How can I spread a List in Dart?

Question

Is there any way to unpack a list in dart? I want to do something similar to this python snippet:

return proc(*args)

Answer 1

Dart does not support unpacking a List into function arguments.

However, you can unpack a List into another List by typing three dots ... before the list name.

List<int> oneTwo = [1, 2];
List<int> oneTwoThree = [...oneTwo, 3];

print(oneTwoThree); // [1, 2, 3]
