🐛 [CLOUD_FIRESTORE] The service is currently unavailable.

Bug report

I'm try to use Firestore with Flutter Deskop (MacOS). But I'm getting always this error since my first try for a month.

[cloud_firestore/unavailable] The service is currently unavailable. This is a most likely a transient condition and may be corrected by retrying with a backoff.

Steps to reproduce

1. Created iosApp on Firebase and downloaded GoogleService-Info.plist file to macos project
2. AppBundle (in Runner.xcworkspace) is edited like on Firebase
3. Creted a collection and document on Firebase (myCollection/myDocument)
   (All steps on https://firebase.flutter.dev/docs/installation/macos)

Expected behavior

I wish to get name value from myDocument on Firebase

Hi @kaiserleka,
Can you create a fresh Flutter project and try below steps to see if it works ?

1. Setup a default Flutter project.
2. Add cloud_firestore and firebase_core to pubspec.yaml.
3. Create a project in Firestore. Create a collection. Create a single simple document in that collection.
4. Follow the instructions at https://firebase.flutter.dev/docs/installation/macos to install GoogleService-Info.plist file.
5. Initialize Firebase, following the FutureBuilder / Stateful example here: https://firebase.flutter.dev/docs/overview/#initializing-flutterfire
6. Add import 'package:cloud_firestore/cloud_firestore.dart';
7. Use your code sample provided above.
8. Run app and see if you still get same error ?

Thanks.

Hi @kaiserleka,
Can you create a fresh Flutter project and try below steps to see if it works ?

1. Setup a default Flutter project.

I have created a new Flutter project and enabled desktop support.

2. Add cloud_firestore and firebase_core to pubspec.yaml.

I have added both of that packages to pubspec.yaml

3. Create a project in Firestore. Create a collection. Create a single simple document in that collection.

I have created new Firestore project and created a collection named "testCollection"

4. Follow the instructions at https://firebase.flutter.dev/docs/installation/macos to install GoogleService-Info.plist file.

4.1 I have name my named my project

5. Initialize Firebase, following the FutureBuilder / Stateful example here:
   https://firebase.flutter.dev/docs/overview/#initializing-flutterfire

I have located that stateful example onto my main.dart. When I run it, it works

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

void main() {
  runApp(MaterialApp(home: App()));
}

class App extends StatefulWidget {
  _AppState createState() => _AppState();
}

class _AppState extends State<App> {
  // Set default `_initialized` and `_error` state to false
  bool _initialized = false;
  bool _error = false;

  // Define an async function to initialize FlutterFire
  void initializeFlutterFire() async {
    try {
      // Wait for Firebase to initialize and set `_initialized` state to true
      await Firebase.initializeApp().catchError((e) => print(e));
      setState(() {
        _initialized = true;
      });
    } catch (e) {
      // Set `_error` state to true if Firebase initialization fails
      print(e);
      setState(() {
        _error = true;
      });
    }
  }

  @override
  void initState() {
    initializeFlutterFire();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    // Show error message if initialization failed
    if (_error) {
      print("_error : " + _error.toString());
      return Scaffold(
        body: Center(
          child: Text("Error: " + _error.toString()),
        ),
      );
    }

    // Show a loader until FlutterFire is initialized
    if (!_initialized) {
      return Scaffold(
        body: Center(
          child: CircularProgressIndicator(),
        ),
      );
    }
    return Scaffold(
      body: Center(
        child: Text("initialized"),
      ),
    );
  }
}

6. Add import 'package:cloud_firestore/cloud_firestore.dart';

I have added

7. Use your code sample provided above.

I have updated my code with firestore. Event I run Firebase.initializeApp(), it says "[core/no-app] No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp()"

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

void main() {
  runApp(MaterialApp(home: App()));
}

class App extends StatefulWidget {
  _AppState createState() => _AppState();
}

class _AppState extends State<App> {
  // Set default `_initialized` and `_error` state to false
  bool _initialized = false;
  bool _error = false;

  // Define an async function to initialize FlutterFire
  void initializeFlutterFire() async {
    try {
      // Wait for Firebase to initialize and set `_initialized` state to true
      await Firebase.initializeApp().catchError((e) => print(e));
      setState(() {
        _initialized = true;
      });
    } catch (e) {
      // Set `_error` state to true if Firebase initialization fails
      print(e);
      setState(() {
        _error = true;
      });
    }
  }

  @override
  void initState() {
    initializeFlutterFire();
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    // Show error message if initialization failed
    if (_error) {
      print("_error : " + _error.toString());
      return Scaffold(
        body: Center(
          child: Text("Error: " + _error.toString()),
        ),
      );
    }

    // Show a loader until FlutterFire is initialized
    if (!_initialized) {
      return Scaffold(
        body: Center(
          child: CircularProgressIndicator(),
        ),
      );
    }
    CollectionReference users =
        FirebaseFirestore.instance.collection('testCollection');
    return Scaffold(
      body: Center(
        child: Column(children: [
          Text("initialized"),
          Divider(),
          FutureBuilder<DocumentSnapshot>(
            future: users.doc("testDocument").get(),
            builder: (BuildContext context,
                AsyncSnapshot<DocumentSnapshot> snapshot) {
              if (snapshot.hasError) {
                print(snapshot.error.toString());
                return Text(snapshot.error.toString());
              }

              if (snapshot.connectionState == ConnectionState.done) {
                Map<String, dynamic> data = snapshot.data.data();
                return Text("Value: ${data['testField']}");
              }

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

@kaiserleka,
Since firebase_core is the first and foremost important plugin after migration, initializing it is the first step to integrate firebase in your app. You can do that inside main() method itself, like below and see if it works for you.

void main() async {
  await Firebase.initializeApp();
  runApp(MyApp());
}

I'm getting : [core/not-initialized] Firebase has not been initialized. Please check the documentation for your platform.

bool isFirebaseReady = true;
void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp().catchError((e) {
    isFirebaseReady = false;
    print(e);
  });
  runApp(MaterialApp(home: App()));
}

Why I can't find any complete Flutter Firestore Macos project :(
