AppState and getGenericPassword

[ValyaBabenkov]

Good afternoon. Can you please tell me how to implement this approach, always request biometrics (getGenericPassword), when we change AppState to 'active'.

Right now I have a loop, as the FaceID screen - first makes the screen 'inactive', and when it activates successfully it makes it back to 'active' and then the loop goes on.

My code:

useEffect(() => {
        const listenerChangeAppState = async (state: string) => {
            if (state === 'active') {
                const credentials = await getGenericPassword();
....
            }
        };
        const appListener = AppState.addEventListener('change', listenerChangeAppState);
        return () => appListener.remove();
    }, []);

Store the state in a ref when it is changed. Only update it when the state is different from the previous state, and only do this when the state is 'active' or 'background'.
