Как интегрировать JSON Restfull API для входа и регистрации, используя JSON в качестве объекта.

Также дайте мне знать, как установить сеанс после входа пользователя в систему.

Пожалуйста, дайте мне знать, как пропустить страницу входа, если пользователь уже вошел в систему (с помощью Flutter и Дарт)

Мне нужна помощь в создании функции, которая может принимать значения, введенные на моей странице регистрации, и завершать регистрацию, а также необходимо добавить ссылку для проверки электронной почты.
Кроме того, мне нужна помощь в создании функции для входа в систему путем вызова RESTFUL API.
При входе должен быть установлен сеанс, и если пользователь возвращается в приложение после входа в систему, он следует направить на домашнюю страницу, пропуская заставку и страницу входа в систему.

Я создал форму входа с адресом электронной почты, паролем и кнопкой входа.  Я новичок во flutter, dart и Интернете.

Как интегрировать JSON Restfull API для входа и регистрации, используя JSON в качестве объекта.

Также дайте мне знать, как установить сеанс после входа пользователя в систему.

Пожалуйста, дайте мне знать, как пропустить страницу входа, если пользователь уже вошел в систему (с помощью Flutter и Дарт)

Я создал экран входа в систему и экран регистрации, а также экран-заставку

Мне нужна помощь в создании функции, которая может принимать значения, введенные на моей странице регистрации, и завершать регистрацию, а также необходимо добавить ссылку для проверки электронной почты.
Кроме того, мне нужна помощь в создании функции для входа в систему путем вызова RESTFUL API.
При входе должен быть установлен сеанс, и если пользователь возвращается в приложение после входа в систему, он следует направить на домашнюю страницу, пропуская заставку и страницу входа в систему.
