sort_constructors_first

Sort constructor declarations before other members.

This rule is available as of Dart 2.0.

This rule has a quick fix available.

DO sort constructor declarations before other members.

BAD:

abstract class Visitor {
  double value;
  visitSomething(Something s);
  Visitor();
}

GOOD:

abstract class Animation<T> {
  const Animation(this.value);
  double value;
  void addListener(VoidCallback listener);
}

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

linter:
  rules:
    - sort_constructors_first
