A class representing the API for managing a form field.
Normally, you will not need to create a new FieldApi instance directly. Instead, you will use a framework hook/function like useField or createField 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 FieldApi constructor.
