Re-reselect for Dart

A Selector library for Dart, based on the original Re-reselect JavaScript library.

Motivation

re-reselect is a lightweight wrapper around Reselect meant to enhance selectors with deeper memoization and cache management.

Switching between different arguments using standard reselect selectors causes cache invalidation since default reselect cache has a limit of one.

re-reselect forwards different calls to different reselect selectors stored in cache, so that computed/memoized values are retained.

re-reselect selectors work as normal reselect selectors but they are able to determine when creating a new selector or querying a cached one on the fly, depending on the supplied arguments.

Useful to:

• Retain selector's cache when sequentially called with one/few different arguments
• Join similar selectors into one
• Share selectors with props across multiple component instances
• Instantiate selectors on runtime
• Enhance reselect with custom caching strategies

See example and tests for details.
