Flutter - Errors when trying to intialize Firebase with default settings
The DefaultFirebaseConfig
is a custom class, it contains the FirebaseOptions
for each platform:
import 'dart:io';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/foundation.dart';
class DefaultFirebaseConfig {
static FirebaseOptions get platformOptions {
if (kIsWeb) {
// Web
return const FirebaseOptions(
appId: '1:448618578101:web:0b650370bb29e29cac3efc',
apiKey: 'AIzaSyAgUhHU8wSJgO5MVNy95tMT07NEjzMOfz0',
projectId: 'react-native-firebase-testing',
messagingSenderId: '448618578101',
);
} else if (Platform.isIOS || Platform.isMacOS) {
// iOS and MacOS
return const FirebaseOptions(
appId: '1:448618578101:ios:0b650370bb29e29cac3efc',
apiKey: 'AIzaSyAgUhHU8wSJgO5MVNy95tMT07NEjzMOfz0',
projectId: 'react-native-firebase-testing',
messagingSenderId: '448618578101',
iosBundleId: 'io.flutter.plugins.firebasecoreexample',
);
} else {
// Android
return const FirebaseOptions(
appId: '1:448618578101:android:0446912d5f1476b6ac3efc',
apiKey: 'AIzaSyCuu4tbv9CwwTudNOweMNstzZHIDBhgJxA',
projectId: 'react-native-firebase-testing',
messagingSenderId: '448618578101',
);
}
}
}
If you are only targeting Android platform and have added the google-services.json
file then you can just do:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MyApp());
}
without providing the FirebaseOptions
argument.

Previously I getting this No Firebase App '[DEFAULT]' has been created error when trying to copy the code from my previous Flutter project, which required me to import
firebase_core
and runFirebase.initializeApp()
beforerunApp()
.Unfortunately I getting below errors when trying to properly follow the installation instruction here https://pub.dev/packages/firebase_core, caused by unresolvable references on these two lines
import 'package:firebase_core_example/firebase_config.dart'
FirebaseApp app = await Firebase.initializeApp(options : DefaultFirebaseConfig.platformOptions)
So I wonder where that
firebase_core_example
and it'sDefaultFirebaseConfig
class actually came from because I can't find anywhere from pub.dev. Surely the default settings should be allowed because all the required informations has already been included inandroid/app/google-services.json
file. I don't think I need to hardcode it again in Dart file. -
stackunderflow about 2 yearsok tq for the answer. i'll try it

Peter Haddad about 2 years@stackunderflow great, tell me how it goes
-
stackunderflow about 2 yearscall initializeApp without parameters doesn't work for me so i used flutterfire to generate the default config file as per instructions. have you any idea why?

Peter Haddad about 2 yearsDid you use
await
, the flutterfire cli will generate it for you and it's the new way. But the manual way is just two steps literally.. In the cli way you don't have to put the Google-services.json since you specify the options while in the manual way you do have to do add it. But if it works cli then just do that
