 *
 * DropZone which can be used for uploading files.
 *
 * ### usage
 *
 * ```javascript
 * import { DropZone, DropZoneProps } from '@adminjs/design-system'
 * ```
 *
 * how to use it in your custom component.tsx (TypesScript):
 * ```
 * import React, { useState } from 'react'
 * import { DropZone, Label, BasePropertyProps } from '@adminjs/design-system'
 * import { unflatten } from 'flat'
 *
 * const UploadPhoto: React.FC<BasePropertyProps> = (props) => {
 *   const { property, record, onChange } = props
 *
 *   const onUpload = (files: FileList) => {
 *     const newRecord = {...record}
 *     const file = files.length && files[0]
 *
 *     onChange({
 *       ...newRecord,
 *       params: {
 *         ...newRecord.params,
 *         [property.name]: file,
 *       }
 *     })
 *     event.preventDefault()
 *   }
 *
 *   return (
 *     <Box>
 *       <Label>{property.label}</Label>
 *       <DropZone onChange={onUpload} />
 *     </Box>
 *   )
 * }
 * ```
