How can I run this plugin only for iOS?

[GrupoDO]

I have an app that runs on Android and iOS. How can I run this plugin only in iOS?

This is not working, it runs in Android too:

void main() async{
    WidgetsFlutterBinding.ensureInitialized();
	
	if(Platform.isIOS){
		print('START BACKGROUND SERVICE');
		await initializeService();
	}


    runApp(App(title: Config.appName, navigatorKey: navigatorKey));
}

Future<void> initializeService() async {
    final service = FlutterBackgroundService();
    await service.configure(
        androidConfiguration: AndroidConfiguration(
            // this will executed when app is in foreground or background in separated isolate
            onStart: (){},
            // auto start service
            autoStart: true,
            isForegroundMode: false,
        ),
        iosConfiguration: IosConfiguration(
            // auto start service
            autoStart: true,

            // this will executed when app is in foreground in separated isolate
            onForeground: onStart,

            // you have to enable background fetch capability on xcode project
            onBackground: onIosBackground,
        ),
    );
}

// to ensure this executed
// run app from xcode, then from xcode menu, select Simulate Background Fetch
void onIosBackground() async{
    WidgetsFlutterBinding.ensureInitialized();
    //code
}

void onStart() {
    WidgetsFlutterBinding.ensureInitialized();
    final service = FlutterBackgroundService();
    //code
}
