remask method
      
void
remask()
      
     
    
Revert the mask removal done while reading the code words. The bit matrix should revert to its original state.
Implementation
void remask() {
  if (_parsedFormatInfo == null) {
    return; // We have no format information, and have no data mask
  }
  final dataMask = DataMask.values[_parsedFormatInfo!.dataMask];
  final dimension = _bitMatrix.height;
  dataMask.unmaskBitMatrix(_bitMatrix, dimension);
}
