Diff Match Patch
This is a port of google-diff-match-patch library to Dart. Initially maintained by localvoid, handed off to jheyne for upgrades.
This library implements Myer's diff algorithm which is generally considered to be the best general-purpose diff. A layer of pre-diff speedups and post-diff cleanups surround the diff algorithm, improving both performance and output quality.
This library also implements a Bitap matching algorithm at the heart of a flexible matching and patching strategy.
