How to create a user model in Flutter, convert a DocumentSnapshot from Firebase Firestore into a UserModel object

In this post we are going to discuss how you can create a user model for a flutter app and also convert the DocumentSnapshot from Firebase Firestore into a UserModel object.

To create a user model in Flutter, you can follow these steps:

1. Create a new Dart file and name it user_model.dart.
2. Import the firebase_auth package.
3. Define a class called UserModel.
4. Add the properties that you want to store in your user model.
5. Create a constructor for the UserModel class.
6. Implement the fromDocument method to convert a DocumentSnapshot from Firebase Firestore into a UserModel object.

Here is an example of a user model in Flutter:

import 'package:firebase_auth/firebase_auth.dart';

class UserModel {
  String uid;
  String email;
  String name;

  UserModel({
    required this.uid,
    required this.email,
    required this.name,
  });

  factory UserModel.fromDocument(DocumentSnapshot doc) {
    return UserModel(
      uid: doc.data()['uid'],
      email: doc.data()['email'],
      name: doc.data()['name'],
    );
  }
}

This user model has three properties: uid, email, and name. The uid property is the unique identifier for the user in Firebase Firestore. The email property is the user’s email address. The name property is the user’s name.

The fromDocument method converts a DocumentSnapshot from Firebase Firestore into a UserModel object. This method is useful when you need to retrieve a user model from Firebase Firestore.

Once you have created the user model, you can use it to store user data in Firebase Firestore. You can also use the user model to access user data from Firebase Firestore.
