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) =>
    identical(this, other) ||
    other is LoggedInWatchingMyProfile &&
        runtimeType == other.runtimeType &&
        feedId == other.feedId &&
        app == other.app &&
        currentMemberProfileModel == other.currentMemberProfileModel &&
        currentMember == other.currentMember &&
        postAccessibleByGroup == other.postAccessibleByGroup &&
        ListEquality()
            .equals(postAccessibleByMembers, other.postAccessibleByMembers) &&
        uploadingBGProgress == other.uploadingBGProgress &&
        uploadingProfilePhotoProgress == other.uploadingProfilePhotoProgress;
