Next.js Error : Hydration failed because the initail UI does not match what was rendered on the server.

Error :
Why :
While rendering your application, there was a difference between the React tree that was pre-rendered from the server and the React tree that was rendered during the first render in the browser (hydration).
Solution :
import { useState, useEffect } from 'react'
export default function App() {
const [isClient, setIsClient] = useState(false)
useEffect(() => {
setIsClient(true)
}, [])
return <h1>{isClient ? 'This is never prerendered' : 'Prerendered'}</h1>
}
