Konsol tidak memaparkan input teks yang saya sediakan

Question

Jadi saya sedang membina borang dalam React menggunakan formik. Saya membuat komponen TextInput yang mengandungi medan input dengan beberapa perubahan. Apabila saya menggunakan changeHandler ia harus mengemas kini nilai yang saya masukkan tetapi tidak. Saya tertanya-tanya sama ada saya perlu membuat beberapa perubahan pada komponen textInput.

ContactForm.jsx

import React, { useState, useMemo } from "react";
import countryList from "react-select-country-list";
import { doc, setDoc, addDoc } from "firebase/firestore";
import { accountReqRef } from "../../Firebase";
import { useFormik } from "formik";

import Alert from "../../shared/components/UIElements/Alert";
import FormSelect from "../../shared/components/UIElements/FormSelect";
import TextInput from "../../shared/components/UIElements/TextInput";

const ContactForm = () => {
  const formik = useFormik({
    initialValues: {
      firstName: "",
      lastName: "",
      email: "",
      company: "",
      jobTitle: "",
      phone: "",
      country: "",
    },
  });

  const options = useMemo(() => countryList().getData(), []);

  const toast = (
    <div className="toast toast-end">
      <div className="alert alert-info">
        <div>
          <span>New mail arrived.</span>
        </div>
      </div>
      <div className="alert alert-success">
        <div>
          <span>Message sent successfully.</span>
        </div>
      </div>
    </div>
  );

  // document submission date
  const current = new Date();
  const date = `${current.getDate()}/${
    current.getMonth() + 1
  }/${current.getFullYear()}`;

  const accountReqDoc = {
    firstName: formik.values.firstName,
    lastName: formik.values.lastName,
    email: formik.values.email,
    company: formik.values.company,
    jobTitle: formik.values.jobTitle,
    phone: formik.values.phone,
    country: formik.values.country,
    subDate: date,
    status: "pending verification",
  };
  console.log(formik);

  //add account request document to accountReq collection

  const addAccReq = () => {
    return <div>ContactForm</div>;
  };

  /*const changeHandler = (country) => {
    setCountry(country);
  };
*/
  return (
    <div className="px-6 w-[700px]">

Firasat saya ialah input anda sama ada tiada id 或 name .

Ini daripada dokumentasi https://formik.org/docs/api/formik#handlechange-e-reactchangeeventany--void

Sebagai contoh

Fikirkan dengan cara ini, handleChangeBagaimana untuk mengetahui medan yang sedang dikemas kini.
