I see there is a double.INFINITY but I can't see a way to say "int INFINITY". Which is interesting, because I see I can do <code>some_integer.isInfinite</code>. What's a way to say <code>int.INFINITY</code> in Dart? Does that even make sense?

No. All Dart integers are finite. You can ask <code>42.isInfinite</code>, but the answer is predictably <code>false</code>. If you check the code of the <code>int</code> class, you'll like find <code>bool get isInfinite => false;</code> somewhere. The reason the getter is there at all is that it's defined on <code>num</code>, the superclass of <code>int</code> and <code>double</code>, and you can do many operation on numbers without knowing whether they are integers or doubles.

Is there an int.INFINITY for Dart?
