AsyncFormValue<Request, Response> class sealed

A class that represents the state of a form, inspired by AsyncValue from Riverpod.

This class can be in one of four states:

AsyncFormIdle: The form is in its initial state, not yet submitted.
AsyncFormData: The form has data, which may include initial values, request data, and response data.
AsyncFormError: An error occurred. It contains the error and stack trace, and can preserve previous data.
AsyncFormLoading: The form is in a loading state. It can preserve previous data while loading.
