# operator + method

List<E> operator + (List<E> other)

Returns the concatenation of this list and `other`.

Returns a new list containing the elements of this list followed by the elements of `other`.

The default behavior is to return a normal growable list. Some list types may choose to return a list of the same type as themselves (see Uint8List.+);

## Implementation

    List<E> operator +(List<E> other) {
      var result = <E>[]..length = (this.length + other.length);
      result.setRange(0, this.length, this);
      result.setRange(this.length, result.length, other);
      return result;
    }
