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

I was having the same problem, List.from() and List.of() didn't work. I had to map the current list, thus creating a new instance.

List<CompanyBranchesDTO> get companyBranchesCopy {
  return companyBranches.map((e) =>
          CompanyBranchesDTO(id: e.id, name: e.name, isChecked: e.isChecked))
      .toList();
}

That way I have a new instance to inject where it is needed.
