featureflip 2.0.0

Flutter SDK for Featureflip — evaluate feature flags in Flutter apps with real-time updates.

2.0.0

BREAKING: Singleton-by-construction refactor.

• Removed public constructor FeatureflipClient(config:), FeatureflipClient.withHttpClient(), FeatureflipClient.configure(), and FeatureflipClient.shared.
• Added FeatureflipClient.get(sdkKey, config:) static factory — the only way to obtain a client. Multiple calls with the same SDK key return handles sharing one refcounted core.
• Added FeatureflipClient.resetForTesting() for test isolation.
• FeatureflipClient.forTesting() unchanged — continues to create independent test clients.

Migration

Before:

final client = FeatureflipClient(config: config);
// or
FeatureflipClient.configure(config);
final client = FeatureflipClient.shared;

After:

final client = FeatureflipClient.get('your-sdk-key', config: config);
