Answer 1

This did it for me you can checkout

firebase.firestore().collection("Users")
      .doc(data.uid).set(data)
      .then(result => {

       console.log('User added!');
       
       });

You can get the current user id and place it inside your addUser function like this:

FirebaseAuth auth = FirebaseAuth.instance;
final userId;

if (auth.currentUser != null) {
  print(auth.currentUser.uid);
  userId = auth.currentUser.uid;
}

Place the user id inside your user function

Future<void> addUser(userId) {
      // Call the user's CollectionReference to add a new user
      return users
          .add({
            'full_name': fullName, // John Doe
            'company': company, // Stokes and Sons
            'age': age // 42
            'uid': userId
          })
          .then((value) => print("User Added"))
          .catchError((error) => print("Failed to add user: $error"));
    }
