🐛 [firebase_analytics] Missing google_app_id. FIrebase Analytics disabled.

[JCKodel]

Bug report

Describe the bug
Firebase won't work by default in Flutter.

I need to manually add those lines on my android/build.grade:

buildscript {
  dependencies {
    classpath 'com.google.gms:google-services:4.3.15'

and then apply it on android/app/build.gradle:

plugins {
  id "com.google.gms.google-services"

Without those additions, the following error is displayed on the console:

E/FA: Missing google_app_id. Firebase Analytics disabled. See https://useless-link

But 4.3.15 is not the latest version. Documentation says it is 4.4.0. Problem is: with 4.4.0, the same error appears and analytics won't work.

In other words:

1. Without any intervation, firebase_analytics doesn't work
2. Using com.google.gms:google-services:4.3.15 does work
3. Using com.google.gms:google-services:4.4.0 doesn't work

Steps to reproduce

Steps to reproduce the behavior:

1. Create a project with firebase_analytics and follow the documentation
2. Log some event

Expected behavior

To work, without any kind of warning, especially about deprecated APIs!!!!

same here, double confirmed on clean project and existing project.

[danagbemava-nc]

Hi @JCKodel, did you do the setup with the flutterfire_cli. If so, can you try invertase/flutterfire_cli#210 (comment) to see if it is setup properly?

[JCKodel]

@danagbemava-nc

Attempt 1:

• I've removed any build.gradle additions (since the documentation says nothing about add something there)
• I've updated flutterfire_cli to 0.3.0.dev-18
• I've run flutterfire configure again
• I've run flutter clean && flutter pub get

Same error (Missing google_app_id. Firebase Analytics disabled. See https://goo.gl/NAOOOI)

Attempt 2:

• Same as previous, but I've added latest com.google.gms:google-services (4.4.0) in build.gradle as dependencies { classpath 'com.google.gms:google-services:4.4.0' }
• Also added plugins { id "com.google.gms.google-services" }
• flutter clean && flutter pub get

Same error (Missing google_app_id. Firebase Analytics disabled. See https://goo.gl/NAOOOI)

Nothing has changed.

Reverting it to classpath 'com.google.gms:google-services:4.3.15', works as intended.

Also, why one build.gradle uses buildscript but the other uses plugins??? Documentation says plugins is the new way and buildscript is deprecated =\

[danagbemava-nc]

Hi @JCKodel, what google-service version is generated by the cli?
Does it work with that version?

[JCKodel]

Hi @JCKodel, what google-service version is generated by the cli? Does it work with that version?

And how do I check this?

[danagbemava-nc]

The version will be in your build.gradle file surrounded by START: Flutterfire configuration

[JCKodel]

The version will be in your build.gradle file surrounded by START: Flutterfire configuration

Flutterfire doesn't touch build.gradle.

I've created a new Flutter project, then added on a git repository and commit it.

So, I ran flutter pub add firebase_analytics firebase_core, then flutterfire configure.

These are the changes made by those two commands:

Build.gradle (both of it) weren't touched.

[danagbemava-nc]

That's odd. Can you try using flutterfire_cli 0.3.0-dev.19 to see if it generates the configuration for you? You can install that version by running dart pub global activate flutterfire_cli 0.3.0-dev.19 --overwrite

Using 0.3.0-dev.19 in a new flutter project, my android/app/build.gradle now has

plugins {
    id "com.android.application"
    // START: FlutterFire Configuration
    id 'com.google.gms.google-services'
    // END: FlutterFire Configuration
    id "kotlin-android"
    id "dev.flutter.flutter-gradle-plugin"
}

& android/build.gradle has

dependencies {
        // START: FlutterFire Configuration
        classpath 'com.google.gms:google-services:4.3.15'
        // END: FlutterFire Configuration
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }

[JCKodel]

TL;DR: It works.

This version of flutterfire adds the 4.3.15 version (which seems to work).

I had to clean my flutter pub cache, otherwise, it would not recognize import 'package:firebase_core/firebase_core.dart';

After that, this code runs without any kind of warning (which I assume it worked)

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

  FirebaseAnalytics.instance.logAppOpen();;
  runApp(const MyApp());
}

Thanks for letting us know, @JCKodel 🙏. There was a fix in flutterfire_cli 0.3.0-dev.19 for the android build.gradle updates.
