android - Flutter：当我滚动到 NESTED ListView 的末尾时，我希望父 ListView 滚动

Question

以下代码实现了一个带有嵌套 ListView 作为子级之一的 ListView。

Web 构建的行为：当我向下滚动到嵌套 ListView 的底部时，它会导致父级滚动。

Android 构建的行为：当我向下滚动到嵌套 ListView 的底部时，它不会导致父级滚动。

为什么有区别？如何使 Android 构建的行为类似于 Web 构建？

谢谢

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Demo')),
        // body: CollapsingList(),
        body: NestedLists(),
      ),
    );
  }
}

class NestedLists extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ListView(
      children: [
        Container(color: Colors.red, height: 150.0),
        Container(color: Colors.purple, height: 150.0),
        Container(color: Colors.green, height: 150.0),
        Container(color: Colors.orange, height: 150.0),
        Padding(
          padding: const EdgeInsets.all(20.0),
          child: Container(
            height: 150,
            child: ListView(
