equals method

@override bool equals(dynamic e1, dynamic e2)

Compare two elements for being equal.

This should be a proper equality relation.

Implementation

@override
bool equals(e1, e2) {
  if (e1 is Set) {
    return e2 is Set && SetEquality(this).equals(e1, e2);
  }
  if (e1 is Map) {
    return e2 is Map && MapEquality(keys: this, values: this).equals(e1, e2);
  }

  if (e1 is List) {
    return e2 is List && ListEquality(this).equals(e1, e2);
  }
  if (e1 is Iterable) {
    return e2 is Iterable && IterableEquality(this).equals(e1, e2);
  }

  return _base.equals(e1, e2);
}
