Is there a way to know that user got back to the app?

I need to know if the user clicked on Back or X and got back to the app. Is there a way?

You can use AppState event Handler to know if your application has come back in foreground.
For Functional component, register AppState.addEventListener('change', handleAppStateChange); in useEffect call
and same thing in componentDidMount for class component.

this is my handleAppStateChange:
const handleAppStateChange = async (nextAppState) => {
console.log('AppState Changed: ', nextAppState);
if (nextAppState === 'active') {
setIsActive(true);
}
if(nextAppState === 'background'){
setIsActive(false);
}
}

Do not forget to unsubscribe for the event.
