How to pass an object to onSubmit in React Hook Form

I am trying to use a react hook form to create a screen in my react native app. I need to pass my navigation object to my submit function for my routing to work. Here is the example using code from React Hook Form:

function App() {
  const {
    formState: { errors }
  } = useForm();

  const onSubmit = (data) => {
    //Want to be able to access the object here when it is passed as a parameter

  const navigation = {myObject: "My object"}; //Want to pass this to the onSubmit function from the onSubmit call in the form

  return (
    <form onSubmit={handleSubmit(onSubmit)}> //Want to pass the object to the function here
      <input defaultValue="test" {...register("example")} />

      <input type="submit" />

*Took code out for clarity.

So, how can I pass my object into the “onSubmit={handleSubmit(onSubmit)}”?


handleSubmit(onSubmit) means that you’re passing onSubmit by reference and it’s taking the data by default , call the handleSubmit like this :

<form onSubmit={handleSubmit(data => onSubmit(data, navigation))}>

and the object should be available here :

const onSubmit = (data, obj) => {
  console.log(data, obj);
