main.dart

import 'package:flutter/material.dart';

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

/// main application widget.
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  static const String _title = 'Flutter Tutorial';

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      title: _title,
      home: MyStatefulWidget(),
    );
  }
}

/// stateful widget that the main application instantiates
class MyStatefulWidget extends StatefulWidget {
  const MyStatefulWidget({Key? key}) : super(key: key);

  @override
  State<MyStatefulWidget> createState() => _MyStatefulWidgetState();
}

/// private State class that goes with MyStatefulWidget
class _MyStatefulWidgetState extends State<MyStatefulWidget> {

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Row Widget Tutorial'),
      ),
      body: Row(
        children: const <Widget>[
          Text('Text 1', style: TextStyle(fontSize: 24.0,), ),
          Icon(
            Icons.beach_access,
            color: Colors.pink,
            size: 90.0,
          ),
          Text('Text 2', style: TextStyle(fontSize: 20.0),),
          Icon(
            Icons.audiotrack,
            color: Colors.green,
