Fetch user data from firestore and show them in profile screen using flutter

Question

The issue here is that when I fetch the data, I am suppose to fetch it for the current user but it is rather fetching data for all users within that collection.

I have done reading and watched a number of videos for a possible solution but I can't seem to find how to do this. Your help is needed please. Thanks.

A excerpt of the bode is below.

---

File image;

  TextEditingController loginNameController = TextEditingController();
  TextEditingController loginPhoneController = TextEditingController();
  TextEditingController loginAddressController = TextEditingController();

  clearForm() {
    setState(() {
      image = null;
      loginNameController.clear();
      loginPhoneController.clear();
      loginAddressController.clear();
    });
  }

  //=====> FOR INSTANCES OF FIREBASE <=====
  final auth = FirebaseAuth.instance;
  final db = FirebaseFirestore.instance;
  User user = FirebaseAuth.instance.currentUser;

              )

The collection name is members

Answer 1

First of All use a DocumentSnapshot Shown below:

StreamBuilder<DocumentSnapshot> 

Make a collection to get current user Profile data.

db.collection("Users").doc(user.uid).snapshots();

Remove ListView.builder

To get an Email Address use the below Line

Text('${streamSnapshot.data['Email Address']}'),

By the way I sol this problem with the help of a Professional Flutter Developer SHAKIR ZAHID [shakirzahid191@gmail.com].

Answer 2

Try like this, stream of your widget should be like this, as said above.

db.collection("Users").document(user.uid).snapshots();

for length in Listview.builder, change it too

snapshot.data.length;

And last, All the data which you fetch data like this should change into

from:

snapshot.data.documents[index].get("image")

To:

snapshot.data["image"]

Note I didn't test it. So, it might or might not work.
