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
