Вы можете скопировать полный код вставки и вставки ниже
Шаг 1: Вы можете определить Building класс, имеющий атрибут id, name, place
Шаг 2: Список поиска возврата не возвращается List<Uiitem>
Шаг 3: Используйте GridView.builder и верните Uiitem(_searchList[index]);
Шаг 4: Uiitem примите Building, чтобы ваш InkWell смог получить id
