I am new to Flutter/Firebase/Firestore etc.. so I am struggling a bit. I want to grab the data from the documents in my ‘users’ collection in Firestore and display it in my account information page. I have spent hours messing around with this and I am stuck. If anybody could help me out that would be wonderful!
Here are some samples of what my code, app, and firestore look like.
Code:
signup.dart – this is the page that creates the doc in Firebase on signup
class SignUp extends StatefulWidget {
const SignUp({Key? key}) : super(key: key);
@override
State<SignUp> createState() => _SignUpState();
}
class _SignUpState extends State<SignUp> {
var emailController = TextEditingController();
var passwordController = TextEditingController();
/* var docId = FirebaseFirestore.instance.collection('users').doc().id; */
final TextEditingController _usernameController = TextEditingController();
final TextEditingController _phoneNumberController = TextEditingController();
final TextEditingController _companyNameController = TextEditingController();
final FirebaseAuth auth = FirebaseAuth.instance;
@override
Widget build(BuildContext context) {
String docId;
docId = emailController.text;
final User? user = auth.currentUser;
double w = MediaQuery.of(context).size.width;
double h = MediaQuery.of(context).size.height;

}Firestore Docs – I want to take this data and display it in the account page shown below
Edit: I have the document ids being set as the users email, I wanted to try an easy way to recall the document per account. If this is wrong please let me know.

Account Page – These are the fields I want to fill with the data, they all say N/A because I have a separate temporary file that uses constants to set those values

Edit: Edited account.dart throws a _CastError

Answer
I have figured out the solution to my issue. In the _AccountState class I added the following lines of code and it seemed to work for me.
I added this above the _AccountState class..
final FirebaseAuth _firebaseAuth = FirebaseAuth.instance
then inside the class I added this code above the build widget..
void _getData() async {
User? user = _firebaseAuth.currentUser;
FirebaseFirestore.instance.collection('users').doc(user?.email).snapshots().listen((userData) {
setState(() {
username = userData.data()!['username'];
companyName = userData.data()!['company_name'];
phoneNumber = userData.data()!['phone'];
emailAddress = userData.data()!['email'];
});
});
}
@override
void initState() {
super.initState();
_getData();
}
After adding that into the state I just declared each variable in the title of my ListTiles and it seemed to work
ListTile(
leading: const Icon(
Icons.person,
color: Colors.black,
),
title: Text("Username: $username"),
trailing: const Icon(Icons.keyboard_arrow_right),
onTap: () {},
),
