Overview
The state_persistence package enables persistent storage of application state across app launches in Flutter. It automatically saves state to a local JSON file named `data.json` in the app's data directory, ensuring data survives restarts and device reboots. The library is designed for simplicity, offering an easy-to-use API that integrates seamlessly with state management solutions. It supports multiple platforms including Android, iOS, macOS, Windows, and Linux, making it ideal for cross-platform apps requiring reliable state retention.
