Creating and maintaining this package takes a lot of time. If you like the result, please consider to ❤️ sponsor. With your support, I will be able to further improve and support this project. Also, check out my other dart packages at pub.dev.
Many thanks to Tim Whiting for his support.
Hi,
i use your plug in and i found some problem how to upload file using putData like image and etc.
Thanks you,
QueryFilter does not yet implement the startAt and endAt
Hi,
I am attempting to re-authenticate a user using the reauthenticateWithCredential(AuthCredential credential) method. While the method operates correctly, it fails in the method:

Hi,
I have see that the credential persistence is not supported for now.
But, is there a way to implement it by ourself, or an alternative?
By example, if at some point we receive a token and later we can authenticate with this token (by example)?
In such case, we can store the token locally (and not the user/password by example)

Hello,
Do you plan to implement some missing functionnalities of Firebase Auth?
I'm especially in need of these two:
FirebaseAuth.setLanguageCode
User.reauthenticateWithCredential
Thanks a lot for your amazing work!
After writing more than 2 entries into the database. Trying to do so again after more than 70 seconds - just nothing happens.
It is necessary to delete the FirebaseApp and reinitilize it again to be able to write.
What can be the problem here?
Tested with:
Dart SDK version: 2.19.4 (stable)
firebase_dart: ^1.0.11 & firebase_dart: ^1.1.0-dev.10
Example:
const configMB = FirebaseOptions(
apiKey: 'XXXX-XXXXXX-VpFyS3bbNo',
authDomain: 'XXXX-XXX.firebaseapp.com',
projectId: 'XXX-XXX',
messagingSenderId: 'XXXXXXXX',
databaseURL: 'https://XXX-XXX.firebaseio.com',
storageBucket: 'XXX-XXXX',
appId: '1:XXXX:ios:442813749dccf0d1');
class TKDatabase {
static Future<void> configureDatabases() async {
FirebaseDart.setup();
await Firebase.initializeApp(name: "mb", options: configMB);
}
static Future<void> reinitialize() async {
await Firebase.app("mb").delete();
await Firebase.initializeApp(name: "mb", options: configMB);
}
static FirebaseDatabase mb() => FirebaseDatabase(app: Firebase.app("mb"));
}
void main(List<String> arguments) async {
await TKDatabase.configureDatabases();
log('✅ Firebase Database connected.');
// FAILING TEST
TKDatabase.mb().reference().child('test/a').set({'test': 'test123'});
TKDatabase.mb().reference().child('test/a').set({'test': 'test1234'});
Timer.periodic(Duration(seconds: 70), (_) async {
log('The following write is just IGNORED');
TKDatabase.mb().reference().child('appconfig/test').set('test');
});
// SUCCESSFUL TEST
Timer.periodic(Duration(seconds: 70), (_) async {
log('The following workaround works...');
await TKDatabase.reinitialize();
TKDatabase.mb().reference().child('appconfig/test').set('test');
});
}
I really like your work.
Do you have any plan to support firestore in the future?
In #21 (comment) you mentioned to be looking for funding. I guess if merging with flutterfire_desktop would be an option, funding from Google, Invertase, Canonical or others would be easier to get. What do you think?
Because Flutter 3.22.0 depends on intl: ^0.19.0 it is not possible to use firebase_dart which depend on intl: ^0.18.0
Could you please upgrade it?
Currently only works on server as it depends on the WebSocket class in dart:io.
Create a Transport that works with the WebSocket class in dart:html.
I'm calling _database.setPersistenceEnabled(true) and also called FirebaseDart.setup(storagePath: 'E:/firebasedart');
but whenever i'm calling ref() but this is not working

Is there a way to auth using service account json file like node.js sdk does:
var admin = require('firebase-admin');
var serviceAccount = require('path/to/serviceAccountKey.json');
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: 'https://<DATABASE_NAME>.firebaseio.com'
});I tried auth with secret key (the same way you do in auth test but added admin flag) and it worked, but I was not able to read data that has read rule set to false.
In the official firebase implementations, you can store Json lists (internally they are just recognized as Maps that have sequential numbering starting from zero). When attempting to do that with this library, I am able to save lists, but when reading them back, they end up as maps. This causes problems with json serialization libraries.
Any recommended way to approach this? Making everything maps is not the solution I'm looking for.
In example:
var ref = new Firebase("https://n6ufdauwqsdfmp.firebaseio-demo.com/");
ref.child("test").onValue.listen((e) {
print(e.snapshot.val);
});
If there's no internet or url is invalid or child does not exists - how to catch error? Without it, library is useless. Currently, if no internet connection, listen is never executed, but I am unable to catch there was some error.
Hi,
I'm using this for an app that will predominantly run on a desktop (not mobile).
My files are stored in the default bucket, in a folder named audio at the root.
I can get all the files from that folder using a function like:
Future<ListResult> listAll() async {
var app = await Firebase.initializeApp(
options: FirebaseOptions.fromMap(json.decode(File('firebase-config.json').readAsStringSync()))
);
var storage = FirebaseStorage.instanceFor(app: app);
var results = await storage.ref("audio").listAll();
return results;
}
Note: Also tried with await.storage.ref().child('audio').listAll();
But when I loop the returning files, each one appears with the root folder "duplicated".
For example, the fullPath property of each Reference is audio/audio/file.mp3 instead of audio/file.mp3.
This results in a "file not found" when i'm trying to get a download url. The url comes as: gs://bucket-name.appspot.com/audio/audio/file.mp3 - with double audio/audio.
Update: I can get the right reference by doing something convoluted like: Reference? realItem = item.parent?.parent?.child(item.name); when looping the results, but that feels a bit off.
Any idea what I'm doing wrong?
Many thanks!
you are still depending on ^0.13.0, and it's restricting alot of other packages
I've been seeing an issue that pops up every once in a while. A get() on a piece of the database just waits forever and times out. All of the following get() calls do the same. We think that it might have something to do with re-authentication with a service account using the firebase_admin package

Hello,
Everything work fine on debug mode, but when I build my app on release mode with the command "flutter build windows" and then run the .exe on the same computer, the app is stucked on a white screen.
It doesn't happen when I comment this line:
await Firebase.initializeApp(
options: FirebaseOptions.fromMap(json
.decode(File('example/firebase-config.json').readAsStringSync())));
I found a Stackoverflow issue with a similar problem: https://stackoverflow.com/a/69221938
The reason for not finding that in release mode can be one of the following,
You are using some dll (package that depends on a dll) that is available on a specific path in your system, but when you are release the app that (absolute) path is not valid anymore.
Thank you for you help and for this amazing package!
Apparently this library handles the "Realtime Database", as opposed to the "Firestore Database".
When I try to instantiate the storage with a custom bucket a object not found error occurs when trying to upload or receive metadata, etc.
var storage = FirebaseStorage.instanceFor(
app: cloudStorageApp,
bucket: 'gs://...'
);
Error message:
flutter: [storage/object-not-found] Object 'path/to/object' does not exist.
I double checked that there is a file in the expected location in firebase console.
When I use the default bucket it works perfectly fine.

firebase_dart also suffers from it.
Since jose has been already published by you (appsup-dart/jose#53) could you please also upgrade firebase_dart?
We'd also love to see intl and http packages upgraded.
Thank you in advance

Does this package support offline storage for the realtime db? I set the desired persistence path, but it does not seem any files are written there, and if I try to get some data when I got no internet connection, the code is stock within the get method.
If this is not supported, what would be the preferred way to store the data and sync when going online again?
Thanks for your help!
Hi, I'm New to this.
may I know how to push and fetch data To & From Firebase Database.
i tried but it doesn't works
var ref = db.reference().child('test');
await ref.set({
'Value': {'One': 1, 'Two': 2, 'Three': 3}
});
await ref.set({'Box': json});
await ref.update({"Box": json});
Thanks For Your Contribution.
It would be good if the makers of this were to do a video or something.
The sample is not working.
I find this not usable.
I can get firedart to work, but I guess this package has better support and is a newer and current fork.
On your package...
I'm able to setup and initialize but cannot do much else. Errors flow on sign in and when i comment out the user stuff errors flow when I ask for storage.
I assumed the file to initialize was a google-services.json, but that did not load from assets, so I manually added my options locally in code. That worked.. but cannot do anything else.
I should note that I'm using flutter 2.10.5 because of another project requires a downgrade.
just trying the library and I can't even get authenticated lol.

Hi thank you for your package, I just wander if you going to firestore support in this package any time soon,
Thank you.
Hello and many thanks for this awesome package. I was trying to create to validate tokens sent from the client to my server. Using the package firebase_auth_admin_verify successfully verifies tokens generated from firebase_core and firebase_auth., but when I try with this package, it says No kid available.
Could you please assist me with pointing out this issue or if the problem is in the firebase_auth_admin_verify package?
import 'package:firebase_auth_admin_verify/firebase_auth_admin_verify.dart';
import 'package:firebase_dart/firebase_dart.dart';
import 'package:firebase_dart/implementation/testing.dart';
import 'package:test/test.dart';
void main() {
test('verifies token successfully', () async {
final token = await _getTestToken();
final jwt = await verifyFirebaseToken(
token,
serviceFilePath: 'service-account.json',
projectId: 'my_project',
);
});
}
Future<String> _getTestToken() async {
await FirebaseTesting.setup();
final app = await Firebase.initializeApp(
options: FirebaseOptions(
appId: 'my_app_id',
apiKey: 'apiKey',
projectId: 'my_project',
messagingSenderId: 'ignore',
authDomain: 'my_project.firebaseapp.com'),
);
var backend = FirebaseTesting.getBackend(app.options);
final email = '[email protected]';
final password = 'password';
final user = await backend.authBackend.createUser(
email: email,
password: password,
);
// final token = await backend.authBackend.generateIdToken(uid: uid, providerId: providerId)
var auth = FirebaseAuth.instanceFor(app: app);
final cred = await auth.signInWithEmailAndPassword(
email: email,
password: password,
);
return await backend.authBackend.generateIdToken(
uid: cred.user!.uid,
providerId: cred.additionalUserInfo!.providerId!,
);
}
I am trying to implement this library into my app and found something I don't understand:
When I sign in with email and password, I get back the UserCredentials.
Now the official Firebase auth package does not need any additional code to stay signed in. If I reload the app, I am still signed in.
When I use this package and reload after I signed in, it seems I am not anymore. Do I have to store something like a token after I sign in?
putData() function when called on storage reference along by passing settablemetadata uploads the data but with no metadata.
Here is the code
UploadTask task = storage
.refFromURL('location_url')
.child('${map['id']}.mp4')
.putData(uint8List, metadata);
Also no errors are being generated as I am also checking it afterwards
task.snapshotEvents.listen((event) {
if (event.state == TaskState.error) {
print('Some serious error is coming');
} else {
print('It works');
}
});
It works gets printed.
The code works on a flutter app but not inside the script.
Because Flutter 3.10.0 depends on intl: ^0.18.0 it is not possible to use firebase_dart which depend on intl: ^0.17.0
Could you please upgrade it?
Sometimes i get these errors while uploading data to firebase storage. However when i put UploadTask in try catch block, catch part doesnt work and also when i listen uploadtask onError part doesnt work too. For example it doesnt print "upload get err1 or err2".
try {
uploadTask = ref.putData(File(file.filePath).readAsBytesSync());
await uploadTask.snapshotEvents.listen((snapshot) {
uploadingValue =
((snapshot.bytesTransferred / snapshot.totalBytes) * 100).toInt() /
100;
print('Progress: %${uploadingValue * 100}');
}, onDone: () async {
print("UPLOAD DONE!!!");
print("uploadFail:$cloudFail");
if (!cloudFail) {
setState(() {
uploaded = true;
});
await triggerStorageFiles();
saveDb();
}
}, onError: (e) {
print("upload get err1:$e");
cancellUpload();
cloudFail = true;
saveDb();
});
} catch (e) {
print("upload get err2:$e");
}
By the way its happening while connected wifi. I dont get this err when i connected with cable.
Edit:
same error
Unhandled Exception: SocketException: OS Error: Operation timed out, errno = 60, address = firebasestorage.googleapis.com, port = 51294
its happening while uploading big file or 20-30 small files. So i think its becoming timed out with wifi connection. How can i fix it :(
