Quiero manejarlo con formik y base64

const [postImage, setPostImage]: cualquiera = React.useState({ miArchivo: '', })

 const convertToBase64 = (file: any) => { return new Promise((resolve, reject) => { const fileReader = new FileReader() fileReader.readAsDataURL(file) fileReader.onload = () => { resolve(fileReader.result) } fileReader.onerror = (error) => { reject(error) } }) } const handleFileUpload = async (e: any) => { const file = e.target.files[0] const base64 = await convertToBase64(file) setPostImage({...postImage, myFile: base64}) }

<input type='file' multiple className='form-control' name='images' accept='.jpeg, .png, .jpg' // value={props.postImage.myFile} onChange={uploadImage} />
