(Flutter) User is always getting null and unable to create user in realtime database
Future validateform() async {
FormState? formState = _formKey.currentState;
if(formState!.validate()) {
formState.reset();
User? user = firebaseAuth.currentUser;
// String? useruid = user!.uid;
print(user);
if(user == null ) {
print(_emailTextController.text);
print(_nameTextController.text);
print('UserID: '+'{$user}');
print(gender);
firebaseAuth
.createUserWithEmailAndPassword(
email: _emailTextController.text,
password: _passwordTextController.text)
.then((user) => {
_userServices.createUser(
{
"username": _nameTextController.text,
"email": _emailTextController.text,
// "userId": useruid,
"userId": user.user!.uid,
// "userId": "5as564d65as4d65as4d65as4d64",
"gender": gender,
})
}).catchError((err) => {print(err.toString())});
// });
print(user);
if (user!=null) {
Navigator.pushReplacement(
context,
MaterialPageRoute(builder: (context) => HomePage()),
);
}
}
}
}
I was expecting it to creaete in REALTIME DATABASE as user details, but user is always null.

I am trying to have access to notificationId once it gets created however the delete function deletes all the documents under this collection ('user-notifications').
Do you know what I need to change so I can remove only one document rather than all documents in this collection?
Future<String> likeAnnouncementNotification(String announcementId,
String imageUrl, String ownerUid, String uid, List liked) async {
String notificationid = const Uuid().v1();
String res = "Some error occurred";
try {
if (liked.contains(uid)) {
FirebaseFirestore.instance
.collection('notifications')
.doc(ownerUid)
.collection('user-notifications')
.where("uid", isEqualTo: FirebaseAuth.instance.currentUser?.uid)
.get()
.then((value) {
value.docs.forEach((document) {
document.reference.delete();
});
});
} else {
FirebaseFirestore.instance
.collection('notifications')
.doc(ownerUid)
.collection('user-notifications')
.doc(notificationid)
.set(
{
'imageUrl': imageUrl,
'announcementId': announcementId,
'notificationid': notificationid,
'timestamp': DateTime.now(),
'type': 0,
'uid': uid
},
);
}
res = 'success';
} catch (err) {
res = err.toString();
}
return res;
}
the only thing i see that you need to specify what notification document you went to delete add it like parameter when you call likeAnnouncementNotification function
Future<String> likeAnnouncementNotification(
String announcementId,
String imageUrl,
String ownerUid,
String uid,
List liked,
) async {
String notificationid = const Uuid().v1();
String res = "Some error occurred";
try {
if (liked.contains(uid)) {
FirebaseFirestore.instance
.collection('notifications')
.doc(ownerUid)
.collection('user-notifications')
.where("uid", isEqualTo: FirebaseAuth.instance.currentUser?.uid)
.get()
.then((value) {
value.docs.forEach((notification) {
FirebaseFirestore.instance
.collection('notifications')
.doc(ownerUid)
.collection('user-notifications')
.doc(notification.id) // this is the problem you need to specify what notification document you went to delete.
.delete();
});
});
} else {
FirebaseFirestore.instance
.collection('notifications')
.doc(ownerUid)
.collection('user-notifications')
.doc(notificationid)
.set(
{
'imageUrl': imageUrl,
'announcementId': announcementId,
'notificationid': notificationid,
'timestamp': DateTime.now(),
'type': 0,
'uid': uid
},
);
}
res = 'success';
} catch (err) {
res = err.toString();
}
return res;

I am unable to store data in cloud firestore. Authentication is all correct but the data is not going in cloud firestore and because of that login also not working because cloud firestore is pre-req to login function
That's my AuthContoller function
storeUserData({name, password, email}) async {
DocumentReference store = firestore
.collection("users")
.doc(FirebaseAuth.instance.currentUser!.uid);
store.set(
{'name': name, 'password': password, 'email': email, 'imageUrl': ''});
}
and that's my signup button code
try {
await controller
.signupMethod(
context: context,
email: emailController.text,
password: passwordController.text,
)
.then((value) {
** return controller
.storeUserData(
email: emailController.text,
name: nameController.text,
password: passwordController.text)
.then((value) {
VxToast.show(context,
msg: 'Account Created Sucessfully');
Get.offAll(LoginScreen());
}); **
});
} catch (e) {
FirebaseAuth.instance.signOut();
VxToast.show(context, msg: e.toString());
}
try this
storeUserData({name, password, email}) async {
final _firestore = FirebaseFirestore.instance;
await _firestore.collection("users")

The database is structured like this
Your code says:
FirebaseStorage.instance
.ref()
.child('profile')
.getDownloadURL()
But in the screenshot, the file is called profile.png. The path must match completely and exactly, so:
FirebaseStorage.instance
.ref()
.child('profile.png')
.getDownloadURL()
I'm trying to use flutter_stripe for a stripe connect account, But I always get the
same error: The client_secret provided doesn't match the client_secret associated with the PaymentIntend.
I've completed all steps according to flutter_stripe but I still face this error.
Below is my code Please check this and help me.
inde.js
const functions = require("firebase-functions");
const stripe = require("stripe")("secret_key");
exports.stripePaymentIntentRequest = functions.https.onRequest(async (req, res) => {

const customerList = await stripe.customers.list({
email: req.body.email,
limit: 1
});
//Checks the if the customer exists, if not creates a new customer
if (customerList.data.length !== 0) {
customerId = customerList.data[0].id;
}
else {
const customer = await stripe.customers.create({
email: req.body.email
});
customerId = customer.data.id;
}
//Creates a temporary secret key linked with the customer
const ephemeralKey = await stripe.ephemeralKeys.create(

customer: customerId,
})
res.status(200).send({
clientSecret: paymentIntent.client_secret,
paymentIntent: paymentIntent,
ephemeralKey: ephemeralKey.secret,
customer: customerId,
success: true,
})
} catch (error) {
res.status(404).send({ success: false, error: error.message })

The following code is from a previous Stripe evaluation stage. But it worked. Slim it down to your needs.
Remember to publish your secret key to the server, so the server can talk to Stripe.
code.dart

Here I am doing login when I am logged in successfully it will store all the info in SQFLite database.
here is my login response where I don't know how to store string array and JSON in flutter SQFlite. I need to store all this response info in SQFLite.
Can anyone helps me to create a table based on this response?

Here is a one way of doing it:
import 'dart:io';
import 'package:path/path.dart';

import 'package:path_provider/path_provider.dart';
import 'package:utility_demos/user_management/user.dart';
import 'package:sqflite/sqflite.dart';
class DatabaseHelper {
static final DatabaseHelper _instance = new DatabaseHelper.internal();
factory DatabaseHelper() => _instance;
static Database _db;
Future<Database> get db async {
if (_db != null) {
return _db;
}
_db = await initDb();
return _db;
}
DatabaseHelper.internal();
// create database
initDb() async {
Directory documentDirectory = await getApplicationDocumentsDirectory();
String path = join(documentDirectory.path, "main.db");
var ourDb = await openDatabase(path, version: 1, onCreate: _onCreate);
return ourDb;
}
// create tables
void _onCreate(Database db, int version) async {
await db.execute(
"CREATE TABLE User(uid INTEGER AUTO INCREMENT PRIMARY KEY, token TEXT, user TEXT)");
// note that Im inserting password as plain text. When you implement please store it as a hash for security purposes.
}
// insert user to db when login
Future<int> saveUser(User user) async {
Database dbClient = await db;
int res = await dbClient.insert("User", user.toMap());
return res;
}
// retrieve user from db
Future<User> getUser() async {
var dbClient = await db;
List<Map> list = await dbClient.rawQuery('SELECT * FROM User');
if (list.isNotEmpty) {
return User.fromJson(list.elementAt(0));
}
return null;
}
//delete use when logout
Future<int> deleteUser() async {
var dbClient = await db;
int res = await dbClient.delete("User");
return res;
}
// check if the user logged in when app launch or any other place
Future<bool> isLoggedIn() async {
var dbClient = await db;
var res = await dbClient.query("User");
return res.length > 0 ? true : false;
}
}
Here is the User model class:
class User {
final String user;
final String token;
User(this.user, this.token);
// here because of user object is too long Im storing it as string
// and that is actually not a good way to do this because of when you want to
// fetch user and handle information it will be very hard to do those and also when testing
// please map other properties in your json to model and that's the best way.
User.fromJson(dynamic obj)
: this.user = obj['user'].toString(),
this.token = obj['token'];
String get getUser => user;
String get getToken => token;
Map<String, dynamic> toMap() => {'user': user, 'token': token};
}
Here I have created a simple widget tree to show you. How to store retrieved json object properties. Please note that I'm storing json user object as String because of its pretty long. Its better to create your model for all variables and map them. See comment in User class.
