Dart forEach() on a List/Set

foreachlistset.dart

main() {
    List<String> list = new List<String>();
    list.add('one');
    list.add('two');
    list.add('twelve');
    list.forEach((element) => print(element));

    Set<String> set = Set.from(list);
    set.forEach((element) => print(element));    
}

Thanks, I don't even know dart was this old.

LOL, this was posted 8 years ago, and everyone is just now commenting probably because of Flutter!

haha True !!

Still Commenting!

Hey, what if we want to execute a block of comments using forEach? Would the following be valid?

list.forEach( (item) {
//do something
//do something else
});

@fourpointfour
list.forEach((item) => print(item)); is nothing else then list.forEach((item) { return print(item);});
since the return type is void, you are not using the return type anyways. So your syntax is totally valid.

cool

You can use set.forEach(print) instead of set.forEach((element) => print(element))

Great!

Awesome!

We still use it in 2021, thanks man!

i think we should avoid using set for variable name

BIG thanks

ありがとうございます！！！！！！！

COOL

Nice, thanks a lot!
