class_members_ordering

Details

DO arrange class members in a consistent order.

Class members should be ordered in the following sequence:

1. Public static fields
2. Private static fields
3. Public instance fields
4. Private instance fields
5. Public constructors
6. Public named constructors
7. Private constructors
8. Private named constructors
9. Public getters
10. Private getters
11. Public setters
12. Private setters
13. Public static methods
14. Public instance methods
15. Private static methods
16. Private instance methods

For widgets, the order is slightly different:

1. Public constructors
2. Public named constructors
3. Private constructors
4. Private named constructors
5. Public static fields
6. Private static fields
7. Public instance fields
8. Private instance fields
9. Public getters
10. Private getters
11. Public setters
12. Private setters
13. Public static methods
14. Public instance methods
15. Private static methods
16. Private instance methods

class A {
  void method() {}

  int field;

  A();
}

class AWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return const Placeholder();
  }

  final String field;

  const AWidget({
    super.key,
    required this.field,
  });
}

class A {
  int field;

  A();

  void method() {}
}

class AWidget extends StatelessWidget {
  const AWidget({
    super.key,
    required this.field,
  });

  final String field;

  @override
  Widget build(BuildContext context) {
    return const Placeholder();
  }
}

Usage

To enable the class_members_ordering rule, add class_members_ordering under custom_lint > rules in your analysis_options.yaml file:

custom_lint:
  rules:
    - class_members_ordering
