StillKeyframe<T> class

A keyframe that holds a constant value without animating.

This keyframe maintains a static value for its duration. If value is null, it uses the ending value from the previous keyframe.

Type Parameters

• T - The type of value to hold.

Overview

Use StillKeyframe to create pauses or delays in timeline animations where the value remains constant for a period of time.

Example

final timeline = TimelineAnimation<double>(
  keyframes: [
    AbsoluteKeyframe(Duration(milliseconds: 100), 0.0, 1.0),
    StillKeyframe(Duration(milliseconds: 200)), // Hold at 1.0 for 200ms
    RelativeKeyframe(Duration(milliseconds: 100), 0.0), // Back to 0.0
  ],
);
