# isSupersetOf method

bool isSupersetOf(

1. Set<Object?> other

)

Utility extension methods for working with sets in Dart.

Provides helpful methods for checking subset and superset relationships between sets, particularly when working with sets of nullable objects.

Example:

    final a = {1, 2};
    final b = {1, 2, 3};
    print(a.isSubsetOf(b)); // true
    print(b.isSupersetOf(a)); // true

Returns `true` if this set is a superset of `other`, meaning it contains all elements of `other`. Internally delegates to isSubsetOf.

Example:

    final a = {1, 2, 3};
    final b = {2};
    print(a.isSupersetOf(b)); // true

## Implementation

    bool isSupersetOf(Set<Object?> other) {
      return other.isSubsetOf(this);
    }
