Demo Code

This example divides the available space into three (horizontally), and places text centered in the first two cells and the Flutter logo centered in the third.

import 'package:flutter/material.dart';

class RowDemo extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    // Return Material widget
    return Material(
      child: Row(
        children: <Widget>[
          Expanded(
            child: Text('Deliver features faster', textAlign: TextAlign.center),
          ),
          Expanded(
            child: Text('Craft beautiful UIs', textAlign: TextAlign.center),
          ),
          Expanded(
            child: FittedBox(
              fit: BoxFit.contain, // otherwise the logo will be tiny
              child: const FlutterLogo(),
            ),
          ),
        ],
      ),
    );
  }
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    // MaterialApp Widget
    return MaterialApp(
      title: 'Row Demo',
      home: RowDemo(),
    );
  }
}

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