FirebaseFirestore not recognized by Flutter (Android Studio)

Question

Here is my code, slightly adapted from the example in flutter documentation:

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';
import 'package:firebase_core/firebase_core.dart';

@override
Widget build(BuildContext context) {

CollectionReference items = FirebaseFirestore.instance.collection('item');

return FutureBuilder<DocumentSnapshot>(
  future: items.doc(itemId).get(),
  builder:
      (BuildContext context, AsyncSnapshot<DocumentSnapshot> snapshot) {

    if (snapshot.hasError) {
      return Text("Something went wrong");
    }

    if (snapshot.connectionState == ConnectionState.done) {
      Map<String, dynamic> data = snapshot.data.data();
      return data['out_of_stock_location_ids'];// ${data['last_name']}");
    }

    return Text("loading");
  },
);

}

The code "FirebaseFirestore" is giving an error as it's not recognized as part of library that I'm imported. The import 'package:firebase_core/firebase_core.dart'; is grayed out, possibly inappropriately so. I can't find where on the internet I can find why this is occurring or what to do about it.

If you are using cloud_firestore: 0.14.0 version and above you need to use FirebaseFirestore & doc() then if cloud_firestore: 0.13.7+1 and below you need to use Firestore & document().

The documentation you mentioned is updated and I believe you are using now the lower version of cloud_firestore. If you want to use the higher or latest version of cloud_firestore you must change the version of your firestore in pubspec.yaml then visit the changelog of firestore in pub.dev to see the every changes and update of firestore.

I'm not sure but you probably didn't initialize firebase in your main method you had to use firebase core for initialization

import core to main.dart

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

It appears that the documentation is outdated. I had to change FirebaseFirestore to Firestore and doc to document. I'm not sure how people are supposed to know to do that.

Go to this website=>

Copy the terminal code => flutter pub add cloud_firestore

after paste over your terminal and hit enter.
