dartnative_shared_preferences

Simple key–value preferences for DartNative — NSUserDefaults on iOS, SharedPreferences on Android — with the familiar shared_preferences API. iOS and Android.

Why you'll like it

• Familiar API — getInstance(), then getString / setBool / …, like shared_preferences.
• All the common types — String, int, double, bool, List<String>.
• Works from any isolate — no platform channel, so reads and writes work outside the main isolate.
• Zero setup — backed by the platform's native defaults via the DartNative framework.

Highlights

• SharedPreferences.getInstance() → the store.
• getString / getInt / getDouble / getBool / getStringList (+ containsKey).
• setString / setInt / setDouble / setBool / setStringList, plus remove / clear / reload.

getKeys() (enumerate all keys) isn't available yet.
