flagnetic 0.1.2

Feature flags and experiments for Dart and Flutter apps. Client mode with a client key; values are cached on the device and served offline.

example/main.dart

// A client that serves a flag from the values remote evaluation returned
// for its context, records an exposure and closes. In a Flutter app,
// flagnetic_flutter adds widgets, the app lifecycle and a store.

    options: const ClientOptions(platform: 'android', appVersion: '1.42.0'),
  );

  // Getters are synchronous and never throw: until the values arrive, the
  // built-in default given here is served.
