I managed to get apple sign in working and create a userdoc on my firestore collection ('Users). However when I log out and sign in again with apple it overwrites the name "" ... Because it only logs the name the first time you log in with apple. How do I stop the name field to be overwritten everytime the same person signs out and in again?
case AuthorizationStatus.authorized:
try {
final res = await FirebaseAuth.instance.signInWithCredential(credential);
if (fixDisplayNameFromApple != null && res.user!.displayName == null) {
await res.user!.updateDisplayName(fixDisplayNameFromApple);
res.user!.reload();
}
FirebaseFirestore.instance.collection('Users').doc(res.user!.uid).set({
'name' : fixDisplayNameFromApple,
'email': res.user!.email,
'uid': res.user!.uid,
'image': 'https://merakiapp.be/wp-content/uploads/2022/06/appleUser.png',
}, SetOptions(merge: true));
return res.user;
} catch (e) {
print("error");
}
break;
I tried to check if the doc already exists so it doesn't create (overwrites) the original doc. But then it doesn't create a doc on firestore:
case AuthorizationStatus.authorized:
try {
final res = await FirebaseAuth.instance.signInWithCredential(credential);
if (fixDisplayNameFromApple != null && res.user!.displayName == null) {
await res.user!.updateDisplayName(fixDisplayNameFromApple);
res.user!.reload();
}
await FirebaseFirestore.instance
.collection("Users")
.doc(res.user!.uid)
.get()
.then((doc) {
if(doc.exists) {
return res.user;
} else {
FirebaseFirestore.instance.collection('Users').doc(res.user!.uid).set({
'name' : fixDisplayNameFromApple,
'email': res.user!.email,
'uid': res.user!.uid,
'image': 'https://merakiapp.be/wp-content/uploads/2022/06/appleUser.png',
}, SetOptions(merge: true));
return res.user;
}
});
} catch (e) {
print("error");
}
break;

You need to start by adding the lib
flutter pub add firebase_auth
then you need to make sure you installed firebase core and it's working from your app to firebase,
flutter pub add firebase_core
to init your firebase app, start by setting the options
class DefaultFirebaseOptions {
static FirebaseOptions get currentPlatform {
if (kIsWeb) {
return web;
}
switch (defaultTargetPlatform) {
case TargetPlatform.android:
return android;
case TargetPlatform.iOS:
return ios;
case TargetPlatform.macOS:
return macos;
case TargetPlatform.windows:
throw UnsupportedError(
'DefaultFirebaseOptions have not been configured for windows - '
'you can reconfigure this by running the FlutterFire CLI again.',
);
case TargetPlatform.linux:
throw UnsupportedError(
'DefaultFirebaseOptions have not been configured for linux - '
'you can reconfigure this by running the FlutterFire CLI again.',
);
default:
throw UnsupportedError(
'DefaultFirebaseOptions are not supported for this platform.',
);
}
}
static const FirebaseOptions web = FirebaseOptions(
apiKey: ,
appId: ,
messagingSenderId: ,
projectId: ,
authDomain: ,
storageBucket: ,
measurementId: ,
);
and the initialization of your app
switch (defaultTargetPlatform) {
case TargetPlatform.windows:
_app = await desktop.Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);
break;
default:
_app = await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform);
}
await Firebase.initializeApp();
and todo simple log in try
try {
final credential = await FirebaseAuth.instance.createUserWithEmailAndPassword(
email: emailAddress,
password: password,
);
} on FirebaseAuthException catch (e) {
if (e.code == 'weak-password') {
print('The password provided is too weak.');
} else if (e.code == 'email-already-in-use') {
print('The account already exists for that email.');
}
} catch (e) {
print(e);
}

I am following this guide to build my App. Then, I add a document listener to the "users" collection. Now the problem is even if I log out of the first account and log in to the second account, the stream is still reading the previous document if I manually change the document using the console.
Account _userInfo = Account(email: '', name: '', typeName: '', fcmToken: '', isDisable: false);
Account get userInfo => _userInfo;
StreamSubscription<DocumentSnapshot>? userListener;
Future<void> init() async {
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);
FirebaseAuth.instance.userChanges().listen((user) async {
if (user != null) {
print('User != null');
_loginState = ApplicationLoginState.loggedIn;
await setFcmToken();
listenToMyself();
} else {
print('User null');
userListener?.cancel();
_loginState = ApplicationLoginState.loggedOut;
}
notifyListeners();
});
void listenToMyself() {
print('Listening to: ${FirebaseAuth.instance.currentUser!.uid}');
userListener = usersCollection.doc(FirebaseAuth.instance.currentUser!.uid).snapshots().listen(
(event) {
print("current data: ${FirebaseAuth.instance.currentUser!.uid} ${event.data()}");
_userInfo = Account.fromJson(event.data() as Map<String, dynamic>);
notifyListeners();
},
onError: (error) => print("Listen failed: $error"),
);
}
Future<void> setFcmToken() async {
String? token = await FirebaseMessaging.instance.getToken();
_token = token;
await FirebaseFirestore.instance.collection('users').doc(FirebaseAuth.instance.currentUser!.uid).set({'fcmToken': token}, SetOptions(merge: true));
}
I want to store the URL of the image like this -
this is how i want to store url of the image in firestore
This is my current condition -
Currently it's showing the path of the image not the url
onPressed: () async {
if (imageFile == null) {
print("error");
} else {
try {
final ref = storage
.ref()
.child('user_profile_images')
.child(name + '.jpg');
ref.putFile(imageFile!);
url = await ref.getDownloadURL();
if (url != null) {
print(url);
}
} catch (e) {
print(e);
}
dynamic user = await auth.createUserWithEmailAndPassword(
email: email, password: password);
await FirebaseFirestore.instance
.collection('users')
.doc(name)
.set({
'email': email,
'name': name,
'profileurl': imageFile?.path,
'userid': auth.currentUser?.uid
}).then((value) {
try {
if (user != null) {
Navigator.pushNamed(context, '/dashboard');
}
} catch (e) {
print(e);
}
});
}
}),
I have a feeling the multiple try/catch blocks are getting in your way. In addition, it is never a good idea to mix then and await in a single block of code.
Combining those, try the following:
try {
final ref = storage
.ref()
.child('user_profile_images')
.child(name + '.jpg');
ref.putFile(imageFile!);
url = await ref.getDownloadURL();
if (url != null) {
print(url);
}
dynamic user = await auth.createUserWithEmailAndPassword(
email: email, password: password);
dynamic value = await FirebaseFirestore.instance
.collection('users')
.doc(name)
.set({
'email': email,
'name': name,
'profileurl': url // 👈
'userid': auth.currentUser?.uid
});
if (user != null) {
Navigator.pushNamed(context, '/dashboard');
}
} catch (e) {
print(e);
}
'profileurl': imageFile?.path, => 'profileurl': url?.toString(),
I am developing a flutter application which uses stripe for payments. I am using https://pub.dev/packages/flutter_stripe for this.
Everything is working fine but whenever I initiate payments I always get a webpage middleware (Screenshots attached). What am I doing wrong?
Here is my implementation in Flutter
Future<void> makePayment(String planName, String type) async {
Fluttertoast.showToast(msg: "initiating Payments, Please wait.");
ApiProvider provider = ApiProvider();
final tokenResponse = await provider
.getPaymentToken(PlanPayment(planName: planName, type: type));
if (tokenResponse != null) {`
var _service = locator<NavigationService>();
String secret = tokenResponse.clientSecret;
// make a get call from this url
Map<String, dynamic> paymentIntentData = Map();
await payment.Stripe.instance.initPaymentSheet(
paymentSheetParameters: payment.SetupPaymentSheetParameters(
merchantCountryCode: 'IN',
testEnv: true,
paymentIntentClientSecret: secret,
googlePay: true,
));
try {
// await Stripe.instance.handleCardAction(secret);
await payment.Stripe.instance.presentPaymentSheet().then((value) {});
await payment.Stripe.instance
.confirmPaymentSheetPayment()
.then((value) async {
// await _service.pushNamed(paymentStatus, args: {'isSuccess': true});
});
} catch (e) {
// await _service.pushNamed(paymentStatus, args: {'isSuccess': false});
print("Stripe error" + e.toString());
}
await provider
.confirmPayment(tokenResponse.transactionId)
.then((value) async {
await _service
.pushReplacementNamed(paymentStatus, args: {"isSuccess": value});
});
}
}
`
Maybe you have a webhook put in your account?
1)Provide valid Secret key
2)Provide valid Publisable key
3)Update flutterstripe pacakge
4)provide valid currency code to create stripe account country
ex :- stripe account create india to inr etc..
5)Right Way to implemet
- Main.dart to main method run app to implemet
ex :--
Stripe.publishableKey = "your publishable key ";
- create controller / method
code:-
Map<String, dynamic>? paymentIntentData;
Future<void> makePayment({amount}) async {
try {
paymentIntentData =
await createPaymentIntent(amount: amount, currency: 'INR');
if (paymentIntentData != null) {
await Stripe.instance.initPaymentSheet(
paymentSheetParameters: SetupPaymentSheetParameters(
// applePay: true,
googlePay: const PaymentSheetGooglePay(merchantCountryCode: 'INR'),
merchantDisplayName: "PGA",
customerId: paymentIntentData!['customer'],
paymentIntentClientSecret: paymentIntentData!['client_secret'],
customerEphemeralKeySecret: paymentIntentData!['ephemeralkey'],
));
}
displayPaymentSheet();
} catch (err) {
logger.e(err);
}
}
void displayPaymentSheet() async {
try {
await Stripe.instance.presentPaymentSheet();
Get.snackbar("PaymentInfo", "Payment Successfully");
} on Exception catch (e) {
if (e is StripeException) {
logger.e(e, "Error From Stripe");
} else {
logger.e(e, "Unforeseen error");
}
} catch (e) {
logger.e("exeption === $e");
}
}
var id = "";
createPaymentIntent({amount, currency}) async {
try {
Map<String, dynamic> body = {
'amount': calculateAmount(amount: amount),
'currency': currency,
'payment_method_types[]': 'card'
};
var response = await http.post(
Uri.parse('https://api.stripe.com/v1/payment_intents'),
headers: {
'Authorization':
'Bearer YourSecretKey',
'Content-Type': 'application/x-www-form-urlencoded'
},
body: body,
);
if (response.statusCode == 200) {
var decode = jsonDecode(response.body);
logger.e(decode);
id = decode['id'];
return decode;
}
} catch (e) {
logger.e(e, "error charging user");
}
}
calculateAmount({amount}) {
logger.e(amount.round());
final a = (int.parse(amount.toString())) * 100;
logger.e(a.toString());
update();
return a.toString();
}
6) How to Access Stripe payment :-
ex :- any button click
ontap : (){
makePayment(
amount: "200")
}
hi every one I'm trying making my app with flutter . it is contains a sign up page so I write the code and I'm retrieving an information from the firebase after I upload it .
the below code is the sign up code
UserModel? _userFromFirebaseUser(User userCredential) {
return userCredential != null
? UserModel(
id: userCredential.uid,
bannerImageUrl: '',
name: '',
email: '',
profileImageUrl: '')
: null;
}
Stream<UserModel?> get userCredential {
return auth
.authStateChanges()
.map((userCredential) => _userFromFirebaseUser(userCredential!));
}
Future SignUp(email, password) async {
var formdata = formstate.currentState;
if (formdata!.validate()) {
print("valid");
formdata.save();
try {
UserCredential userCredential =
(await auth.createUserWithEmailAndPassword(
email: myemail!, password: mypassword!));
FirebaseFirestore.instance
.collection('Users')
.doc(userCredential.user!.uid)
.set({'name': email, 'email': email});
_userFromFirebaseUser(userCredential.user);
return userCredential;
} on FirebaseAuthException catch (e) {
if (e.code == 'weak-password') {
Navigator.of(context).pop();
print('The password provided is too weak.');
} else if (e.code == 'email-already-in-use') {
Navigator.of(context).pop();
print('The account already exists for that email.');
}
} catch (e) {
print(e);
}
} else {}
}
and the red line appears on this line _userFromFirebaseUser(userCredential.user); as it is appears in the picture . please help me
userCredential.user is User? not User
change the method parameter
UserModel? _userFromFirebaseUser(User? userCredential) {
return ....
}
