From the style guide:

PREFER using a public final field instead of a private field with a public getter.

If you have a field that outside code should be able to see but not assign to (and you don't need to set it outside of the constructor), a simple solution that works in many cases is to just mark it final.


class Box {
  final contents = [];


class Box {
  var _contents;
  get contents => _contents;
