const component1= (props) => {
const [**selectedCountry**, setSelectedCountry] = useState();
<Dropdown onSelect={eventKey => {
const { code } = countries.find(({ code }) => eventKey === code);
setSelectedCountry(eventKey);
setToggleContents(<><FlagIcon code={code} /> </>);
}}
>
<Dropdown.Menu>
{countries.map(({ code, title }) => (
<Dropdown.Item key={code} eventKey={code}><FlagIcon code={code} /> {title}</Dropdown.Item>
))}
</Dropdown.Menu>
</Dropdown>
.

}
a variable within this component. It becomes setSelectedCountry according to the dropdown change. how can i get this value in component2.js (i need selectedCountry value) ?
export default function component2() {
useEffect(() => {
postService.getLanguage(**HERE VALUE**).then((response)=>{
setData(response.data);
},
(error) => {
console.log(error);
}
);
}, []);
***I will take this value as a parameter and evaluate it in get (selectedCountry)How can I ***
}
Yes, you can use createContext and useContext function here: https://reactjs.org/docs/context.html
Alternatively you can use Redux to help you manage states used by multiple components.
