| * The hash code for this object. |
| * A hash code is a single integer which represents the state of the object that |
| * affects == comparisons. |
| * All objects have hash codes. The default hash code represents only the |
| * identity of the object, the same way as the default == implementation only |
| * considers objects equal if they are identical (see identityHashCode). |
| * @description Checks that [hashCode] is read-only and can't be set. |
