android library

The Android surface: everything android.nfc offers and this package exposes.

Every symbol here throws on iOS. Import it with a prefix when you also import package:nfc_util/ios.dart.

import 'package:nfc_util/android.dart' as android;

final classic = android.MifareClassic.from(tag);
if (classic != null && await classic.authenticateSectorWithKeyA(sectorIndex: 1, key: key)) {
  print(await classic.readBlock(blockIndex: 4));
}

Classes

HostCardEmulation

Host card emulation: the phone answers a reader as if it were a contactless card.

IsoDep

ISO 14443-4, the APDU transport. Android only; iOS exposes it as Iso7816.

MifareClassic

NXP Mifare Classic. Android only -- iOS cannot talk to these tags at all, which is an Apple restriction rather than a gap in this package.

MifareUltralight

NXP Mifare Ultralight. Android only; iOS reaches these through MiFare.

NdefAndroid

What Android reports about a tag's NDEF support beyond what the cross-platform Ndef exposes.

NdefFormatable

A tag that can be formatted to hold NDEF but has not been yet. Android only: CoreNFC has no equivalent, so an unformatted tag cannot be prepared from iOS.

NfcA

ISO 14443-3A. Android only.

NfcB

ISO 14443-3B. Android only.

NfcBarcode

A Kovio barcode tag. Android only.

JIS 6319-4, the FeliCa transport. Android only; iOS exposes FeliCa as FeliCa instead.

NfcUtilAndroid

The raw Android surface.

NfcV

ISO 15693. Android only; iOS exposes it as Iso15693 with typed commands instead.
