How do I close my Flutter app programmatically on iOS?

I want to close my Flutter my app programmatically, I have tried all available solutions they work pretty well for Android but do not work for iOS.

Below code works well for Android but not for iOS

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: GestureDetector(
              onTap: () {
                Future.delayed(const Duration(milliseconds: 2000), () {
                  SystemNavigator.pop();
                  print('object'); 
                });

                
              },
              child: Text('Restart')),
        ),
      ),
    );
  }
}
