RepeatAdapter class

Repeats an animation with timer-based pauses between runs.

Unlike an effect delay, pause is outside the controller timeline, so the controller does not tick while waiting. Remove the effect's delay when moving that wait here. Use initialDelay for the wait before the first run; Animate.delay and Animate.autoPlay do not control adapters.

Each direction counts as one run. With reverse and count: 2, the animation runs forward once, waits, then reverses once. count defaults to infinite; zero leaves the animation at zero without starting it. Pauses hold the value reached by the previous run.

period is the duration of each run, or the controller's duration when null. It must be positive. pause and initialDelay must be nonnegative. Pauses use wall-clock timers and are not scaled by Flutter's time dilation.

Keep the adapter instance across rebuilds to preserve playback. Replacing it restarts the sequence. While attached, the adapter controls playback; do not also set Animate.target / Animate.value or drive its controller directly. It never disposes the controller or changes its duration. Detaching cancels pending waits and stops a run that this adapter started.

Animate.onComplete fires normally when a forward run reaches one. Animate.onPlay is not called for adapter-driven playback.

final repeat = RepeatAdapter(pause: const Duration(seconds: 2));
// Within build:
// child.animate(adapter: repeat).shimmer(duration: const Duration(seconds: 1));
