import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Center(
      child: Text(
        'Hello, world!',
        textDirection: TextDirection.ltr,
        textAlign: TextAlign.center,
        overflow: TextOverflow.ellipsis,
        style: TextStyle(fontWeight: FontWeight.bold),
      ),
    );
  }
}
