Flutter: Missing google_app_id. Firebase Analytics disabled

I want to send a notification from a device to another but when I sent it I got in the receiver device :
D/FLTFireMsgReceiver( 8876): broadcast received for message
E/FA ( 8876): Missing google_app_id. Firebase Analytics disabled. See ...
I searched in the internet but no solution works from me so I add all the verification that I found that they need to be :
In the ProjectName/android/app/Build.gradle :
In the ProjectName/android/Build.gradle :
And I added the google-services.json in the path "ProjectName/android/app/"

The problem is the API Firebase Analytics is not installed so if you need to install it and activate it :
You must follow Literally the SDK setup and configuration of google:
Then restart your Pc or Mac.

Firebase In App Messaging PERMISSION_DENIED

I did setup for firebase in App messaging. Created campaign and my app can't deliver it.
In logcat I got following logs

Setup
Android studio 3.3.1
com.google.firebase:firebase-inappmessaging-display:17.0.5
com.google.firebase:firebase-core:16.0.7
Firebase in app messaging API enabled in Google Cloud Console
What could be reason of?

The reason of the issue was restriction on API key for Android app. So InAppMessaging API was enabled for the whole project but it also require add InAppMessaging API to the specific platform API key restriction.

you have to add the firebase InApp Messaging permission to your Google Cloud API, can be done from the Google Cloud Console

Firebase Crashlytics not reporting crashes when manually enabled

Crashlytics works just fine without opt-in reporting. But it stops reporting anything as soon as I set up opt-in reporting according to the tutorial.
Specifically, I added the following content to AndroidManifest.xml
<meta-data
android:name="firebase_crashlytics_collection_enabled"
android:value="false" />
And I added the following into the onCreate:
Fabric.with(this, Crashlytics())
With a debugger, I am sure that the above line has been executed.
However, nothing is reported to the Crashlytics. Instead, the logger gives the following,
D/Fabric: Falling back to Crashlytics key lookup from Manifest
D/Fabric: Falling back to Crashlytics key lookup from Strings
D/Fabric: Generating Crashlytics ApiKey from google_app_id in Strings
D/Fabric: Using AdvertisingInfo from Preference Store

D/Fabric: Could not get parcel from Google Play Service to capture Advertising limitAdTracking
D/Fabric: AdvertisingInfo not present
D/Fabric: Asychronously getting Advertising Info and storing it to preferences
I have noticed this interesting line: D/CrashlyticsCore: Crashlytics is disabled, because data collection is disabled by Firebase. which is probably the cause of the issue. Yet I can't find any information about this log.

There is an issue with Firebase Crashlytics 2.9.7 preventing opt-in reporting as described in the documentation to work: the start of Crashlytics from code will not be performed.
For the time being downgrading to 2.9.6 will enable your code to work properly.

Please follow this answer

For those wish to use crashlytics for their android app who haven't been using crashlytics of fiber.io, there are certain changes in the way you FirebaseApp is initialized which you will find in the above link.

Use following dependencies for android.
Paste it into build.gradle app:
implementation('com.crashlytics.sdk.android:crashlytics:2.9.6#aar') {
transitive = true
}
Upgrade it from 2.9.5 to 2.9.6.
It works for me.

Add this line into Application class
Fabric.with(this, Crashlytics())

Crashlytics 2.9.8 has been released which fixes the bug. I've tested to confirm. The changelog:
2.9.8 December 21, 2018
Fixed bug with firebase_crashlytics_collection_enabled flag that erroneously disabled data collection under some circumstances.

Initialization of app is not mentioned anywhere to get crashlytics report on our console!
Step 1. First follow the official doc's link to include all dependencies as it is given there and setup your firebase app through firebase console.
Step 2. Now do the following initialization in your base application class or base activity class.
FirebaseApp.initializeApp(getApplicationContext());
FirebaseCrashlytics.getInstance().setCrashlyticsCollectionEnabled(true);
Now clean you project and do some force crash for few times, you should be able to see your crashlytics report on your firebase console

FirebaseAuthInvalidCredentialsException ERROR_CUSTOM_TOKEN_MISMATCH

I have problems with Firebase Phone Auth.
Previously I used debug version and firebase account of user A. Then, we made publication on play market and it stopped sending sms.
I remove this project to another firebase acc that belongs to play services account owner. Created app, correctly fill in app id, connected it with play market app and then got json file from firebase and placed it in project.
When call to sendSms, nothing happpens (I did not change realization, only moved project from one acc to another)

ERROR_CUSTOM_TOKEN_MISMATCH
We never used custom keys. Just an example from git hub with no customization over it.
How to fix it?

I agree the error code is confusing. But the error message is key here: "App ID does not match requested project. " The same app used to obtain the phone auth credential should be the one used to sign in with it. That is why you are getting the error. It seems like you are getting the phone auth credential with one application and then signing in with that credential using another app.

I think you are testing your project with a normal .apk in your mobile or in the emulator. If you want to test your project for mobile authentication you have to provide your mobile number in the firebase mobile authentication in sing-in-method. Testing the mobile number(Optional mobile number) by which you want to test. Or you make a signed .apk and then try it again I think it will work fine.

Firebase Analytics events don't show up (Android)

I have an issue with Firebase Analytics. It basically boils down to the fact that nothing is registered; I have no data in my analytics page in the console.
I noticed today that when I want to send a push notification and I set a filter for the version number of my app, it shows "No versions available for this app". However, my iOS version of the app IS showing a version number in the dropdown list.
Does anyone have an idea what the issue is?
Some other issues I'm still experiencing:
"Firebase API initialization failure." IncompatibleClassChangeError ContextCompat.getNoBackupFilesDir() -> InvocationTargetException
Failed to load module descriptor class: Didn't find class "com.google.android.gms.dynamite.descriptors.com.google.firebase.auth.ModuleDescriptor"
Many thanks in advance.

the failed to load is not the problem, i have it too when using firebase-invites and i found this (Failed to load module descriptor class: Didn't find class "com.google.android.gms.dynamite.descriptors.com.google.firebase.auth.ModuleDescriptor")
the "Firebase API initialization failure." IncompatibleClassChangeError ContextCompat.getNoBackupFilesDir() -> InvocationTargetException
was fixed by updating the google services in the device
