How to copy List in dart without old reference?

Question

Code will explain all:

//modal for list
class MyModal
{
 int myField1;
 List adjacentNodes;
 MyModal(this.myField1)
 {
  adjacentNodes= new Lis         


        

Answer 1

you can use List.from() function. try this code:

//modal for list
class MyModal {
  int myField1;
  String name;
  List adjacentNodes;
  MyModal(this.myField1, this.name) {
    adjacentNodes = new List();
  }
}

void runCopy() {
//pre code
  List originalList = new List();
  originalList.add(new MyModal(1, "firstBuddy"));

//copying list
  List secondList = List.from(originalList);
  secondList.addAll(originalList);
  print(originalList);
  print(secondList);
}
