Firebase analytics is not updating screen name after recent update from my Flutter App

My app is developed in flutter and running in IOS and Android for past one year. After recent update in 2022 March 1st week I am not getting updated new user count or the screen name of the pages visited by user only from Android. I am using Mac M1. If I use iphone simulator the screen name appears in analytics (i have suffixed 'ios' and current time to screen name to verify this). But if I use Android simulator page views are not getting updated (probably everything showing under 'not set' or 'others'.

I have added this code in Android manifest.xml as some suggested. but still not working.

This is the code in my initial page.

 FirebaseAnalytics analytics = FirebaseAnalytics.instance;
    FirebaseAnalyticsObserver observer =
    FirebaseAnalyticsObserver(analytics: analytics) ;
    String _message = '';
    void setMessage(String message) {
      // setState(() {
      _message = message;
      myMessage = message;
      // });
    }
    Future<void> _testSetCurrentScreen() async {
      await analytics.setCurrentScreen(
        screenName: myScreenName,
        screenClassOverride: 'AnalyticsDemo',
      );
      setMessage('setCurrentScreen succeeded');
      myMessage = "loaded $myScreenName" ;
    }
    _testSetCurrentScreen();
       print("1476 $myMessage '_' $myMessage");
