There's a super easy way of accessing props and helpers like handleSubmit, handleChange, handleBlur, values, errors, etc in Formik. Just wrap your components inside the <Formik>...</Formik> context and you can use the hook to get access to all the props.
Example:
import React from 'react';
import { useFormikContext, Formik, Form, Field } from 'formik';
const AutoSubmitToken = () => {
// Grab values and submitForm from context
const { values, submitForm } = useFormikContext();
React.useEffect(() => {
// Submit the form imperatively as an effect as soon as form values.token are 6 digits long
if (values.token.length === 6) {
submitForm();
}
}, [values, submitForm]);
return null;
};
const TwoFactorVerificationForm = () => (
<div>
{/* .... */}
<Formik
initialValues={{ token: '' }}
validate={values => {
{/* ... */}
}}
onSubmit={(values, actions) => {
{/* ... */}
}}
>
<Form>
<Field name="token" type="tel" />
<AutoSubmitToken />
</Form>
</Formik>
</div>
);
