bullseye

Bullseye is a new flavour of regex for Dart, because JavaScript's regex flavour sucks quite a lot.

Some things Bullseye has that JS regex doesn't:

Lookbehinds (positive and negative)
Variable-length lookaheads

Possible features:

Named capturing groups
Backtracking
Recursion (probably not)

Usage

A simple usage example:

import 'package:bullseye/bullseye.dart';

void main() {
  NewRegex dart = new NewRegex("ab*");

  print(dart.allMatches("ababbaa")); // => ["ab", "abb", "a", "a"]
}
