Extending

Extending animations is as simple as below. See the example repo for how to override the animation to achieve a lottery-like animation.

const lotteryEnterAnimationConfigCreator: EnterAnimationConfigCreator = (() => {
    return {
        ...defaultEnterAnimationConfigCreator,
        [AnimatedItemType.DIGIT]: () =>
            makeAnimation({
                translateY: {
                    from: 10,
                    to: 0,
                },
                duration: 150,
            }),
    };
})();

...

return (
    <AnimatedDigits
        value={usd}
        enterAnimationConfigCreator={customConfigCreator}
    />
)
