feat_openfeature 0.1.0

OpenFeature provider for feat. Wraps the feat Dart SDK to expose feat through the OpenFeature API.

example/feat_openfeature_example.dart

// Example: read a feat flag through the OpenFeature server API.
//
// Run from the package root with:
//   dart run example/feat_openfeature_example.dart
//
// Replace the apiKey with a real feat client-side id (prefix `feat_cs_`) or a
// mobile key. Never use a server key in a client SDK.
import 'package:feat_openfeature/feat_openfeature.dart';
import 'package:feat_sdk/feat_sdk.dart';
import 'package:openfeature_dart_server_sdk/open_feature_api.dart';

Future<void> main() async {
  // 1. Construct and initialize the feat client.
  final featClient = await FeatClient.initialize(
    FeatClientConfig(
      apiKey: 'feat_cs_replace_me',
      // baseUrl defaults to https://data-01.feat.so
      context: EvalContext.user('user-123', attributes: {'plan': 'pro'}),
    ),
  );

  // 2. Register the provider with OpenFeature and wait for it to be ready.
  final provider = FeatProvider(featClient);
  final api = OpenFeatureAPI();
  await api.setProviderAndWait(provider);

  // 3. Read flags through the standard OpenFeature client.
  final client = api.getClient('example');

  final checkoutV2 =
      await client.getBooleanFlag('checkout-v2', defaultValue: false);
  print('checkout-v2 = $checkoutV2');

  final theme = await client.getStringFlag('theme', defaultValue: 'light');
  print('theme = $theme');

  // 4. Change context: set it on the provider (or the feat client) rather than
  //    via the per-evaluation context argument. This re-polls feat and
  //    refreshes the synchronous cache.
  await provider.setContext(EvalContext.user('user-456'));

  // 5. Tear down.
  await api.shutdownProvider();
