title: How to show a widget along a ListView on the same screen in Flutter?
body: <p>I'm trying to build a very simple ToDo app. It consists of a <code>TextField</code> and a <code>Button</code> (a form) on the top of the screen that allow the user to add items to the <code>ListView</code> that is just under the <code>TextField</code>.</p>
  
  <p>I'm capable to display the <code>TextField</code> and the <code>Button</code>, and I'm also capable to display a <code>ListView</code>, but when I try to display both at the same time, the screen is empty.</p>
  
  <p>Am I missing something? I try to display the ListView into a Column widget but it looks like it doesn't work.</p>
  
  <p>Here is my short code without the form:</p>
  
  <pre><code>import 'package:flutter/material.dart';
  
  void main(){
    runApp(MyApp());
  }
  
  class MyApp extends StatelessWidget{
    @override
    Widget build(BuildContext context){
      return MaterialApp(
        title: "Mon app",
        home: Scaffold(
          appBar: AppBar(
            title: Text("My app")
          ),
          body: Column(
            children: &lt;Widget&gt;[
              ListView(
            children: &lt;Widget&gt;[
              ListTile(
                leading: Icon(Icons.map),
                title: Text('Map'),
              ),
              ListTile(
                leading: Icon(Icons.photo_album),
                title: Text('Album'),
              ),
              ListTile(
                leading: Icon(Icons.phone),
                title: Text('Phone'),
              ),
            ],
          )
            ])),
        );
    }
  }
  </code></pre>
  
  <p>Thanks!</p>
