Я получаю очень странную ошибку, связанную с использованием компонентов, и я понятия не имею, что это значит. Я знаю, что это как-то связано с тем, что я не использую компонент должным образом, и что это нарушение инварианта, но кроме этого, я понятия не имею. Я получаю сообщение об ошибке только на мобильном устройстве, используя приложение expo, но не на P C. Я прикрепил свой код ниже, и любые предложения приветствуются. Спасибо. ошибка
