isEqualsSetDeep function
Same as isEqualsListDeep but for Set.
Implementation
bool isEqualsSetDeep(Set? set1, Set? set2, {ValueEquality? valueEquality}) {
if (identical(set1, set2)) return true;
if (set1 == null || set2 == null) return false;
var length = set1.length;
if (length != set2.length) return false;
var l1 = set1.toList();
var l2 = set2.toList();
l1.sort();
l2.sort();
return isEqualsListDeep(l1, l2, valueEquality: valueEquality);
}
