I started getting below error with Firebase Phone Authentication in my flutter app. What does error code 17499 mean? I couldn't get any info on this. Any hints to fix this? Thanks

This worked from after migrating to Dart only FlutterFire initialisation method.
It stopped working with manual initialisation using google-services.json.

I am pretty sure your issue is calling .uid on a user in your else block when the user is null, which throws an error. You should make sure that the user class is initialized or something similar atleast.

I'm trying to make phone auth with flutter
I managed to implement but doens't work in my boss phone (android)
in my phone it works.
that's why I'm almost crazy
I wanna connect boss phone with cable debug mode

await fAuth.verifyPhoneNumber(

I don't know cause of this problem , so i cannot fix it.
I used to toast to find error point.
then i found it ✅ look at this emoji
anybody?
firebase_auth: ^0.16.1
firebase_core: ^0.4.0
cloud_firestore: ^0.13.0
firebase_storage: ^3.1.6
I tryed firebase_auth ^18 with core ^5 but many place to change recent code so I trying to figuring out with these versions
Follow the steps as mentioned here.
You need to add both the SHA-1 Fingerprint and enable the Device Check API for Phone Auth to work in Android.
If you need a code sample for Phone Auth to work in
firebase_auth ^18 with core ^5, do let me know will edit this answer.
I'm working on a signup screen for my app. I implemented firebase and can authenticate user and save some user info into firebase database succesfully. I started to check if userName field is empty or not. But firebase sometimes can not catch exception about bad formatted email address. It works for password (min 6 char) everytime but sometimes work for email. I can't find any solution. Here is my code. Is there anybody who have an idea?
onPressed: () async {
if (validateName(userName) && validateEmail(email)) {
setState(() {
showSpinner = true;
});
try {
final newUser =
await _auth.createUserWithEmailAndPassword(
email: email, password: password);
if (newUser != null) {
//get name and update user profile
UserUpdateInfo userUpdateInfo = UserUpdateInfo();
userUpdateInfo.displayName = userName;
FirebaseUser user = await _auth.currentUser();
await user.updateProfile(userUpdateInfo);
await user.reload();
Navigator.pushNamed(context, NavigationScreen.id);
}
setState(() {
showSpinner = false;
});
} on PlatformException catch (e) {
setState(() {
showSpinner = false;
});
Fluttertoast.showToast(
msg: e.message,
toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 3,
backgroundColor: Colors.white,
textColor: Colors.red,
fontSize: 18.0,
);
}
} else {
Fluttertoast.showToast(
msg: 'You must ente all information',
toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 3,
backgroundColor: Colors.white,
textColor: Colors.red,
fontSize: 18.0,
);
}
},
//name TextField validation
bool validateName(String name) {
if (name != null && name.length > 2) {
return true;
} else {
return false;
}
}
//email TextField validation
bool validateEmail(String email) {
if (email != null) {
return true;
} else {
return false;
}
}
createUserWithEmailAndPassword returns a Future<AuthResult>, to catch the error you can do the following:
final newUser = await _auth.createUserWithEmailAndPassword(email: email, password: password).catchError((err) {
showDialog(
context: context,
builder: (BuildContext context) {
return AlertDialog(
title: Text("Error"),
content: Text(err.message),
actions: [
FlatButton(
child: Text("Ok"),
onPressed: () {
Navigator.of(context).pop();
},
)
],
);
});
Using catchError, it will handles errors emitted by this Future, and then showDialog will display a dialog with the error.
I want to allow users to register an account on my app using flutter with email/password, and then send code to the phone. So when user enters their data to Sign up, it should register them with their email and then use their phone to the verity code. Also the user can't complete the registration and go to the Home page Without checking the entered code.
But in my code it's not working what i want do it.

dynamic ruselt= await _auth.regsiterwithemail(_emailcontroller.text,_passwordcontroller.text);

});
}

I am trying to integrate authentication on Flutter using firebase_auth.
However, whenever I call the verifyPhoneNumber("+256XXXXXXXXXX") I get the error message A network error (such as timeout, interrupted connection or unreachable host) has occurred., that is from the PhoneVerificationFailed callback. An for that reason cannot get the SMS.
I have tried;
Adding network permissions as seen below to my file (my internet connection works, as I am able to Google via the emulator)
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
Checking the validity of my API keys
I am totally confused as to why Flutter is unable to communicate with firebase. I have two questions.
How can I eliminate this error?
What other cases might cause this error besides a lacking internet connection?
My implimentatioin is as below;
import 'package:firebase_auth/firebase_auth.dart';
FirebaseAuth auth = FirebaseAuth.instance;
var message;
// fire this when Phone verification is completed
final PhoneVerificationCompleted verificationCompleted =
(AuthCredential phoneAuthCredential) {
auth.signInWithCredential(phoneAuthCredential);
message = 'Received phone auth credential: $phoneAuthCredential';
print(message);
};
// fire this when Phone verification fails
final PhoneVerificationFailed verificationFailed =
(AuthException authException) {
message =
'Phone verification failed. Code: ${authException.code}. Message: ${authException.message}';
print(message);
};
// fire this when SMS code is sent is sent.
final PhoneCodeSent codeSent =
(String verificationId, [int forceResendingToken]) async {
verificationId = verificationId;
print('Sent verification code');
};
// fire this when smsCode expires
final PhoneCodeAutoRetrievalTimeout codeAutoRetrievalTimeout =
(String verificationId) {
verificationId = verificationId;
print('Auto retrival time-out');
};
// verify phone number
verifyPhoneNumber(String phoneNumber) {
auth.verifyPhoneNumber(
phoneNumber: phoneNumber,
timeout: const Duration(seconds: 30),
verificationCompleted: verificationCompleted,
verificationFailed: verificationFailed,
codeSent: codeSent,
codeAutoRetrievalTimeout: codeAutoRetrievalTimeout);
print('Verification Initiated');
}
// sign in with phone.
signInWithPhoneNumber(String smsCode, String verificationId) async {
final AuthCredential credential = PhoneAuthProvider.getCredential(
verificationId: verificationId,
smsCode: smsCode,
);
final FirebaseUser user = (await auth.signInWithCredential(credential)).user;
final FirebaseUser currentUser = await auth.currentUser();
assert(user.uid == currentUser.uid);
if (user != null) {
message = 'Successfully signed in, uid: ' + user.uid;
} else {
message = 'Sign in failed';
}
}
In my case I solved allowing Outgoing Connections on the Xcode's Runner.xcworkspace
In my case, my VPN was causing the problem. Disabling the VPN and testing it again solved the error. I hope it helps.
if you are trying this out in a simulator, then this error may pop up as the internet of your simulator is not connected. To solve this you can run your app on a physical device and it will work!
I am late to the party but I found another solution.
If using an android emulator, disabling the Android Studio HTTP proxy settings can restore the network connection.
Normally when the emulator is doing a lot of work on the thread, it tends to misbehave, such a losing internet connectivity even if your PC is well connected.
My suggestion(Which worked for me) is you kill the emulator, and go to Android Studio AVD Manager and Wipe Data for that Emulator, then restart the Emulator, it worked for me.
Kindly find below the image screenshot

This network error has stopped me too and I have been seeking an answer ... After reading MaximeBeasse's response above and trying it out, I found that it worked : ) Authentication now works! Finally I can move on!
Many thanks #MaximeBeasse -- salute his answer please
