serializePayload method

@override int serializePayload(Sms? message, ByteData byteData, int offset)

Call to serialize only the payload, no header, returns a int with a serialized size

Implementation

@override
int serializePayload(imc.Sms? message, ByteData byteData, int offset) {
  if (message == null) return 0;

  var byteOffset = offset;

  // field number
  var numberEncoded = utf8.encode(message.number);
  var numberSSize = numberEncoded.length;
  byteData.setUint16(byteOffset, numberSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in numberEncoded) {
    byteData.setUint8(byteOffset++, b);
  }
  // field timeout
  byteData.setUint16(byteOffset, message.timeout, imc.endianSer);
  byteOffset += 2;
  // field contents
  var contentsEncoded = utf8.encode(message.contents);
  var contentsSSize = contentsEncoded.length;
  byteData.setUint16(byteOffset, contentsSSize, imc.endianSer);
  byteOffset += 2;
  for (var b in contentsEncoded) {
    byteData.setUint8(byteOffset++, b);
  }

  return byteOffset - offset;
}
