This is a most likely a transient condition and may be corrected by retrying with a backoff

Question

I'm using firebase in my project and i got some issues mentioned below -

[cloud_firestore/unavailable] The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.

I'm using firebase lib version :

 firebase_auth: ^0.18.0+1
 google_sign_in: ^4.5.3
 cloud_firestore: ^0.14.3
 firebase_core: ^0.5.2
 firebase_messaging: ^7.0.3
 firebase_storage: ^4.0.0

flutter run --verbose - result :

Welcome to Stack Overflow, Sonu Saini! I recommend you to read "How do I ask a good question" and you should provide a minimal reproducible example. With that, some user could help you better. – Crownwork

Any updates i am also getting this issue in android and i am using mac – Clabber

I'm getting this as well... – Copolymerize

Have the same issue on Mac with iOS Emulator - doesn't matter if I use the firebase emulator or try to connect to live firestore (cloud). – Ostyak

Answer 1

This answer might be quite late, but whoever visits here for this error, I have few things to tell,

1. If you are operating with your features, make sure it is connected to internet for firebase operations.

2. If your module works with firebase with offline support, make sure you have the collection and all documents which are related to your module cached first. That way you can avoid this error. If offline mode included, clearly you might have enabled the persistance in firebase, if not then please go through this link.

3. If working offline and above is not working, make sure to check and verify the presence of collection/document in firebase.

4. You can also utilise the alternatives such as try...catch... and play around for fixing.

5. There might be a chance of glitch from server's end for which we cannot do much.

In majority of the case there might be some code issue from our end, You can verify it by checking other firebase calls to confirm whether it is from server side fault or not.

Answer 2

For me, the issue is happening in the real device, in which the internet connection is low or no When a strong Wifi/Mobile network is there, it's not showing.

Also I wrap all my firestore-functions in a service.dart file with try & catch blocks, so this is not a major problem for me, but anyone who think this as a major issue can try out the below codes.

Note: This is not useful for everyone, may be for someone. Plugins:

Answer 3

One can try this com.google.gms:google-services:4.3.3 Please focus on version

As it’s currently written, your answer is unclear. Please edit to add additional details that will help others understand how this addresses the question asked. You can find more information on how to write good answers in the help center. – Pemberton

Answer 4

Add the latest google-services dependency (which is 4.3.3 as of now) to your project-level build.gradle like so:

buildscript {
    ...
    dependencies {
        ...
        // START: FlutterFire Configuration
        classpath 'com.google.gms:google-services:4.3.3'
        // END: FlutterFire Configuration
        ...
    }
    ...
}
...

Answer 5

I got this error and doing the backoff approach.

Using retry package.

Sample of retrying un any exception case:

  @override
  Future<DocumentReference<T>?> add(T data, {String? documentId}) async {
    const retryOp = RetryOptions(maxAttempts: 2);
    final response = await retryOp.retry(
      () async {
        var collection = getCollectionReference().withConverter(
          fromFirestore: fromFirestore,
          toFirestore: toFirestore,
        );

        if (documentId != null) {
          var document = collection.doc(documentId);
          await document.set(data);
          return document;
        }
        return collection.add(data);
      },
      retryIf: (e) => true, // retry any case
    );

    return response;
  }

Answer 6

On emulator: wipe out emulator data then load the app. On phone: turn off the data then restart your phone then turn on the data and load the app

I solved the issue with this

Sunlight

I am facing this problem in 5 different devices, how can I fix it by restarting my device – Krasnoff

@Hamza Ali have you tried my solution? if not work then check the internet connection on your devices. – Sunlight

It is not working – Contumacy

Answer 7

If anyone getting this error on a real device then at least try this solution.

Make sure you have enabled internet permission in main AndroidManifest.xml file. .

Try setting the minifyEnabled and shirnkResources flags to false in the android/app/build.gradle.

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.debug
        shrinkResources false
        minifyEnabled false
    }
}

This worked for me.

I took help from the below link and you can find other solution for this topic on this page too.

Answer 8

In my case , the problem was that i was trying to use offline persistence without caching the data first . So , make sure you have fetched first before trying to access cached data.

Outrigger

Your solution worked for me too. I was trying to use offline persistence without fetching the data first. Thanks for the tip! – Estriol

Answer 9

While there are many great answers, for me specifically it happened when I accidentally forgot to make the app connect to Firebase instead of the Firebase Emulator.

Here is an example for connecting to a local firebase server:

FirebaseFirestore.instance.settings = const Settings(
  host: '10.0.2.2:8080',
  sslEnabled: false,
);

It may cause the following error if you don't have a local firebase emulator running.

[cloud_firestore/unavailable] The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.

If you wish to connect to the remote firebase server, just remove or comment the code that makes it connect to the local server (like the code above)

Answer 10

await FirebaseFirestore.instance.disableNetwork();
await FirebaseFirestore.instance.enableNetwork();

add this before you call .get()

It didn't work for me. – Beirut

I tried this but it didn't work. – Beirut

This is not the solution – Ocana

Answer 11

It works for me after wiping my emulator data.
