  formState: Binding<FormState | undefined>,
  formField: string,

  formChanged?: (formState: FormState) => unknown,
): void;

Parameters

• formState — A binding to a form state object (e.g. on an activity).
• formField — The name of the form field to which the value should be bound.
• property — The view property to bind to.
