flutter is here
LOL, this was posted 8 years ago, and everyone is just now commenting probably because of Flutter!
haha True !!
Thanks
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!!!!!!!
