doCompare method
- covariant NumericFocusOrder other
override
The subclass implementation called by compareTo to compare orders.
The argument is guaranteed to be of the same runtimeType as this object.
The method should return a negative number if this object comes earlier in
the sort order than the other argument; and a positive number if it
comes later in the sort order than other. Returning zero causes the
system to fall back to the secondary sort order defined by
OrderedTraversalPolicy.secondary
Implementation
@override
int doCompare(NumericFocusOrder other) => order.compareTo(other.order);
