Как я могу использовать новую библиотеку в проекте старой версии? ⇐ IOS

[Anonymous]

Я новичок в Flutter и сейчас столкнулся с ситуацией, когда мне нужно добавить функцию автоматического захвата для распознавания лиц. Однако в проекте используется более старая версия Flutter, которую невозможно обновить, поэтому я не могу интегрировать необходимую библиотеку.
