Flutter build ipa
でこのエラーが発生しました。
原因はPodfileにありました

ダメな方のPodfileのpost_install

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
    end
  end
end

いい方のPodfileのpost_install

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
end
