nfc_util

A Flutter plugin providing access to NFC features on Android and iOS.

Setup

Android

Add android.permission.NFC to your AndroidManifest.xml.

iOS

Add Near Field Communication Tag Reader Session Formats Entitlements to your entitlements.
Add NFCReaderUsageDescription to your Info.plist.
Add com.apple.developer.nfc.readersession.iso7816.select-identifiers to your Info.plist as needed.
Add com.apple.developer.nfc.readersession.felica.systemcodes and com.apple.developer.nfc.readersession.iso7816.select-identifiers to your Info.plist as needed.

Usage

Handling Session

// Check availability
bool isAvailable = await NfcManager.instance.isAvailable();

// Start Session
NfcManager.instance.startSession(
  onDiscovered: (NfcTag tag) async {
    // Do something with an NfcTag instance.
  },
);

// Stop Session
NfcManager.instance.stopSession();

Handling Platform Tag

The following platform-tag-classes are available:

Ndef
FeliCa (iOS only)
Iso7816 (iOS only)
Iso15693 (iOS only)
MiFare (iOS only)
NfcA (Android only)
NfcB (Android only)
NfcF (Android only)
NfcV (Android only)
IsoDep (Android only)
MifareClassic (Android only)
MifareUtralight (Android only)
NdefFormatable (Android only)

Obtain an instance by calling the factory constructor from on the class. For example:

Ndef? ndef = Ndef.from(tag);

if (ndef == null) {
  print('Tag is not compatible with NDEF');
  return;
}

// Do something with an Ndef instance
