A Flutter plugin that enables simple persistent storage of key-value pairs across platforms. It abstracts native APIs—NSUserDefaults on iOS and SharedPreferences on Android—providing a unified interface for storing basic data like user preferences, settings, or session tokens. The package supports all major platforms including Web, macOS, Windows, and Linux, making it ideal for lightweight, cross-platform data persistence. Data is stored locally and accessed asynchronously, ensuring performance and reliability in typical app scenarios.
