Flutter question: How to insert a column inside a row in Flutter

Issue

My aim is to reproduce this UI layout in Flutter:

So far I have produced a layout with the below code which is missing the green square below the yellow square in the middle of the screen. How can i include the green square below the yellow square and center them? Can this be done by inserting a column inside a row? Thanks.

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        backgroundColor: Colors.teal,
        body: SafeArea(
          child: Row(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: <Widget>[
              Container(
                width: 100.0,
                color: Colors.red,
              ),
              Container(
                width: 100.0,
                height: 100.0,
                color: Colors.yellow,
              ),
              Container(
                width: 100.0,
                color: Colors.blue,
              ),
            ],
          ),
        ),
      ),
    );
  }
}

Solution

Simply wrap the inner container with a Column widget.

Here you go

  import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        backgroundColor: Colors.teal,
        body: SafeArea(
          child: Row(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: <Widget>[
              Container(
                width: 100.0,
                color: Colors.red,
              ),
              Column(
                mainAxisAlignment:MainAxisAlignment.center ,
                children: <Widget>[
                  Container(
                    width: 100.0,
                    height: 100.0,
                    color: Colors.yellow,
                  ),
                    Container(
                    width: 100.0,
                    height: 100.0,
                    color: Colors.green,
                  ),
                ],
              ),
              Container(
                width: 100.0,
                color: Colors.blue,
              ),
            ],
          ),
        ),
      ),
    );
  }
}
