How to search for user data and retrieve them from firebase with flutter?

Question

I am trying to retrieve user data that I stored on firebase database and compare it to an inputed text "trying to login but with another way ;)" but when I search for examples I can't quite understand their methods of retrieving data they don't retrieve specific data but the collection, so any ideas?

Solution

To get the data you need to do the following:

  void getUserData() async{
    var firebaseUser = await FirebaseAuth.instance.currentUser();
    firestoreInstance.collection("users").document(firebaseUser.uid).get().then((value){
      print(value.data);
    });
  }

Assuming you are using Firebase authentication as the document id

But How can I get the email or the password after and store it in a const

value.data will contain the email and password, you can do value.data["email"] and value.data[password"]

Can I change thw way to search for the document by replacing 'firebase.uid' with any thing else right

[Peter Haddad]

if u have uid as a document id, then you need to use the above in the answer

[omar developer]

what about searching by the username that the user entered, Is it possible?

[omar developer]

Like storing the value of username in a controller and put the controller in firebase.uid
