import React, {useEffect} from 'react';
import { Link } from 'react-router-dom';
import { useSelector, useDispatch } from 'react-redux';
import { detailsProduct } from '../actions/productActions';
function ProductScreen(props){
const productDetails = useSelector(state => state.productDetails);
const {product,loading,error} = productDetails;
const dispatch = useDispatch();
useEffect(() => {
dispatch(detailsProduct(props.match.params.id));
return () => {
//
}
}, [])
return <div>
<div className="back-to-result">
