operator == method

@override bool operator ==(Object other)

Equality.

• If T is Iterable uses IterableEquality.equals.

Implementation

@override
bool operator ==(Object other) {
  if (identical(this, other)) return true;

  if (other is! Pair) return false;

  var a = this.a;

  if (a is Iterable) {
    var b = this.b as Iterable;
    return _iterableEquality.equals(a, other.a) &&
        _iterableEquality.equals(b, other.b);
  } else {
    return a == other.a && b == other.b;
  }
}
