w_common 1.9.0

w_common #

A collection of helpful utilities for use in Dart projects. Right now, it includes the following:

  • Disposable interface / mixin to assist with cleaning up streams and other data structures that won't necessarily be garbage collected without some manual intervention.
  • A simple typedef that can be parameterized to represent a zero-arity callback that returns a particular type.
  • InvalidationMixin mixin used to mark a class as requiring validation.
  • JsonSerializable interface to indicate that something can be serialized to JSON.

We expect this list to grow as we identify small pieces of code that are useful across a wide variety of Dart projects, especially in cases where there is value in projects sharing a single implementation.

The package version is not analyzed, because it does not support Dart 2. Until this is resolved, the package will receive a health and maintenance score of 0.

Analysis issues and suggestions

Support Dart 2 in pubspec.yaml.

The SDK constraint in pubspec.yaml doesn't allow the Dart 2.0.0 release. For information about upgrading it to be Dart 2 compatible, please see https://dart.dev/dart-2#migration.

Maintenance issues and suggestions

Make sure dartdoc successfully runs on your package's source files. (-10 points)
