useFormikContext() is a custom React hook that will return all Formik state and helpers via React Context.
Here's an example of a form that works similarly to Stripe's 2-factor verification form. As soon as you type a 6 digit number, the form will automatically submit (i.e. no enter keypress is needed).
A custom React Hook that returns Formik states and helpers via React Context. Thus, this hook will only work if there is a parent Formik React Context from which it can pull from. If called without a parent context (i.e. a descendent of a
<Formik> component or
withFormik higher-order component), you will get a warning in your console.
