anagram method
Get all legal anagrams of a string, perhaps includng the wildcard '?'.
If expand
is true then wildcards are expanded.
If sort
is true then results are sorted into alphabetical order.
If minLength
is >2 then only matches of at least that length are returned.
Implementation
Set<String> anagram(String word,
{bool expand = false, bool sort = false, int minLength = 2}) {
var anagrams = <String>{};
_anagramWord(anagrams, '', word, expand, minLength);
if (sort) {
return SplayTreeSet.from(anagrams);
}
return anagrams;
}
