expire_cache

A dart package provides a generic cache that will expire according to time.

If you want to implement SearchDelegate in your app, you will have to cache your search results if you don't want to call your search backend for multiple times on the same query.

See:

Because this is related to search, it is valuable to expire the cache after a preiod of time, to give user fresh search result. And this is the goal for this package, to develop an expire by fix time cache.
