Sort unnamed constructor declarations first.

This rule is available as of Dart 2.0.0.

This rule has a quick fix available.

Details

DO sort unnamed constructor declarations first, before named ones.

BAD:

class _PriorityItem {
  factory _PriorityItem.forName(bool isStatic, String name, _MemberKind kind) => ...
  _PriorityItem(this.isStatic, this.kind, this.isPrivate);
  ...
}

GOOD:

abstract class CancelableFuture<T> implements Future<T>  {
  factory CancelableFuture(computation()) => ...
  factory CancelableFuture.delayed(Duration duration, [computation()]) => ...
  ...
}

Usage

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

linter:
  rules:
    - sort_unnamed_constructors_first
