Flutter pod file issues

Question

its seems that my pod file is broken and I can't install app on my iPhone. I got error pod file "Running pod install Exited (sigterm) Exception: Error running pod install". I have already tried with remove old pod file, flutter clean, flutter get packages and build for iOS again and got the same error. You can find my pod file and pubspec.yaml below and there are no error in pubspec.yaml after a build. Any suggestion on how I can fix this error?

Pod file:

    # Uncomment this line to define a global platform for your project
    # platform :ios, '9.0'
    
    # 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
      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

also can help

rm -Rf ios/Podgfile.lock
pod install --repo-update

Answer 2

In my case, neither of the solutions were working, and I was at a loss. However, after trying everything, I finally found a solution that worked for me.

To resolve the issue, follow these steps:

1. Locate the podhelper.rb file in your Flutter SDK installation. The file should be located at path/to/flutter-sdk/packages/flutter_tools/bin/podhelper.rb.
2. Open the podhelper.rb file in a text editor.
3. Look for the line return [] unless File.exists? file_path.
4. Replace File.exists? with File.exist?, so the line becomes return [] unless File.exist? file_path.
5. Save the changes to the podhelper.rb file.

Answer 3

Solved it with:

flutter upgrade 
flutter clean
flutter pub get
rm -Rf ios/Pods
rm -Rf ios/.symlinks
pod cache clean --all
rm -Rf ios/Flutter/Flutter.framework
flutter build ios
