CocoaPods could not find compatible versions for pod "FBSDKLoginKit"

Question

I'm making use of flutter_login_facebook 1.0.1 plugin to enable logging into my app using Facebook.

I'm getting the below error when trying to set up Facebook login on an iOS device.

 pod install
    WARNING: CocoaPods requires your terminal to be using UTF-8 encoding.

[!] CocoaPods could not find compatible versions for pod "FBSDKLoginKit":
  In Podfile:
    flutter_facebook_auth (from `.symlinks/plugins/flutter_facebook_auth/ios`) was resolved to 2.0.0, which depends on
      FBSDKLoginKit (~> 11.0.0)

    flutter_login_facebook (from `.symlinks/plugins/flutter_login_facebook/ios`) was resolved to 0.5.0, which depends on
      FBSDKLoginKit (~> 9.1)

I have tried the below steps that I could find from other posts on stackoverflow but no luck with it:

1. Deleted Pods folder, ios/Podfile file and ios/Podfile.lock file.
2. Executed flutter clean command.
3. Executed flutter pub get command.
4. Tried updating using the following commands pod update FBSDKCoreKit , pod update FBSDKLoginKit and pod repo update .
5. Excuted pod install

Below are the contents of my Podfile :

# Uncomment this line to define a global platform for your project
platform :ios, '11.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

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
  pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '8.0.0'
  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)
  end
end

Please find below details about my flutter and dart version:

删除Podfile.lock并运行pod install --repo-update为我解决了这个错误。

Make sure that you're using an up-to-date version of Flutter and flutter_login_facebook plugin. Then run flutter pub cache repair and flutter pub get to rebuild the references. Alternatively, you can delete pubspec.lock before running flutter pub get to fetch the dependencies.
