CharacterGroup class

Expression that contains a series of characters, or character ranges, that matches if any character of the input matches element(s) of the group. Can accept a caret (^) symbol as first element to apply a negated matching where it will instead match everything that is not within the group.

Example:

RegExp exp = FancyRegex(
  expression: const CharacterGroup(
    [
      CharacterGroupRange.upperCased(),
      CharacterGroupRange.digits(),
    ],
  ),
);
print(exp.pattern,); // [A-Z0-9]
final matches = exp.allMatches("FooBar123",);
