Original project: https://github.com/MaldonadoAndres/mifare_nfc_classic
Fork making project compatible with (Dart 3) A Flutter plugin for Android for reading and writing NFC cards
- Only Mifare Classic
- Only NfcA technology
- Only works with passwords if sector B
- Requires Android API level 31 or later.
- Add android.permission.NFC to your AndroidManifest.xml.
- Remember that you shouln't write in the sector 0 of any card
- If you write in the 4th block of any sector write down what you write this is the new password for write and read in this sector
- In all cases the password parameter is optional, is only in the case the sector has a custom password
Check NFC Availability
// Check availability
AVAILABILITY isAvailable = await MifareNfcClassic.availability;
switch(isAvailable){
case(AVAILABILITY.AVAILABLE):
//NFC is enabled.
break;
case(AVAILABILITY.NOT_ENABLED):
//The phone support NFC but user has to enable it.
break;
case(AVAILABILITY.NOT_SUPPORTED):
//The phone doesn't support NFC.
break;
}Get Sector or Block Count
int _sectorCount = await MifareNfcClassic.sectorCount;
int _blockCount = await MifareNfcClassic.blockCount;Read a specific Sector
List<String> _sector = await MifareNfcClassic.readSector(sectorIndex: index, password: password)
/*
["FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"]
*/Read a specific Block of a specific Sector
String _block = await MifareNfcClassic.readBlock(blockIndex: _blockIndex, password: password);
/*
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"
*/Read all sectors of a card
Note: This operation take some seconds so leave the card close to the phone like for 2 seconds.
List<List<String>> _card = await MifareNfcClassic.readAll(password: password);
/*
[["FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"],
...
...
...
["FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF",
"FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF"]]
*/Write a specific Block of a specific Sector
bool didWrite = await MifareNfcClassic.writeBlock(blockIndex: _blockIndex, message: _message, password: password);
/*
didWrite indicates if the operation completed successfully or not.
*/Change Password of a Sector
await MifareNfcClassic.changePasswordOfSector(sectorIndex: _sectorIndex, newPassword: _newPassword, password: password);Write Raw Hexadecimal
await MifareNfcClassic.writeRawHexToBlock(blockIndex: _blockIndex, message: rawHex, password: password);
