title: Expanded widget inside Column not expanded, instead it's got invisible
body: <p>I am trying to expand widget inside of Column widget but not able to make it expended.</p>
  
  <p>When giving constant height to parent widget, the layout will be rendered as expected. But as I remove the constant height layout is not as expected as I want to make Listview with it and I should not give a constant height to the widget which will be used as listview item.</p>
  
  <p>Below is my layout code.</p>
  
  <pre><code> import 'package:flutter/material.dart';
  
   void main() {
  
   runApp(MaterialApp(
  title: 'layout test',
  home: Layout_test_class(),
  ));
  
   }
  
  
  
  class Layout_test_class extends StatelessWidget {
  
  Widget cell() {
  
  return Container(
    color: Colors.yellow,
  //      height: 200, after un commenting this will work. but i want to make it without this
  
    child: Row(
      crossAxisAlignment: CrossAxisAlignment.end,
      mainAxisSize: MainAxisSize.max,
      children: &lt;Widget&gt;[
  
        Expanded(
          child: Column(
            mainAxisSize: MainAxisSize.max,
            crossAxisAlignment: CrossAxisAlignment.stretch,
            children: &lt;Widget&gt;[
  
              Expanded(
                child: Container(
                  color: Colors.green,
                  child: Text('apple z'),
                ),
              ),
  
              Container(
                color: Colors.red,
                child:Text('apple 2'),
              )
            ],
          ),
        ),
  
        Column(
          children: &lt;Widget&gt;[
            Container(
              color: Colors.black,
              width: 200,
              height: 200,
            ),
          ],
        ),
  
      ],
    ),
  
  );
  
  }
  
  @override
  Widget build(BuildContext context) {
  // TODO: implement build
  return Scaffold(
    appBar: AppBar(
      title: Text('title'),
    ),
    body: Center(
     child: ListView(
       children: &lt;Widget&gt;[
         cell(),
       ],
     )
    ),
  );
  }
  
  }
