如何通过单击SliverAppbar颤动中的按钮来最小化SliverList

import 'package:flutter/material.dart';

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  bool isListMinimized = false;

  void toggleListMinimized() {
    setState(() {
      isListMinimized = !isListMinimized;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: CustomScrollView(
        slivers: <Widget>[
          SliverAppBar(
            title: Text('My App'),
            floating: true,
            snap: true,
            actions: <Widget>[
              IconButton(
                icon: Icon(Icons.arrow_downward),
                onPressed: toggleListMinimized,
              ),
            ],
          ),
          SliverList(
            delegate: SliverChildBuilderDelegate(
              (BuildContext context, int index) {
                return AnimatedContainer(
                  height: isListMinimized ? 0 : 100, // 根据最小化状态设置高度
                  color: Colors.blue,
                  child: ListTile(
                    title: Text('Item $index'),
                  ),
                  duration: Duration(milliseconds: 300),
                );
              },
              childCount: 10,
            ),
          ),
        ],
      ),
    );
  }
}

void main() {
  runApp(MyApp());
}
