Overview
Localstorage is a Flutter package providing persistent key-value storage, serving as an alternative to React Native's AsyncStorage. It enables storing and retrieving data across app restarts on multiple platforms including Android, iOS, Web, macOS, Windows, and Linux. Built with simplicity in mind, it offers asynchronous operations for reading and writing strings, numbers, and JSON-serializable objects. The package abstracts platform-specific storage mechanisms, ensuring consistent behavior across environments. Ideal for caching, user preferences, or small-scale data persistence without requiring a full database.
