Flutter pod file issues - file

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

# To add assets to your application, add an assets section, like this:
assets:
- assets/images/
- assets/icons/
# - images/a_dot_ham.jpeg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.dev/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
fonts:
- family: Oxygen
fonts:
- asset: fonts/Oxygen-Regular.ttf
- asset: fonts/Oxygen-Bold.ttf
weight: 700
- asset: fonts/Oxygen-Light.ttf
weight: 300
# For details regarding fonts from package dependencies,
# see https://flutter.dev/custom-fonts/#from-packages
