How do you listen for changes to a formik field?
See original GitHub issue❓Question
I have a UI that I want to respond to the selected values of a formik form. It’s a pricing UI where selecting different options results in a different total price. I need to be able to connect a listener for when a formik field has setFieldValue() called on it. I don’t see such a function in formik so the way I’ve gotten around it is to duplicate the form schema as values in the state and every time I call setFieldValue() I also mutate the corresponding state value in the same way.

Can you just move this logic to your render function and determine price/what fields to show based on
values?I recently needed to subscribe on some value. My input was editable with
handleChangeand also manually withsetFieldValue. So to avoid multiple listeners, I just used hook like this:Cheers
