Firestore Utilities

Import the package in your Dart code

import 'package:firebase_utils/entity/firestore_doc.dart';
import 'package:firebase_utils/firebase/firestore_service.dart';

Create an Entity UserInfo which can extends FireStoreDoc or TimeStampedFireStoreDoc. If you need createdDate and updatedDate fields in firestore table then extends with TimeStampedFireStoreDoc.

class UserInfo extends FireStoreDoc {
  final String name;
  final String email;
  final String profileImage;

  UserInfo(
      {required this.name, required this.email, required this.profileImage});

  @override
  Map<String, dynamic> toMap() => <String, dynamic>{
        'name': name,
        'email': email,
        'profileImage': profileImage,
      };

  factory UserInfo.fromMap(Map<String, dynamic> map) => UserInfo(
        name: map['name'] as String,
        email: map['email'] as String,
        profileImage: map['profileImage'] as String,
      );
}

Create a collection reference of users. users is a collection type of UserInfo in firestore db

CollectionReference<UserInfo> get _userCollectionRef =>
      widget._fireStoreService.getCollectionRef(
          'users', (snapshot, _) => UserInfo.fromMap(snapshot.data()!));

Get a instance of FireStoreService to perform all Firestore operations.

final FireStoreService firestoreService =  FireStoreService.getInstance(FirebaseFirestore.instance)

firestoreService.getListStream(_userCollectionRef).listen((event) {
    List<UserInfo> = event
})
