How to set user Id and propeties in Firebase Analytics - Flutter

Question

• Goal: To save user ID and their properties, as he/she interacts with the flutter application.
• Problem: Events are getting logged but i cant see user id and properties. I noticed it initially (that user id and properties arre not being logged) while working in debug mode, and then I also waited for 24-48 hours to check in the dashboard but no details for userId.
• Documentation link: https://firebase.google.com/docs/analytics/userid#dart
• and Yes the properties that I am trying to save in analytics, I have defined them in Custom definitions under User scope.
• Code:

import 'package:firebase_analytics/firebase_analytics.dart';

class AnalyticsClass {
  static final AnalyticsClass _singleton = AnalyticsClass._internal();
  late FirebaseAnalytics fa = FirebaseAnalytics.instance;

  factory AnalyticsClass() {
    return _singleton;
  }

  AnalyticsClass._internal();

  buttonTap(id, name) async {
    await fa.logEvent(name: 'button_tap');
  }

  setUser(String id, name) async {
    await fa.setUserId(id: id);
    await fa.setUserProperty(name: 'referral', value: "test new : $name");
  }

  resetUser() async {
    await fa.setUserId(id: null);
    await fa.setUserProperty(name: 'referral', value: null);
  }
}

If you're using the setUserId() in Firebase, this does not show up in the Analytics reports due to privacy concerns. What you can do is to export your data to BigQuery . This will allow you to query your raw data as well as build custom reports via Data Studio . You may also consider using the User explorer in Google Analytics Dashboard which will help you gain more insight on the behavior of your individual users.
