TuiAnimationEffect class - animation_effect library

Constructors

TuiAnimationEffect({required Duration duration, EasingFunction easing = Easing.linear, Duration targetFrameInterval = Duration.zero}): Creates a TuiAnimationEffect with the required duration, easing, and optional targetFrameInterval.

duration → Duration: Total duration of the animation lifecycle.
final
easing → EasingFunction: Easing curve applied to progress over time.
final
hashCode → int: The hash code for this object.
no setterinherited
isActive → bool: Whether the animation is currently active (for backward compatibility).
no setter
isAnimating → bool: Whether the animation is currently running/animating (status is forward or reverse).
no setter
isVisible → bool: Whether the animation is visible (status is not dismissed).
no setter
onUpdate ↔ VoidCallback?: The callback to trigger widget repaints.
getter/setter pair
progress ↔ double: The eased progress of the animation, bounded strictly between 0.0 and 1.0.
getter/setter pair
rawProgress → double: The raw (uneased) progress of the animation, bounded strictly between 0.0 and 1.0.
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
status ↔ AnimationStatus: The current status of the animation.
getter/setter pair
targetFrameInterval → Duration: The target frame interval (e.g. Duration(milliseconds: 33) for 30 FPS). If set, the effect will throttle its repaint triggers to this interval. Defaults to Duration.zero (render on every tick/vsync).
final
triggerPoint ↔ Point<int>?: The local coordinate where the animation was triggered.
getter/setter pair

forward() → void: Starts running this animation forward.
interpolateColor(Color c1, Color c2, double t) → Color: Helper utility to interpolate between two discrete Color properties.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
paint(Buffer buffer, Rect area, Style baseStyle) → void: Performs direct rendering modifications to the relative buffer.
reset() → void: Resets the animation to its default dormant/dismissed state.
reverse() → void: Starts running this animation in reverse.
start(Point<int> clickPoint, VoidCallback onUpdate) → void: Starts the animation forward from the beginning.
stop() → void: Stops the animation and freezes it at the current progress.
tick() → bool: Advances the animation tick frame. Returns true if ticking should continue.
toString() → String: A string representation of this object.
