React-Native Making setInterval Declarative with React Hoo

I'm playing with React Hooks for more than a few hours, I'm probably ran into an intriguing problem: using setInterval just doesn’t work as I'd expect with react-native
function Counter() {
const [time, setTime] = useState(0);
useEffect(() => {
const id = setInterval(() => {
console.log('called');
setTime(time + 1);
}, 1000);
return () => {
console.log('cleared');
clearInterval(id);
};
}, [time]);
return <div>{time}</div>;
}
The code above should clearInterval every time that time
state changes
It works fine on ReactJS
but on React-native
I'm getting an error says "Callback() it's not a function"
It's working as expected in Reactjs
