unnecessary_getters_setters

Unnecessary use of getter and setter to wrap a field.

The analyzer produces this diagnostic when a getter and setter pair returns and sets the value of a field without any additional processing.

The following code produces this diagnostic because the getter/setter pair named c only expose the field named _c:

class C {
  int? _c;

  int? get c => _c;

  set c(int? v) => _c = v;
}

Make the field public and remove the getter and setter:

class C {
  int? c;
}
