Ошибка сборки Flutter iOS при запуске установки модуля ⇐ IOS

[Anonymous]

Я пытаюсь создать плагин флаттера, поэтому я создал плагин, выполнив действия, описанные на странице https://flutter.dev/docs/development/pa ... g-packages. Я получаю сообщение об ошибке, когда пытаюсь запустить пример iOS. Ниже приведен журнал, который я получаю при запуске примера приложения для iOS.
Может ли кто-нибудь мне с этим помочь?
