 The library provides ways to define equalities on `Iterable`s, `List`s, `Set`s,
 and `Map`s, as well as combinations of these, such as:
 
-    const MapEquality(const IdentityEquality(), const ListEquality());
+```dart
+const MapEquality(const IdentityEquality(), const ListEquality());

 This equality considers maps equal if they have identical keys, and the
 corresponding values are lists with equal (`operator==`) values.
