🐛 [firebase_analytics] Not working on Android with manual or Dart only initialization

[asterion2nd]

Bug report

Describe the bug
Firebase Analytics does not work on Android after running flutterfire configure and either using
Firebase.initializeApp()
or
Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform)

I then set
final analyticsInstance = FirebaseAnalytics.instance;
And send events using:
await analyticsInstance?.logEvent(name: eventName, parameters: parameters,);

No error messages shows up. At the same time, Analytics works on iOS and Firebase Cloud Messaging works on both Android and iOS.

Steps to reproduce

Steps to reproduce the behavior:

1. Add to pubspec.yaml:
   firebase_core: ^2.14.0
   firebase_messaging: ^14.6.4
   firebase_analytics: ^10.4.3

2. flutterfire configure

3. Select project

4. Check if android/app/google-services.json was created

5. Check if lib/firebase_options.dart was created

6. Check if android/build.gradle has classpath 'com.google.gms:google-services:4.3.10'

7. Check if android/app/build.gradle has apply plugin: 'com.google.gms.google-services'

8. Try to initialize Firebase using either
   Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
   or
   Firebase.initializeApp();

9. Connect android device

10. Run $ adb shell setprop debug.firebase.analytics.app <package_id>

11. Build and run the app

12. Check Debug View in Firebase

13. Check if Analytics data from Android deviced get saved after releasing the app.

Expected behavior

Debug View in Firebase should record events from an Android device after installing the app using flutter run or "Run without debugging in VS Code"

Analytics property should record data from Android devices running the latest version published to Play Store (works for iOS devices).

Additional context

pubspec.yaml:
environment:
sdk: ">=2.12.0 <3.0.0"
firebase_core: ^2.14.0
firebase_messaging: ^14.6.4
firebase_analytics: ^10.4.3

android/app/build.gradle:
$ flutterfire configure added the following:
// START: FlutterFire Configuration
apply plugin: 'com.google.gms.google-services'
// END: FlutterFire Configuration

which initially looked like:
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

Then I tried moving apply plugin: 'com.google.gms.google-services' to the bottom.

android/build.gradle:
dependencies {
classpath 'com.android.tools.build:gradle:7.1.2'
// START: FlutterFire Configuration
classpath 'com.google.gms:google-services:4.3.10'
// END: FlutterFire Configuration
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

Debug View
Executed
$ adb shell setprop debug.firebase.analytics.app <package_id>

And went to Debug View on Firebase. Nothing shows up.

The app is already in production but no Android data get saved.

Also, "android/app/google-services.json" is correct (FCM works on Android) and I double checked all values against my Firebase project.

I tried all workarounds on these threads and nothing seems to work:

Additional info:
If I use http requests provided by "Measurement Protocol (Google Analytics 4)":

import 'package:http/http.dart' as http;
import 'dart:convert' show jsonDecode;
import 'package:firebase_analytics/firebase_analytics.dart'
    show FirebaseAnalytics;

final url = "https://www.google-analytics.com/mp/collect?api_secret=<api_secret>&firebase_app_id=<app_id>

final body = {
      "app_instance_id": await FirebaseAnalytics.instance.appInstanceId,
      "events": [
        {
          "name": "test_event",
        }
      ]
    };
    
    await http.post(
      Uri.parse(url),
      body: jsonEncode(body),
    );

where
<app_id> matches with mobilesdk_app_id in google-services.json
and <api_secret> is generated through Analytics: Admin > Data Streams > choose your stream > Measurement Protocol > Create.

Events show up in real-time in Analytics.

You are not on latest version of the framework. Can you upgrade to latest (3.10.6) and run your scenario to check if the behavior still persist or not ?

Thanks for taking a look at this.

It still does not work.

I ran $flutter upgrade, re-installed dart pub global activate flutterfire_cli, ran $ flutterfire configure again after deleting all files it creates and removing its modifications to gradle.build files.

I also checked both Debug View and the realtime page of Analytics.

Also, I printed out the FirebaseApp instance and all parameters match with those in google-sevices.json.

Future main() async {
WidgetsFlutterBinding.ensureInitialized();

  final x = Platform.isIOS
      ? await Firebase.initializeApp(
          options: DefaultFirebaseOptions.currentPlatform)
      : await Firebase.initializeApp();

  print(x.options.asMap);
  ...
  }
  
{apiKey: ***, appId: ***, messagingSenderId: ***, projectId: ***, authDomain: null, databaseURL: https://***, storageBucket: ***.appspot.com, measurementId: null, trackingId: null, deepLinkURLScheme: null, androidClientId: null, iosClientId: null, iosBundleId: null, appGroupId: null}

Thanks for the update and patience. Can you try the plugin example with your setup and see if using it, you still get the reported behavior or not ?

@darshankawar
Thanks for your help. Based on the example you shared, I adjusted all sdk and package versions and other small details.
It's working know.

Please go ahead and close this issue.
