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('Dynamic ListViews')),
        body: Column(
          children: [
            Expanded(
              child: ListView.builder(
                itemCount: 20,
                itemBuilder: (context, index) {
                  return ListTile(title: Text('Item $index'));
                },
              ),
            ),
            Expanded(
              child: ListView.builder(
                itemCount: 15,
                itemBuilder: (context, index) {
                  return ListTile(title: Text('Item $index'));
