React: How to add onChange functionality inside of Function component? Need onClick event from a checkbox to influence input state

I have a functional component with a checkbox and an input. I'm trying to create an onChange function for the checkbox that clears the input and disables it whenever a user clicks it.

Additionally I'm also trying to add functionality to the input so that a user can delete the pre existing value and type something new. I know that you would typically achieve this with a class component but I'm wondering if there's any way to achieve this within a function component? I have my current component listed below

import React from 'react'
import PropTypes from 'prop-types'
import styled from 'styled-components'
import {
  Col, Row, Icon, Input, Tooltip
} from 'antd'
import Checkbox from '../elements/Checkbox'

const CustomerDetails = ({ customer }) => {
  if (customer === null) {
    return (
      <Container>
        <Row>
          <Col span={24}>
            <ErrorContainer>
              <Icon type="exclamation-circle" />
            </ErrorContainer>
          </Col>
        </Row>
      </Container>
    )
  }

  return (
    <Container>
      <h2>{customer.contact.name}</h2>
      <Row>
        <Col span={8}>
          <H3>
            <strong>Primary Contact:</strong>
          </H3>
          <P>{customer.contact.name}</P>
          <P>{customer.contact.phone}</P>
        </Col>
        <Col span={8}>

          <P>
            {customer.site.city},&nbsp;{customer.site.state}&nbsp;
            {customer.site.postalCode}
          </P>
        </Col>
        <Col span={8}>
          <H3>
            <strong>Billing Address:</strong>
          </H3>
