To reproduce

• Execute expo eject command
• Start APP with expo startcommand
• Error occurs

Codes that cause error

const nfcClean = () => {
	NfcManager.setEventListener(NfcEvents.DiscoverTag, null);
	NfcManager.setEventListener(NfcEvents.SessionClosed, null);
};

const ReadNFC = (scanning, setResult) => {
	const { t } = useTranslation();

	if (scanning) {
		NfcManager.registerTagEvent();
		NfcManager.start().then(() => {
			NfcManager.setEventListener(NfcEvents.DiscoverTag, (tag) => {
				try {
					const arr = tag.ndefMessage[0].payload.slice(3);
					setResult(String.fromCharCode(...arr));
				} catch (error) {
					Alert.alert(t("Error.ReadNFCFailed"), error.toString());
				}
			});
			NfcManager.setEventListener(NfcEvents.SessionClosed, nfcClean);

		return nfcClean;

		NfcManager.unregisterTagEvent();
	}

Description

Currently, my app is not working with expo start command but works with expo run:android or expo run:ios, perhaps this issue is related to the package version?

I'm not using expo, so I don't really aware the difference between expo start and expo run:android. But per my understanding, this might be normal because if we don't rebuild the native part (looks like what expo run:<platform> does), we don't have the native counterpart for our library, and that's the error is talking about.

Maybe you can check the expo doc about whether it rebuild native module and deploy to target while expo start?

BTW, totally off topic but I just find out that you're also from Taiwan! It's good to see another Taiwaness here 🤘 and thanks for your contribution!

It's good to see you here too and thanks for your effort to make this project so I can complete some magical things :)

About the problem I encountered I'll look into expo doc to see if I find anything related
