Прошло больше недели, и я изо всех сил пытался заставить его работать.React Native: реквизит и состояние изменено, но не переработано
В нижеследующем коде данные поступают через реквизит (рисунок Редукса) и визуализируются, на самом деле есть оценки, виды форм. когда вы заполняете форму и отправляете ее, она отправляется, реквизит и изменения состояния. (эта форма будет удалена из состояния, реквизит), но форма все еще отображается в представлении. Вызов this.loadData(); в коде не помогает. но PullDownToRefresh работает и обновляет компонент. RefreshControl также звонит this.loadData();
Что я делаю неправильно? Любые решения, пожалуйста? Evaluation.js:

Спасибо за ваш ответ. Я сделал то, что вы сказали, но ничего не изменил. – Ataomega
Я обновил вопрос с остальной частью кода, если вы проверите EvaluationPage, у меня уже есть «connect». – Ataomega
