Deserializing block header has one byte left

[RdeWilde]

I tried deserializing the block headers using the provided tests, but there was one byte left per header.
https://github.com/dartcoin/dart-bitcoin/blob/master/lib/src/core/block_header.dart#L105

I'm not sure if the byte left is a 00 byte dividing the headers? Or is is the txs count?
I modified it like this:

  void bitcoinDeserialize(bytes.Reader reader, int pver) {
    version = readUintLE(reader);
    previousBlock = readSHA256(reader);
    merkleRoot = readSHA256(reader);
    timestamp = readUintLE(reader);
    difficultyTarget = readUintLE(reader);
    nonce = readUintLE(reader);
    reader.readByte(); // 00 byte
  }

Is this right, or is there a better place/way to do it?

I could also add it here instead:
