flutter phone auth doens't work in my boss phone - firebase

Question

helllo
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
but my boss refused to it. 😫😫😫
here's my code
Future createUserWithPhone({String phoneNumber, BuildContext context}) async {
String phoneNumberWith82 = '+82 $phoneNumber';
await fAuth.verifyPhoneNumber(
phoneNumber: phoneNumberWith82,
timeout: Duration(seconds: 60),
verificationCompleted: (AuthCredential authCredential) async {
print('here verificationcompleted');
✅ not a big deal, verificationCompleted doesn't work don't know why
await fAuth
.signInWithCredential(authCredential)
.then((AuthResult result) {
Fluttertoast.showToast(
msg: "success",
backgroundColor: Colors.black26,
textColor: Colors.white,
);
}).catchError((e) {
print('Error Occurs ⭐3');
return "error";
});
},
verificationFailed: (AuthException exception) {
Fluttertoast.showToast(
msg: 'too many request',
toastLength: Toast.LENGTH_LONG,
gravity: ToastGravity.BOTTOM,
timeInSecForIosWeb: 1,
backgroundColor: Colors.red,
textColor: Colors.white,
fontSize: 16.0);
return "error";
},
codeSent: (String verificationId, [int forceResendingToken]) async {
final _codeController = TextEditingController();
await showDialog(
context: context,
barrierDismissible: false,
builder: (context) => AlertDialog(
title: Text("write auth 6digit"),
content: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
TextField(
controller: _codeController,
keyboardType: TextInputType.number,
),
],
),
actions: <Widget>[
FlatButton(
child: Text("verify"),
textColor: Constants.kPrimaryOrange,
// color: Constants.kPrimaryOrange,
onPressed: () async {
var _credential = PhoneAuthProvider.getCredential(
verificationId: verificationId,
smsCode: _codeController.text.trim());
✅ Error Occurs HERE ✅✅✅✅✅✅✅✅✅✅✅✅✅✅✅✅✅✅✅✅
await fAuth
.signInWithCredential(_credential)
.then((AuthResult result) async {
var snapshot = await Firestore.instance
.collection('users')
.where('pid', isEqualTo: result.user.phoneNumber)
.getDocuments();
/// id doesn't exist.
if (snapshot.documents.length == 0) {
await Firestore.instance
.collection('users')
.document(result.user.uid)
.setData({
'uid': result.user.uid,
'pid': result.user.phoneNumber,
'name': randomName,
'createdAt': DateTime.now(),
'storeName': '',
});
Fluttertoast.showToast(
msg: "33",
backgroundColor: Colors.black26,
textColor: Colors.white,
);
} else {
Fluttertoast.showToast(
msg: " id exists",
backgroundColor: Colors.black26,
textColor: Colors.white,
);
}
setUser(result.user);
Navigator.pushNamedAndRemoveUntil(
context, SplashScreen.id, (route) => false,
arguments: result.user);
✅ catch }).catchError((e) {
Fluttertoast.showToast(
msg: e.toString(),
toastLength: Toast.LENGTH_LONG,
gravity: ToastGravity.BOTTOM,
timeInSecForIosWeb: 1,
backgroundColor: Colors.red,
textColor: Colors.white,
fontSize: 16.0);
Navigator.push(
context,
MaterialPageRoute(
builder: (context) =>
ErrorReading(errorMsg: e.toString())),
);
// Navigator.pop(context);
return "error";
});
},
),
FlatButton(
child: Text("close"),
textColor: Constants.kPrimaryOrange,
// color: Constants.kPrimaryOrange,
onPressed: () {
print('Error Occurs ⭐');
Navigator.pop(context);
},
)
],
),
);
},
codeAutoRetrievalTimeout: (String verificationId) {
verificationId = verificationId;
});
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

I tryed firebase_auth ^18 with core ^5 but many place to change recent code so I trying to figuring out with these versions

Answer 1

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.
