Using Shared Preferences in Flutter to cache mission-critical payloads

Using Shared Preferences in Flutter to cache payloads

Caching significantly improves speed and performance in any application. Ever wondered why Redis is so fast? All the data is stored in memory cache. RAM I/O is significantly faster than any other I/O (disk or network).

By leveraging memory and/or disk caching, you'll be able to avoid making additional network requests and improve your apps' performance.
