Sending data from handleSearch function!

Question

Hey Everyone!
How do I go about sending the data from this handleSearch function in the parent class to a child class?

const [data, setData] = useState(initialData);
const [searchFlight, setSearchFlight] = useState(false);
const [flights, setFlights] = useState([]);

const handleSearch = async() => {
try{
let res = await API.search(data)
setSearchFlight(true);
toggleModal();
setFlights(res.data)
return {data};
} catch (e) {
console.log(e.message)
}}
