ReactJS : How to read value passed in Link react-router in another functional component

Question

I have followed the suggestion on Pass props in Link react-router

I'm sending Link value to the ReactJS functional component and while accessing it returning empty, I'm sure missing something basic here.

This is my Route path

            <Route path="/report/:id">
                <ReportPage />
            </Route>

The report page which is trying to get value from either query param or state param both returns empty

const ReportPage = (props) => {
    const { query } = useParams();
    const { hello } = useState()

    console.log(query) // Return Empty for Try #2 
    console.log(hello) // Return Empty for Try #1
    console.log(this.props.match.params.hello) // Undefined for 

    return (
        <DashboardLayout>
            <h2> AMI Test Reports </h2>
        </DashboardLayout>
    )
}

DashbaordPage which is Linking

Tried 1 Using the state

                   <Link
                    to={{
                        pathname: "/report/1",
                        state: {
                            hello: "Hello World"
                        }
                    }}>
                    Press Me
                </Link>

Tried #2 using the query

                   <Link
                    to={{
                        pathname: "/report/1",
                        query: "test"
                    }}>
                    Press Me
                </Link>

What is the right way to access the Value passed in the Link in another functional component.

useParams returns an object containing all of the available parameters. What you currently have is useParams returning an object that contains a params property which is incorrect.

what you want:

const { id } = useParams();

As for the location state, you'd get that from useLocation, not useState.

const { state } = useLocation()
