Я некоторое время пытался щелкнуть по изображению, чтобы перейти на другой экран, и ничего не получалось даже после нескольких публикаций.
После нескольких попыток с ошибками и пробами я закончил работу с этими структурами, где экран работает, но по щелчку все, что я вижу, это эффект touchableOpacity
, но без навигации. Может ли кто-нибудь помочь, пожалуйста, это будет по достоинству оценено в этот момент. Спасибо
