First forkbomb in dart lang

Question

Let‘s golf it to the max!

So I wondered why there is no forkbomb on the web for dart... so I created one. I started to golf it to:

Dart, 98 bytes

import'dart:isolate';class f{static k(o){f().r();}r(){for(;;)Isolate.spawn(k,0);}}main(){f().r();}

Try it online!

Any suggestions or golfing even further wins.

Answer 2

90 86 bytes

I don't know Dart too well, but you can save some bytes by using the Constructor of class f instead of the method r. This allows you to get rid of the f().r() inside the static method k(o), as well as the .r() after the f() in the main method:

import'dart:isolate';class f{static k(o){}f(){for(;;)Isolate.spawn(k,0);}}main(){f();}
