Firebase Firestore, How to best practice

I am new to Firebase and try to use the Firestore.

My goal is, to simply put some data in and out of the database.

My database looks like:
Collection: user
Document: userID
Content: 
  forename: Steve
  surename: Bobbins

If i'll try to acces the "forename", how would i do this on the most efficient way? I am somewhat confused with the snapshot stuff and here's how i'm going so far:

DocumentSnapshot doc = await FirebaseFirestore.instance.collection("user").doc("21938103").snapshots().first;
print(doc["surname"]);

I know there is only one document with this id, but i am not sure if there are better ways to handle this.

FirebaseFirestore.instance.collection("user").doc("21938103").snapshots().listen(
 (event){
  String forename = event.get('forename');
  print(forename);
});

If you want a specific field like forename, you use .get('forename'), or the name of field you want. If you want the entire document, you use:

Map<String, dynamic> _map = event.data() as Map<String, dynamic>;
print(_map['forename']);
print(_map['surename']);
