How to reset form onSubmit in Formik?

Question

I have a form built with Formik. And I would like to reset/ empty it after submit. I've tried to add resetForm(), but it's not working. Here is my code:

onSubmit={(values, { setSubmitting, resetForm }) => {
  setTimeout(() => {
    alert(JSON.stringify(values, null, 2));
    setSubmitting(false);
    resetForm();
  }, 400);
}}

And a live example https://codesandbox.io/s/reset-form-8sw24.

Where is my mistake and how can I reset/ empty form onSubmit?

Answer 1

I had to add value={values.phone} to the input as I'm using a custom input. After that resetForm() is working.
