Getter/Setter in Flutter using Android Studio

Question

I am making an app in Flutter and i am using Android studio for that. But it is not making getter and setter by using alt+insert command to generate getter and setter automatically.is there any way of doing this?

Answer 1

You don't need that in Dart.

A field is equivalent to a getter/setter pair. A final field is equivalent to a getter.

You change it only to actual getters/setters if additionally logic is required and this change is non-breaking for users of that class.

Public getter/setter methods for private fields is an anti-pattern in Dart if the getters/setters don't contain additional logic.

class Foo {
  String bar; // normal field (getter/setter)
  final String baz; // read-only (getter)

  int _weight;
  set weight(int value) {
    assert(weight >= 0);
    _weight = value;
  }
  int get weight => _weight
}

Answer 2

I didn't clearly understand your questions but check if this helps.

String _myValue = "Hello World";

Now press Comman+N in mac and select Getter and Setter.

Now that you can see the Getter and Setter generated for you.

String _myValue = "Hello World";

  String get myValue => _myValue;

  set myValue(String value) {
    _myValue = value;
  }

Ensure that you use "_" as a prefix for the private variables.

EDIT:

Noticing the higher votes for my answer, I'm responsible to clarify a few things here. As rightly mentioned by Günter Zöchbauer, explicit getter/setter declarations are not necessary for Dart.
