The getter 'instance' isn't defined for the type 'Firestore'

Question

Hi guys when i\'m trying to declare a instance of Firestore he give this error ! all that\'s happening after i upgrade my Flutter to last version

Answer 1

Starting from cloud_firestore version 0.14.0:

In the newest version of cloud_firestore, the class Firestore was deprecated now you have to use FirebaseFirestore, so just do:

Import the package:

import 'package:cloud_firestore/cloud_firestore.dart'

To create an instance:

final databaseReference  = FirebaseFirestore.instance;

Other Links Regarding The Changes on Firebase:

No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp() in Flutter and Firebase

Undefined class 'FirebaseUser'
