GitHub discussion about this issue - https://github.com/jaredpalmer/formik/issues/529
I passed formik values to a function that is called in <Field/>'s onChange but when I type in the <Field/>, the last character does not fall into the function.

Screenshot:
Minimal Code Instance:
import React from "react";
import ReactDOM from "react-dom";
import { Formik, Form, Field, FieldArray } from "formik";
function App() {
//------ HERE ----------
const getValues = values => console.log(values.fields[0]);
//----------------------
return (
<>
<Formik
initialValues=
onSubmit={(values, actions) => {
actions.setSubmitting(false);
console.log(values);
return false;
}}
render={({ setFieldValue, values }) => (
<Form>
<FieldArray
name="fields"
render={() => (
<Field
type="text"
name="fields.0"
placeholder="Write something"
onChange={e => {
setFieldValue("fields.0", e.target.value);
//---------------
getValues(values);
//---------------
}}
/>
)}
/>
</Form>
)}
/>
</>
);
}
ReactDOM.render(<App />, document.getElementById("root"));
