Оба присылайте самый долбанутый код, который сможете написать
import 'dart:core' if (dart.library.html) 'dart:core' as core
show dynamic, print
hide String, bool, int, double, num;
void main() => await
.$(({required final Type $}) =>
'brain' | (v) => '$v fuck: ' | (v) => sync(v + (!($())!).toString()))
.abstract()()($: () => _.$!());
typedef Type = core.dynamic;
typedef hide = void Function({required Type $});
final sync = core.print;
abstract class async {
final hide typedef;
const async._({required final hide operator}) : typedef = operator;
const factory async(final typedef) = yield.$;
void Function({required Type $}) call() => typedef;
}
class yield extends async {
const yield.$(final typedef) : super._(operator: typedef);
}
mixin on on async {
async abstract() => yield.$(typedef);
}
class await = yield with on;
abstract class _ {
static Type? get $ => () => $$ = $$ = $$ = $$ = $$;
static late Type? $$ = true;
}
extension on Type {
Type operator |(final Type show) => show(this);
}
