Private Setters in Dart

Question

I have been looking but couldn't find any reference to this. I would like to create a private setter in Dart to call an additional function after I have changed a private variable.

ViewState _state;

ViewState get state => _state;

set _state(value) {
  _state = value;
  notifyListeners();
}

How Can I achieve this?

Dart is no allowing private setters, it's true. You can hack it with your own private function

ViewState _state;

ViewState get state => _state;

void _changeState(value) {
  _state = value;
  notifyListeners();
}

here my sample on DartPad where you can make some experiments.
