Я пытаюсь получить данные от одного пользователя и отправить те же данные другому пользователю. Я не уверен, что нужно указать в качестве аргумента в child, чтобы он ссылался на те же данные, и я могу получить и показать данные другому пользователю для утверждения. Я могу отправить изображение, но для полей данных, таких как посетитель, мобильный и плоский, не знаю, что делать.
Мой код выглядит следующим образом.
