fatal error: module 'firebase_core' not found

Just created a new flutter project, added google-services-info.plist file to iOS and added firebase_core to pubspec.yaml. Ran the project and got this error. Error: fatal error: module 'firebase_core' not found @import firebase_core;

I have searched a lot on the stack overflow and gitlab. Tried all the workarounds like flutter clean, update repo, delete pod and reinstall pod but still got no success in resolving this error.

This has blocked me for 5 days. Unable to find anything on this. Please help.

Link to my project on GitHub. : https://github.com/infonotics/stocklyticsSO Do add your own googleService-Info.plist file to the Runner folder. I have removed my file for security reasons.

Thanks in advance.

Same error happened when using Firebase authentication.

Before that, while setting up Firebase for iOS initially (i.e. pod installing for @@react-native-firebase/app) I have gotten the following error: 'The Swift pod 'FirebaseCoreInternal' depends upon 'GoogleUtilities', which does not define modules'. I have solved it by adding pod 'GoogleUtilities', :modular_headers => true; in the Podfile as it is suggested when error displayed.

For the Module 'FirebaseCore' not found error, following method worked for me:

  • Adding this line in Podfiles: pod 'FirebaseCore', :modular_headers => true
  • At the project root directory: cd ios && pod install --repo-update
  • Rebuild project: cd .. && npx react-native run-ios

Related part of my Podfiles at the end:

 target 'MyApp' do
   config = use_native_modules!

   # Flags change depending on the env values.
   flags = get_default_flags()

   pod 'GoogleUtilities', :modular_headers => true
   pod 'FirebaseCore', :modular_headers => true

My setup:

OS: macOS Big Sur 11.7.10
Mac: MacBook Pro 13'' Mid 2014
Xcode: 13.2.1
React Native: 0.72.6
@react-native-firebase/app: 18.6.1
@react-native-firebase/auth: 18.6.1

The iOS version in deployment info has to match with the version declared in the Podfile.

platform :ios, '12.4'

I assume you have tried opening the ios project in xcode. When opening the project in XCode, make sure you open the file with the .xcworkspace extension instead of the one with .xcodeproj and then build again.

Its always a tense moment to try everything and if something does not work.

Tried ffi solution, recreating ios folder via flutter create also did not work.

Finally, it worked by closing xcode , flutter clean and then the usual.

One point to note was Identity and Type should be set to Absolute path. I am not sure if that fixed the issue.

You need to download and update the packages in the Podfile.

  1. Open Terminal
  2. cd ./ios
  3. pod update

  unless File.exist?(generated_xcode_build_settings_path)
    raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
