Firebase Analytics not logging events in Flutter despite correct setup.

[ctkqiang]

Environment

• Flutter version: [e.g. 3.22.0]
• Dart version: [e.g. 3.3.0]
• Android/iOS/Both: [e.g. Android only]
• Firebase SDK version: [e.g. firebase_analytics: ^10.10.0]

Problem

I've implemented event logging through both Firebase Analytics:

• Events are not visible in Firebase GA4 DebugView.
• No SDK initialization errors are thrown.
• logEvent() are both called with correct params , No null exceptions (confirmed via debug prints).

What I’ve Tried

• adb shell setprop debug.firebase.analytics.app com.my.app
• Confirmed Firebase project is initialized with google-services.json.
• Firebase events use non-null, lowercased parameter maps.
• Logging fallback prints confirm both Firebase log functions are called.
• No error in logs  but no visible events either.

My code example:

class SomeClass{

    static final FirebaseAnalytics _analytics = FirebaseAnalytics.instance;    
    ....
      static Future<void> init() async {
      await VFAnalytics._analytics.setAnalyticsCollectionEnabled(true);
    await VFAnalytics._analytics.setSessionTimeoutDuration(
      const Duration(minutes: 30),
    );
    await FirebaseAnalytics.instance.setAnalyticsCollectionEnabled(true);
      }
    
    await _analytics.logEvent(
      name: "eventid.btm_nav",
      parameters: { "item": "stocklist", "user_id": "1234", "version": "1.0.0" },
    );
    ....
    ....
}

and in my main.dart

Future<void> main() async {
      WidgetsFlutterBinding.ensureInitialized();
      await Firebase.initializeApp();
    
      await dotenv.load();
      await logger.checkServerAvailablility();
      
      await SomeClass.init();
    
     ...
 }

Dear Masters, what else do I missed?
