As part of their commitment to Kotlin and providing a first-class developer experience using the Jetpack series of libraries, Google announced DataStore at Google I/O this year. The DataStore library allows us to store either key-value pairs, or strongly typed objects, and is the recommended replacement for the legacy SharedPreferences Android API. According to Google,

DataStore uses Kotlin coroutines and Flow to store data asynchronously, consistently, and transactionally.

This repo is the companion to a WWT Platform article that focuses specifically on how to use and test the Preferences DataStore to store simple key-value pairs. If you need to store strongly typed, complex objects, consider using the protocol buffers-based Proto DataStore instead.
