How to access details from a method in flutter in firestore

Question

These are the upload details to a Firestore document.

'uid': this._userId,
'Email': this._email,
'Fullname': this._fullname,
'Location': this._location,
'ImageUrl': this._imageurl = await uploadImage(),

Using the code below — if I am correct — I'm trying to access the details of current user using the uid code present in the document.

final user = FirebaseAuth.instance.currentUser();

getData() async {
  return await Firestore.instance
      .collection('userdetails')
      .where('uid', isEqualTo: user)
      .getDocuments();
}

Now, as the method returns the document with the user details of the current user, how can I access each of the values to display on screen.Name and Image URL?

Answer 1

I would not expect that code to work, since user is a FirebaseUser object, and not a UID string. You probably want this instead to use the uid of the current user to filter the results:

Firestore.instance
    .collection('userdetails')
    .where('uid', isEqualTo: user.uid)
    .getDocuments();

Answer 2

Here's how to access those fields:

Firestore.instance.collection('userdetails').document(user.uid).get().then((doc) {
    _fullname = doc.data['Fullname'];
    _imageUrl = doc.data['ImageUrl'];
}
