A quiver:Cache implementation backed by


Cache<K,V> myCache = new StorageCache('my-prefix');


myCache.get('favoriteColor').then((item) => print(item));
#=> 'green'

myCache.get('spoon', ifAbsent: (key) => 'There is no $key.');
#=> 'There is no spoon.'

myCache.get('spoon').then((item) => print(item));
#=> 'There is no spoon.'


  • This is a work in progress. Proceed with caution.
  • This has only been tested on Chrome Apps, not Chrome Extensions.
  • You must supply a prefix to the StorageCache constructor.
  • This only works for objects that can be serailzed via the Chrome Storage API. See below for more information.

Object serialization

From the Chrome App JavaScript API docs:

Primitive values such as numbers will serialize as expected. Values with a typeof "object" and "function" will typically serialize to {}, with the exception of Array (serializes as expected), Date, and Regex (serialize using their String representation).

The behavior under Dart is identical.
