deserializePayload method

@override int deserializePayload(SmsBuilder builder, ByteData byteData, Endian endianness, int offset,)

Call to deserialize only the payload, no header. The Builder is to allow passing the message to build into. returns a int with a serialized size

Implementation

@override
int deserializePayload(imc.SmsBuilder builder, ByteData byteData,
    Endian endianness, int offset) {
  var byteOffset = offset;

  // field number
  var numberSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var numberDData = List.filled(numberSSize, 0);
  for (var i = 0; i < numberSSize; i++) {
    numberDData[i] = byteData.getUint8(byteOffset++);
  }
  var numberDecoded = utf8.decode(numberDData);
  builder.number = numberDecoded;
  // field timeout
  builder.timeout = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  // field contents
  var contentsSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var contentsDData = List.filled(contentsSSize, 0);
  for (var i = 0; i < contentsSSize; i++) {
    contentsDData[i] = byteData.getUint8(byteOffset++);
  }
  var contentsDecoded = utf8.decode(contentsDData);
  builder.contents = contentsDecoded;

  return byteOffset - offset;
}
