sendCommand method

Future<Iso7816ResponseApdu> sendCommand({ required int instructionClass, required int instructionCode, required int p1Parameter, required int p2Parameter, required Uint8List data, required int expectedResponseLength, })

Sends a command APDU assembled from its fields.

The four header fields are each one byte. expectedResponseLength is the Le field: 1-65536, or -1 for a command that expects no response data. Zero is not a way to say that, and anything else throws PlatformException(code: 'invalidParameter').

Implementation

  required int expectedResponseLength,
}) async {
  final response = await iosApi.iso7816SendCommand(
    _handle,
    instructionClass,
    instructionCode,
    p1Parameter,
    p2Parameter,
    data,
    expectedResponseLength,
  );
  return _toApdu(response);
