deserializePayload method

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

  // field flags
  builder.flags = imc.ReferenceBitfieldFlags(byteData.getUint8(byteOffset));
  byteOffset += 1;
  // field speed
  var speedSId = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  if (speedSId == imc.ImcId.nullId) {
    builder.speed = null;
  } else {
    var pMsgBuilder = imc.messagesBuilders[
            imc.idsToMessages[speedSId] ?? imc.ImcId.nullId.toString()]
        ?.call()
        .newInstance(builder);
    var pMsgSerializer = imc.messagesSerializers[
