**Сущность**

**Описание**

`adUnitId`

Используйте:

- **development mode** — для работы с [демоблоками](https://ads.yandex.com/helpcenter/ru/easy/integration/flutter/testing.md#blocks);

- **production mode** — для работы с `R-M-XXXXXX-Y` (уточните реальный ID в интерфейсе Рекламной сети Яндекса). `R-M-XXXXXX-Y` — это вид рабочего рекламного ID, по которому будут приходить разные креативы.
