Dart crclib #
This is not an official Google product.
Generic CRC calculations as Dart converters and some common algorithms.
The easiest way to use this library is to call
convert on the instance of
the desired CRC routine.
new Crc32Zlib().convert(UTF8.encode('123456789')) == 0xCBF43926
Another supported use case is as stream transformers.
new File(...).openRead().transform(new Crc32Zlib()).single.then(...)
Instead of using predefined classes, it is also possible to construct a
customized CRC function with
ParametricCrc class. For a list of known
CRC routines, check out http://reveng.sourceforge.net/crc-catalogue/all.htm.
