I have a problem with app flutter when I integrate firebase_messaging to receive notification in the background
when I debug I get this error :

Since you're running Flutter 2.0.1, you only need to configure the Flutter part of the firebase messaging plugin, and add your google-services.json files.
Read carefully the official documentation and you'll fix your problem :)
If you need a sample project showcasing how to implement the Firebase Notifications, you can take a look at this one

I'm integrating firebase authentication into my android project with firebase assistant. After integrating firebase auth, it adds a dependency implementation 'com.google.firebase:firebase-auth:21.0.1' . when I use this dependency app crashes on launch.
and this is the log cat error

after referring to my old projects I used the old dependency implementation 'com.google.firebase:firebase-auth:20.0.4' and now it's working fine.
Why is the latest dependency not working for me? I'm testing my app on android 10 device.
Also if I add the latest firestore dependency, the app crash on launch.
what's going wrong here?
I want to build an app with Ionic V3 for Android but I have an issue when I build it on release.

It seems to be caused by Crashlytics (which I don't even use) which is integrated within this package https://github.com/dpa99c/cordova-plugin-firebasex.
When I build the app in debug mode, I still have the exception but the build proceed until the end and I still can run it on my phone.
How can I prevent this issue ? Is there anyway to disable entirely Crashlytics so I don't have this exception anymore ?
Thanks
Ok, so it was all because of the JDK version. I ended up updating the JDK and everything worked perfectly.
I am been trying to implement multiple transactions to the same document in flutter application which is using firestore as a its database, but it is crashing the application. The same thing when it was implemented in native apps of Xcode or android studio this issue didn't occur for even once.
Is there any guide how to make multiple transactions successful in flutter firestore.
For Instance, if more than 1 user from different devices is making the transaction to the same document at the same time, the transaction fails and the app crashes.
How could this be resolved?
Firestore.instance.runTransaction((Transaction tx) async {
DocumentSnapshot postSnapshot = await tx.get(docRef);
if (postSnapshot.exists) {
await tx.update(docRef, <String, dynamic>{'likes': postSnapshot.data['likes'] + 1});
// print("transaction completed");
}
})

Link To the Issue
Caused by: java.lang.AssertionError: INTERNAL ASSERTION FAILED: A transaction object cannot be used after its update callback has been invoked.
It looks like the transaction is being used after it's been committed/canceled.
This is a known issue in the FlutterFire library, as recorded in this issue on the open-source repo.
There is a workaround mentioned in this comment. So you can either try to apply that to your case, propose a PR that fixes the bug, or wait until somebody else fixes it.
I'm seeing bunch of crashes inside Crashlitics which are coming from most recent Firebase 15.0.0 on attempt to get FirebaseRemoteConfig
Caused by java.lang.NullPointerException
Attempt to invoke virtual method 'void com.google.android.gms.internal.config.zzar.zzc(long)' on a null object reference
com.google.firebase.remoteconfig.FirebaseRemoteConfig. (Unknown Source)
com.google.firebase.remoteconfig.FirebaseRemoteConfig.getInstance (Unknown Source)
com.google.firebase.remoteconfig.FirebaseRemoteConfig.getInstance (Unknown Source)
FirebaseRemoteConfig.getInstance is called during Application.onCreate and it worked fine on all previous versions.
Build:
implementation "com.google.firebase:firebase-config:15.0.0"
classpath 'com.google.gms:google-services:3.2.1'
Does anyone see it? Any solutions or workarounds?
P.S. I've sent bug report to firebase team via https://firebase.google.com/support/contact/bugs-features/
https://github.com/firebase/quickstart-android/issues/474
According to https://github.com/firebase/quickstart-android/issues/474 is't fixed with 15.0.2 update to Firebase RemoteConfig

How to fix this issue ?
Download google-services.json from Project Settings in the Firebase console. My mistake was downloading it from https://developers.google.com/mobile/add.
Changing google-services.json file didn't worked for me
later i found out
that i was using
implementation 'com.google.firebase:firebase-analytics:17.5.0'
implementation 'com.google.firebase:firebase-database:16.0.4'
instead of
implementation 'com.google.firebase:firebase-analytics-ktx:17.5.0'
implementation 'com.google.firebase:firebase-database-ktx:19.4.0'
mFirebaseDatabaseReference = database.getInstance().getReference("root-element in firebase");
When you call getReference you need to provide a URL. If your project is bound already in Firebase with the database you have created, use the root element of the data in Firebase as the parameter to getReference().
