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.
• A CSS compilation executable that can be run via

  pub run w_common:compile_sass
  

  from the root of your package that depends on w_common.
  • It can also be used as a watcher - great for when you're doing a lot of work on .scss files and don't want to have to remember to keep re-running the script after each change.

    pub run w_common:compile_sass --watch
    

  • Run

    pub run w_common:compile_sass -h
    

    for more usage details / instructions.

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.
