 }
 });

export default App;

When Ever i run the above code i get this error

ERROR Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons: 1. You might have mismatching versions of React and the renderer (such as React DOM) 2. You might be breaking the Rules of Hooks 3. You might have more than one copy of React in the same app

i don't know what could be wrong i will really appreciate if you guys can help me figure this out
