- Add com.apple.security.network.client to the macOS entitlements so sandboxed builds can reach LaunchDarkly. - Declare the INTERNET permission in the main Android manifest so release builds (which merge only that manifest) have network access. - Only update the displayed active context when identify completes; a superseded or errored identify no longer relabels the context.

Stacked on #314 (the Flutter FDv2 exposure). A runnable example app demonstrating FDv2 in the Flutter SDK.
What it shows
LDConfig(..., dataSystem: DataSystemConfig()).LDClient.setConnectionMode(...).Registered in the melos workspace (
packages/flutter_client_sdk/example_fdv2). Modeled on js-core's react-nativeexample-fdv2.flutter analyzeclean on the examplelib/.Note
Low Risk
Example-only and documentation; no changes to the published SDK library code paths.
Overview
Adds
packages/flutter_client_sdk/example_fdv2, a runnable manual-test app for the Flutter SDK’s FDv2 data path, and registers it inmelos.yamlsomelos bootstraplinks the local SDK.The demo UI wires
LDConfigwithdataSystem: DataSystemConfig()(FDv2 opt-in),CredentialSource.fromEnvironment(), and a sample user context. It surfaces livedataSourceStatusChanges,flagChanges/allFlags(), runtimesetConnectionMode(automatic, streaming, polling, background, offline), andidentifywith result feedback. A README documents credentials via--dart-defineand expected manual checks.Platform scaffolding (Android/iOS/web/desktop) is standard Flutter template output; the meaningful product change is the example app plus melos membership, not SDK internals.
