biFlush method Null safety

void biFlush()

Flush the bit buffer, keeping at most 7 bits in it.

Implementation

void biFlush() {
  if (_numValidBits == 16) {
    _putShort(_bitBuffer);
    _bitBuffer = 0;
    _numValidBits = 0;
  } else if (_numValidBits >= 8) {
    _putByte(_bitBuffer);
    _bitBuffer = (_rshift(_bitBuffer, 8));
    _numValidBits -= 8;
  }
}
