What Is wrong With My code cause form state always back to initial value or it always create new instance of “forms” class

interface loginComponentProps {}

const LoginComponent: FC<loginComponentProps> = () => {
 
 const [loggedIn, setloggedIn] = useState(false);
 const [form, setFormInstance] = useState(new forms({ userName: '', password: '' } as LoginDto,
 [
 { Key: 'userName', validationFunc: Validations.isRequird },
 { Key: 'password', validationFunc: Validations.isRequird },
 ]))
..........
 return (
 <ImageBackground/>  
     ..........
 </ImageBackground>
 );
};
