operator == method

  1. @override
bool operator ==(
  1. Object other
)

The equality operator.

The default behavior for all Objects is to return true if and only if this object and other are the same object.

Override this method to specify a different equality relation on a class. The overriding method must still be an equivalence relation. That is, it must be:

  • Total: It must return a boolean for all arguments. It should never throw.

  • Reflexive: For all objects o, o == o must be true.

  • Symmetric: For all objects o1 and o2, o1 == o2 and o2 == o1 must either both be true, or both be false.

  • Transitive: For all objects o1, o2, and o3, if o1 == o2 and o2 == o3 are true, then o1 == o3 must be true.

The method should also be consistent over time, so whether two objects are equal should only change if at least one of the objects was modified.

If a subclass overrides the equality operator, it should override the hashCode method as well to maintain consistency.

Implementation

@override
bool operator ==(Object other) {
  if (identical(this, other)) return true;
  if (other is! RoutePlace) return false;
  RoutePlace _other = other;
  return type == _other.type &&
      waypointIndex == _other.waypointIndex &&
      originalCoordinates == _other.originalCoordinates &&
      mapMatchedCoordinates == _other.mapMatchedCoordinates &&
      displayCoordinates == _other.displayCoordinates &&
      chargeInKilowattHours == _other.chargeInKilowattHours &&
      chargingStation == _other.chargingStation &&
      name == _other.name &&
      id == _other.id &&
      platform == _other.platform &&
      sideOfDestination == _other.sideOfDestination &&
      _indoorLocation == _other._indoorLocation;
