当我在 Facebook 上为我的 flutter 应用创建广告时，如何跟踪安装量？

问：

我创建了一个 flutter 应用程序并发布到 Play 商店，我通过支付广告费用在 Facebook 上推广该应用程序。问题是Facebook无法跟踪安装数量，所以我只做一个普通的广告。 如何集成Facebook SDK来跟踪FaceBBOK ADS的安装。请需要您的帮助...

import 'package:flutter_facebook_sdk/flutter_facebook_sdk.dart';

class MyAppState extends State<MyApp> {

    String _deepLinkUrl = 'Unknown';
    FlutterFacebookSdk? facebookDeepLinks;
    Future<void> initPlatformState() async {
        String? deepLinkUrl;
        try {
            facebookDeepLinks = FlutterFacebookSdk();
            facebookDeepLinks!.onDeepLinkReceived!.listen((event) {
                setState(() {
                    _deepLinkUrl = event;
                });
            });
            deepLinkUrl = await facebookDeepLinks!.getDeepLinkUrl;
            setState(() {
                _deepLinkUrl = deepLinkUrl!;
            });
        } on PlatformException {}
        if (!mounted) return;
    }
    @override
    void initState() {
        super.initState();
        initPlatformState();
    }
    Future<void> setAdvertiserTracking() async {
        await facebookDeepLinks!.setAdvertiserTracking(isEnabled: true);
    }

    @override

            builder: (_) => MaterialApp(

                    FirebaseAnalyticsObserver(analytics: analytics),
                ],
                home: SplashScreen(),
                theme: AppTheme.lightTheme,
                darkTheme: AppTheme.darkTheme,
                themeMode: appStore.isDarkMode ? ThemeMode.dark : ThemeMode.light,

                locale: Locale(appStore.selectedLanguage!.languageCode.validate(value:     
                DEFAULT_LANGUAGE)),
            ),
        );
