Reading in a loop - Githubissues

Hi,

First off thank you so much for this great library!

Trying to implement scanning bands in a loop for an event so that we can save time in going back and forth in screens. Here is the sample code that we are trying - scanning seems to go fine in a loop, however I cant seem to get out of the loop :

useEffect(() => {
  const readTag = async () => {
    try {
        NfcManager.cancelTechnologyRequest()
      const newtag = await NfcProxy.readTag();
      if (newtag) {
        const currentMeal = getCurrMeal();
        setCurrentTag(newtag);
        await fetchMealDetails(newtag, currentMeal);
      }
      if (!myError && isContinuousRead && !isLoading) {
        readTag(); // Continue reading if the flag is true
      }
    } catch (ex) {
      console.warn(ex);
      alert('ERROR', 'fail to read tag', [{ text: 'OK' }]);
    }
  };

  if (isContinuousRead && !myError && !isLoading) {
    alert(isContinuousRead);
    readTag();
  }

  return () => {
    setContinuousRead(false); // Cleanup: Set continuous read state to false
  };
}, [currMeal, myError, isContinuousRead, isLoading]);
