For anyone having a problem with this in the future. Here is what you need to do:

flutter pub add simple_animations && flutter pub get

for the fade_animation file you can use my modified version which supports the new version of simple_animations package:

import 'package:flutter/material.dart';
import 'package:simple_animations/simple_animations.dart';

class FadeAnimation extends StatelessWidget {
  final double delay;
  final Widget child;

  const FadeAnimation(this.delay, this.child, {super.key});

  @override
  Widget build(BuildContext context) {
    final tween = MovieTween()
      ..scene(
        begin: const Duration(milliseconds: 0),
        duration: const Duration(milliseconds: 500),
      ).tween('opacity', Tween<double>(begin: 0.0, end: 1.0)).tween(
          'translateY', Tween<double>(begin: -30.0, end: 0.0),
          curve: Curves.easeOut);

    return PlayAnimationBuilder<Movie>(
      delay: Duration(milliseconds: (500 * delay).round()),
      duration: tween.duration,
      tween: tween,
      builder: (context, value, child) {
        return Opacity(
          opacity: value.get('opacity'),
          child: Transform.translate(
            offset: Offset(0, value.get('translateY')),
            child: child,
          ),
        );
      },
      child: child,
    );
  }
}
