How do I combine two lists in Dart?

Question

I was wondering if there was an easy way to concatenate two lists in dart to create a brand new list object. I couldn\'t find anything and something like this:

My list:

Answer 1

Alexandres' answer is the best but if you wanted to use + like in your example you can use Darts operator overloading:

class MyList{
  List _internal = new List();
  operator +(other) => new List.from(_internal)..addAll(other);
  noSuchMethod(inv){
    //pass all calls to _internal
  }
}

Then:

var newMyList = myList1 + myList2;

Is valid :)
