shared_preferences_watchos #

The watchOS implementation of shared_preferences.

Scaffolded with flutter-watchos plugin port and finished by hand as an FFI implementation over NSUserDefaults — see PORTING_REPORT.md.

Usage #

dependencies:
  shared_preferences: ^2.3.0
  shared_preferences_watchos: ^0.1.0

Both the classic SharedPreferences API and the newer SharedPreferencesAsync API work on the watch — no imports needed in app code.

How it works #

The store is a single JSON object persisted in NSUserDefaults under one private key. The native side only loads and saves that blob; all typing and filtering is done in Dart, so the five supported value types (bool, int, double, String, List<String>) round-trip exactly. Both the legacy SharedPreferencesStorePlatform and the async SharedPreferencesAsyncPlatform are registered against the same store, mirroring shared_preferences_foundation.
