[core/no-app] No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp(

[famousuniverse]

Is there an existing issue for this?

• I have searched the existing issues.

Which plugins are affected?

Messaging

Which platforms are affected?

Android

Description

using:
firebase_core: ^3.10.0
firebase_messaging: ^15.2.0

already have:
`Future main() async {

WidgetsFlutterBinding.ensureInitialized();
try {
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);
FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);

} catch (e) {
print("Firebase initialization failed: $e");
}`

seems to be only happening in android, not web and not ios.

Reproducing the issue

flutter run -d 'emulator-5554' --dart-define=ENV=production --debug | grep -v "I/MESA"

Firebase Core version

^3.10.0

Flutter Version

3.27.2

noticed this too:
I/flutter (14995): Firebase initialization failed: PlatformException(channel-error, Unable to establish connection on channel., null, null)

Making an assumption this has to do with a flutter SDK update?

Hi @famousuniverse, I'm unable to reproduce this issue. Could you share a complete example replicating this?

[famousuniverse]

running:
flutter run -d 'emulator-5554' --dart-define=ENV=development --debug | grep -v 'I/MESA'

on a basic app setup, gets:
I/flutter ( 5547): [IMPORTANT:flutter/shell/platform/android/android_context_vk_impeller.cc(60)] Using the Impeller rendering backend (Vulkan).
E/flutter ( 5547): [ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)

With a main.dart file of:
`

import 'package:nameofproject/firebase_options.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/material.dart';

Future main() async {
WidgetsFlutterBinding.ensureInitialized();

// Force Firebase initialization first
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);

}`

and pubspec.yaml:
firebase_core: ^3.10.0 firebase_messaging: ^15.1.2 firebase_core_web: ^2.17.0

By "complete example," I mean a GitHub repository. Please create a new project with minimal code that reproduces the issue and share the link, so I can clone it and investigate further, as I’m unable to reproduce it on my end.
