iOS приложение флаттера не запрашивает разрешения и возвращает статус разрешения неизвестно

Question

Я использую плагин allow_handler 4.4.0 (последнее обновление) для обработки разрешений на мобильных устройствах, который отлично работает на android устройствах, но когда я пытаюсь запросить разрешения на iOS, он не показывает всплывающее окно с разрешениями на устройстве и возвращает статус разрешения неизвестно. Я думаю, что это может отсутствовать в файле info.plist или pod, но я проследил и дважды проверил оба файла, но я не нашел ничего плохого, но я загрузил код для этих файлов, если кто-то найдет что-то отсутствующее или неправильное в файлах. пожалуйста, посмотрите на код и дайте мне знать ваши предложения. Заранее спасибо, ребята.
