Crash-free statistics monitor not working in Firebase Crashlytics in Flutter

Question

I tried to set-up Firebase Crashlytics in my Flutter application. Everything works and crashes are collected properly now except for one thing. Crash-free monitor is not working and I really can do nothing with that. I see this kind of message instead of data all the time:

1) pubspec.yaml contains following dependencies:

firebase_crashlytics: 0.1.2+4
firebase_core: 0.4.3+2
firebase_messaging: 6.0.9
firebase_analytics: 5.0.9

2) runner.dart

void run() async {
  // закрепляем ориентацию todo изменить на необходимое или убрать
  await SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);

  _initCrashlytics();
  _initLogger();
  _runApp();
}

void _runApp() {
  runZoned<Future<void>>(
    () async {
      runApp(App());
    },
    onError: Crashlytics.instance.recordError,
  );
}

void _initCrashlytics() {
  FlutterError.onError = Crashlytics.instance.recordFlutterError;
}

void _initLogger() {
  RemoteLogger.addStrategy(CrashlyticsRemoteLogStrategy());
  Logger.addStrategy(DebugLogStrategy());
  Logger.addStrategy(RemoteLogStrategy());
}

3) build.gradle (android)

classpath 'io.fabric.tools:gradle:1.31.2'

4) build.gradle (android/app)

apply plugin: 'io.fabric'
apply plugin: 'com.google.gms.google-services'

No errors in LogCat, no warnings, nothing. I see successful initialization message in logs every time application starts:

2020-01-10 12:27:32.691 23082-23082/ru.app.biz.client.android.debug I/FirebaseInitProvider: FirebaseApp initialization successful

I even tried to add Google Analytics dependency directly into my Android module but with no luck. Both Android and iOS applications are under this issue.

What am I doing wrong?

Solution 1

Finally, I found the answer. Google Analytics was disabled in my Firebase project settings and it caused issues with crash-free widget.

Here are steps to fix it:

1) Go to project settings in your Firebase project console;
2) Move to the "Integrations" tab;
3) Click "Enable" on Google Analytics widget and go through all necessary steps;
4) Wait a while to see the result.

Solution 2

I don't know exactly, but I see some problems in your settings:

1. There is no need to add firebase_core, firebase_analytics enough as google said:

2. You forgot to add classpath 'com.google.gms:google-services:4.3.0' to your build.gradle (android)

3. Maybe your project new and it doesn't have enough information to show.

When did you get this message image from? The Firebase documentation for setting up Flutter still says firebase-core is required: firebase.google.com/docs/flutter/setup?platform=android
