          builder: (context, child) {
            final animationPercent = Curves.elasticOut.transform(
              _buttonInterval.transform(_staggeredController.value),
            );
            final opacity = animationPercent.clamp(0.0, 1.0);
            final scale = (animationPercent * 0.5) + 0.5;

            return Opacity(
              opacity: opacity,
              child: Transform.scale(scale: scale, child: child),
            );
          },
          child: ElevatedButton(
            style: ElevatedButton.styleFrom(
              shape: const StadiumBorder(),
              backgroundColor: Colors.blue,
              padding: const EdgeInsets.symmetric(horizontal: 48, vertical: 14),
            ),
            onPressed: () {},
            child: const Text(
              'Get started',
              style: TextStyle(color: Colors.white, fontSize: 22),
