how to sort list and return using Flutter and Dart

Question

I am new to development. I am having issue with existing code I code from my fellow developer. They guy sorted a list using a model and compare the version but it only returns one element of the list. This is my code

static NavigationalCatalogDto getLatestVersionCatalog(
    List<NavigationalCatalogDto> navigationalCatalogList) {
      navigationalCatalogList.sort((b, a) => a.version!.compareTo(b.version!));
      return navigationalCatalogList[0];
    }

I want to return all the items inside the list after sorting. please help me

You can simply remove the [0] so it does not select the first element. Remember to change the return type of the method as well.

static List<NavigationalCatalogDto> getLatestVersionCatalog(
List<NavigationalCatalogDto> navigationalCatalogList) {
  return navigationalCatalogList.sort((b, a) => a.version!.compareTo(b.version!));
}
