Flutter on iOS: Fatal Error: Module 'Cloud_Firestore' Not Found

Flutter on IOS: fatal error: module 'cloud_firestore' not found

If you are using Android Studio the error might occur if you are creating the Podfile manually.
Flutter runs using just the pubspec.yaml file. You don't have to set up the Podfile by yourself. If you follow the installation guideline on the firestore homepage just skip everything after adding GoogleService-Info.plist file using Xcode.

Flutter (iOS) - Module 'cloud_firestore' not found in GeneratedPluginRegistrant.m

Finally after days of trying and error, I found a way to work it out..

So, I noticed several things that might cause an error when building for iOS.

1. Never run the command pod install manually.

2. Do not add the line pod install Firebase to your podfile. Instead, just override all of the firebase dependencies using $FirebaseSDKVersion = '8.0.0'

3. Don't forget to specify your iOS Deployment target on your podfile and match it with the deployment target on your Runner.xcworkspace file (Both in the runner and in the target)

So, if you already have a project, here are the steps I recommend, as this works perfectly for me:

1. Delete the Pods directory, the /ios/podfile.lock, and the ios/Flutter/Flutter.podspec

2. Run pod deintegrate

3. Delete all of the contents inside your DerivedData folder.. you can run rm -rf ~/Library/Developer/Xcode/DerivedData/*

4. Run flutter clean

5. Run flutter pub get

6. Run flutter build ios. Note thas this will also run the pod install command.

7. Close your editor, and open your Runner.xcworkspace on XCode and run your XCode. Clean your build folder. If there's an option to update your project settings, accept it.

You might get several warnings about deprecated functions, but in my case, my app run just fine..

I don't know about the details on why it happened, but from what I noticed, Cocoapods have a different version of some of the firebase packages for ios.. I hope someone can explain it..

Things to note :

• If build your app on XCode, and then use flutter run either on terminal or VSCode, you would get some warnings like Class AMSupportURLConnectionDelegate is implemented in both. So, from my personal experience, I always run my app from XCode.

• If you use Google Sign In, follow the steps here you don't need to add anything in your podfile.

For reference, here is my podfile content.

# Uncomment the next line to define a global platform for your project
 # platform :ios, '12.0'

ENV['COCOAPODS_DISABLE_STATS'] = 'true'

$FirebaseSDKVersion = '8.0.0'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def flutter_root
  generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
  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"
  end

  File.foreach(generated_xcode_build_settings_path) do |line|
    matches = line.match(/FLUTTER_ROOT\=(.*)/)
    return matches[1].strip if matches
  end
  raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end

require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)

flutter_ios_podfile_setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
     config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '12.0'
     config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
    end
  end
end

I hope it works for you! Goodluck!
