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

Then:

var newMyList = myList1 + myList2;

Is valid :)

Answer 2

No need to create a third list in my opinion...

Use this:

list1 = [1, 2, 3];
list2 = [4, 5, 6];
list1.addAll(list2);

print(list1); 
// [1, 2, 3, 4, 5, 6] // is our final result!
