Unable to initialize FirebaseApp - Flutter

Question

My project suddenly stopped running properly - it is unable to initialize FirebaseApp.

I've been using an old-fashioned Firebase configuration - Google-Services files directly from Firebase console. I switched to the command flutterfire configure but the error isn't gone. I also tried to delete whole ios directory and try to run flutterfire configure again, but still no results.

Error:

[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)
#0      FirebaseCoreHostApi.initializeCore (package:firebase_core_platform_interface/src/pigeon/messages.pigeon.dart:205:7)

#1      MethodChannelFirebase._initializeCore (package:firebase_core_platform_interface/src/method_channel/method_channel_firebase.dart:29:44)

#2      MethodChannelFirebase.initializeApp (package:firebase_core_platform_interface/src/method_channel/method_channel_firebase.dart:73:7)

#3      Firebase.initializeApp (package:firebase_core/src/firebase.dart:40:31)

#4      main (package:traveler/main.dart:12:3)

Line causing the issue:

  // Placed after WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );

flutter doctor -v:

This issue has happened in the latest firebase_core_platform_interface, so overriding the older version of that would solve the issue for now. (It can be removed once the Firebase team fixes it)

dependency_overrides:
  firebase_core_platform_interface: 4.4.1

user_717919 · Answer

This issue is now resolved in version 1.19.1

firebase_core: ^1.19.1

According to this issue shared by @Hardik Mehta, New SDKs don't compile and old SDK version. A solution that worked for me is to upgrade firebase packages, delete ios/Podfile.lock and run pod install --repo-update.

I have updated the below dependency:

dependency_overrides:
 firebase_core_platform_interface: 4.4.1

Executed this command and updated firebase dependencies

flutter pub upgrade firebase_core

flutter pub upgrade firebase_messaging

it is working properly now.

The problem seems to be with the core platform interface. Add firebase_core_platform_interface: 4.4.0 to pubspec.yaml. You might have to downgrade all other firebase dependencies.

I've the same error but in different context: the app was correctly building and running on both iOS and Android if launched from by Android Studio (even in release mode), but whenever I deployed it using codemagic, I got a non functioning app on the Play Store and App Store that was showing a white screen and giving me the following error:

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: PlatformException(channel-error, Unable to establish connection on channel., null, null)
#0     FirebaseCoreHostApi.initializeCore (package:firebase_core_platform_interface/src/pigeon/messages.pigeon.dart:199)

#1     MethodChannelFirebase._initializeCore (package:firebase_core_platform_interface/src/method_channel/method_channel_firebase.dart:29)

#2     MethodChannelFirebase.initializeApp (package:firebase_core_platform_interface/src/method_channel/method_channel_firebase.dart:73)

#3     Firebase.initializeApp (package:firebase_core/src/firebase.dart:42)

#4     main (package:my_family/main.dart:43)

Codemagic and my android studio were using the same versions of Flutter, Xcode and pod.

I solved the problem adding the following right before dependencies:

dependency_overrides:
  firebase_core_platform_interface: 4.4.0

I'm using old firebase libraries and the version 4.4.1 did not solve the problem.

My firebase libraries:

  firebase_core: 1.12.0
  firebase_auth: 3.3.6
  firebase_storage: 10.2.6
  firebase_messaging: 11.2.6
  cloud_firestore: 3.1.7
