Hive

// Hive is a key-value store that lives
// right on the device.
//
// Boxes are typed collections. Open one
// by name, read and write values, and
// subscribe to changes.
//
// Reach for Hive for: settings, drafts,
// caches, queued offline writes, anything
// that should survive a cold launch.
//
// Reach for sqflite or drift if you need
// real SQL. shared_preferences for tiny
// key/values. flutter_secure_storage for
// tokens and secrets.
