AbsoluteKeyframe<T> class

A keyframe that animates between explicit start and end values.

This keyframe interpolates from a specified from value to a to value over its duration, independent of previous keyframes.

Type Parameters

• T - The type of value to animate.

Overview

Use AbsoluteKeyframe when you want complete control over both the start and end values of a keyframe, regardless of previous animation state.

Example

// Animate from 0.0 to 1.0 over 200ms
final keyframe = AbsoluteKeyframe<double>(
  Duration(milliseconds: 200),
  0.0,
  1.0,
);

Implemented types

• Keyframe<T>
