TimelineAnimatable<T> class

An Animatable wrapper for TimelineAnimation with explicit duration.

This class adapts a TimelineAnimation to work with a specific total duration, scaling the animation to fit within that time frame.

Type Parameters

• T - The type of value being animated.

Overview

TimelineAnimatable is typically created via TimelineAnimation.drive or TimelineAnimation.withTotalDuration to bind a timeline to a controller.

Example

final controller = AnimationController(
  vsync: this,
  duration: Duration(seconds: 2),
);
final animatable = timeline.drive(controller);
