Я мучился здесь, чтобы для каждого элемента, созданного в RecyclerView, я составлял внутренний список элементов Chip.И вы знаете, я сделал это, но теперь я мучаю свой сервер с каждой прокруткой этого RecyclerView.Как я могу сделать это, чтобы я не снимал сервер с каждой прокруткой?Вызов сервера происходит в моем случае, когда я вызываю метод getToastFromProduct productRepository
