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? enter image description here

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

user_70154000

You can use the "where" function in firestore

FirebaseFirestore.instance
.collection('users')
.where('email', isEqualTo: your_text_controller)
.get()
.then(...);
