equals method
Compare two elements for being equal.
This should be a proper equality relation.
Implementation
@override
bool equals(List<E>? list1, List<E>? list2) {
if (identical(list1, list2)) {
return true;
}
if (list1 == null || list2 == null) {
return false;
}
final int length = list1.length;
if (length != list2.length) {
return false;
}
for (int i = 0; i < length; i++) {
if (!_elementEquality.equals(list1[i], list2[i])) {
return false;
}
}
return true;
}
