reused from an ObjectPool.
inherited
stop() → void: Stop and reset
inherited
toString() → String: A string representation of this object.
inherited
update(double deltaTime) → void: Update the animation
inherited
updateAnimation(double deltaTime) → void: Override this to implement animation logic
