Hi there, can you show me a snippet of what you are doing and can you confirm you have followed the setup instructions here https://firebase.google.com/docs/flutter/setup?platform=android ?

I got the same issue when using firebase_core: 3.15.2
This is the code that throw the error:

 await Firebase.initializeApp(
        options: DefaultFirebaseOptions.currentPlatform);

Just to give an update:
The issue disappeared after I ran this command:

flutter clean && flutter pub get

[benjigold]

We are getting this same issue in our project. We noticed this problem last week and no code changes were made to our repo. We have done pretty through cleaning and re-installing of dependencies with no luck. @thanhdatvo we didn't run that command together but we typically run through the following steps when switching between different projects that we manage:

Delete pubspec.lock file
Delete Podfile.lock file
Delete Pods folder

Then in Terminal:

flutter pub cache clean
flutter clean
flutter pub get
cd ios
pod deintegrate
pod cache clean --all
pod install (if script yells at you to run pod install --repo-update, do that instead)

Also delete Derived Data folder

^^^
These steps have been learned from tons of headaches around switching projects and navigating build/dependency related errors.

We are on:

firebase_core version: 3.15.0
flutter version: 3.24.2

Curious to know if this is a wider problem and is happening to more people. We are going to try to upgrade firebase_core and/or pigeon and see if that helps. Any insight would be greatly appreciated!

@benjigold my current flutter version:

Flutter 3.34.0-0.0.pre • channel beta
