如何在flutter中实现此页面更改上的动画？使用changenotifierprovider

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

class AnimationModel extends ChangeNotifier {
  bool _isAnimating = false;

  bool get isAnimating => _isAnimating;

  void startAnimation() {
    _isAnimating = true;
    notifyListeners();
  }

  void stopAnimation() {
    _isAnimating = false;
    notifyListeners();
  }
}

ChangeNotifierProvider(
  create: (context) => AnimationModel(),
  child: YourPage(),
)

Consumer<AnimationModel>(
  builder: (context, animationModel, child) {
    return YourAnimatedWidget(
      isAnimating: animationModel.isAnimating,
      // 其他参数
    );
  },
)

class YourAnimatedWidget extends StatelessWidget {
  final bool isAnimating;
  // 其他参数

  YourAnimatedWidget({required this.isAnimating, /* 其他参数 */});

  @override
  Widget build(BuildContext context) {
    if (isAnimating) {
      // 执行动画效果
      return AnimatedContainer(
        // 动画参数
      );
    } else {
      // 不执行动画效果
      return Container(
        // 静态效果
      );
    }
  }
}
