AVOID defining a one-member abstract class when a simple function will do.
Unlike Java, Dart has first-class functions, closures, and a nice light syntax
for using them. If all you need is something like a callback, just use a
function. If you're defining a class and it only has a single abstract member
with a meaningless name like call
or invoke
, there is a good chance
you just want a function.
GOOD:
typedef Predicate = bool Function(item);
BAD:
abstract class Predicate {
bool test(item);
}
