xcode – Flutter iOS distribution fails with No architectures in the binary

I’ve been building a flutter application and its come time to release to internal testers and I’ve been running into issues. The error I get is this

ERROR ITMS-90085: "No architectures in the binary. Lipo failed to detect any architectures in the bundle executable."
Return status of iTunes Transporter was 1: ERROR ITMS-90085: "No architectures in the binary. Lipo failed to detect any architectures in the bundle executable."
The call to the iTMSTransporter completed with a non-zero exit status: 1. This indicates a failure.

I’ve read many articles online and the main answer is that there is something wrong with my Info.plist. I’ve had a successful build of this project in the early phases before most of my code and packages were integrated into the project and had a successful build. I’ve checked my plist with that commit and nothing major has changed other than adding more to the podfile. I’ve tweaked with them all, including copying over the ios folder from a brand new flutter project and I’m still having issues. I am wondering if there is something wrong with my pod integration? here is my podfile

# Uncomment this line to define a global platform for your project
platform :ios, '10.0'

# 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

and here is my pubspec.yaml
