A class representing the Form API. It handles the logic and interactions with the form state.
Normally, you will not need to create a new FormApi instance directly. Instead, you will use a framework hook/function like useForm or createForm to create a new instance for you that uses your framework's reactivity model. However, if you need to create a new instance manually, you can do so by calling the new FormApi constructor.
