doCompare method Null safety

int doCompare(

The implementation of compareTo.

The argument is guaranteed to be of the same type as this object and have the same name.

The method should return a negative number if this object comes earlier in the sort order than the argument; and a positive number if it comes later in the sort order. Returning zero causes the system to use default sort order.

Implementation

int doCompare(covariant SemanticsSortKey other);
