arkit_pluginを使うアプリケーションの環境構築について

#やりたいこと
Flutterのarkit_pluginを使ってARアプリを作成しようとしています。
その、環境構築の段階でつまづいているので質問させていただきます

なお、こちらの記事を参考に環境を構築しています。

#開発環境
ビルドでは実機を使っています(iphone8)

Catalina:v10.15.6
ios:v13.7
Xcode:v11.7
Flutter SDK:v1.20.2
Android Studio:v4.0

#過程と設定ファイル
参考記事のように
・pubspec.yamlの設定
・/ios/Runner/Info.plistの設定
・Xcodeでの設定
を行い、全てうまくいったように思えました

#エラー
実機でビルドした結果が以下のようになります

Launching lib/main.dart on user_iPhone in debug mode...

Runnerのセッティングが悪いようですが調べてもなかなか出てきませんでした。
Xcodeのセッティングが悪いのでしょうか?

#やったこと
flutter clean
rm ios/podfile
を実行し、再度ビルドしましたが結果は同じでした。

ビルドによって生成されたPodfileはこちらです

# 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

XcodeのGeneralはこのようになります

個人の名前を表示してしまうので一部だけお見せします.必要でしたら画像処理をしてお見せします

また、ios/Runner配下にInfo.plistが存在しないのですが気にしなくてもよろしいのでしょうか？

#追記
gitのログからInfo.plistを復元し、ビルドしましたが別のエラーがでました
