main.dart

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      title: 'Flutter Demo',
      home: Scaffold(
        body: SelectionArea(
          child: Text('This is selectable text'),
        ),
      ),
    );
  }
}
