To create Flutter animations without setState, use an abstract AnimationWidget class that handles the animation ticker internally. This approach leverages SingleTickerProviderStateMixin for frame-by-frame updates, eliminating manual state management and reducing boilerplate.

The best way to improve Flutter animation performance is abstracting the animation ticker so the UI updates efficiently without explicit setState calls. This prevents unnecessary widget rebuilds, ensuring smooth visual effects with lower overhead.

Yes, SingleTickerProviderStateMixin is required to build these custom Flutter animation widgets. The abstract AnimationWidget class integrates it seamlessly to provide efficient frame-by-frame ticker updates for your UI animations.

To implement a custom animation class in Flutter, you extend the abstract AnimationWidget class. This base class manages the ticker and state updates automatically, allowing you to focus on defining complex, smooth visual effects with less code.

Your Flutter animation causes excessive rebuilds because it relies on manual setState calls. By switching to an abstract AnimationWidget that handles the ticker internally, you avoid unnecessary rebuilds and achieve efficient frame-by-frame UI updates.
