update method

@override void update(Uint8List inp, int inpOff, int len)

Implementation

@override

  var offset = inpOff;
  var remaining = len;
  while (remaining > 0) {
    final toCopy = (_blockSize - _bufferPos) < remaining
        ? (_blockSize - _bufferPos)
        : remaining;
    _buffer.setRange(_bufferPos, _bufferPos + toCopy, inp, offset);
    _bufferPos += toCopy;
    offset += toCopy;
    remaining -= toCopy;
    _totalLength += toCopy;
    if (_bufferPos == _blockSize) {
      _processBlock(_buffer);
      _bufferPos = 0;
    }
  }
