如何在flutter应用程序中设置大数字的格式？

import 'package:flutter/material.dart';
import 'package:intl/intl.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    // 设置大数字的格式
    var number = 1000000;
    var formattedNumber = NumberFormat.compact().format(number);

    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Number Formatting'),
        ),
        body: Center(
          child: Text(
            'Formatted Number: $formattedNumber',
            style: TextStyle(fontSize: 24),
          ),
        ),
      ),
    );
  }
}
