Here's an illustrative example of how to utilize mfcard:

import 'package:mfcard/mfcard.dart';

void main() async {
  // Creating a Mifare Classic card reader
  var reader = MifareClassicReader();

  // Opening a Mifare Classic card
  var card = await reader.connect();

  // Reading card information
  var info = await card.readInfo();
  print(info);

  // Writing data to the card
  await card.writeData(0x00, [0x01, 0x02, 0x03]);

  // Closing the Mifare Classic card
  await reader.close();
}

In this example, a Mifare Classic card reader is created and connected to a Mifare Classic card. Following that, card information is read and data is written to the card. Finally, the Mifare Classic card is closed.
