flutter_native_ai 0.5.0

A Flutter plugin for native on-device generative AI through Apple Foundation Models and Android Gemini Nano.

0.5.0

• Introduces a typed exception hierarchy (OnDeviceAiException and subclasses) so consumers can catch specific error types instead of raw PlatformException. All errors from the service layer now surface as one of: OnDeviceAiUnsupportedException, OnDeviceAiUnavailableException, OnDeviceAiSessionNotFoundException, OnDeviceAiGenerationFailedException, or OnDeviceAiSessionDisposedException.

0.4.1

• Fixes podspec s.version to match pubspec.yaml version (was frozen at 0.1.1).
• Fixes spurious stream cancellation on natural completion: onCancel now skips cancelStreamingText when the stream is already closing.
• Fixes Android ensureReady to emit a status event on all early-return paths, matching Apple behaviour.
• Fixes Android generation to share a single ML Kit client across non-streaming and streaming paths instead of creating a duplicate client.

0.4.0

• Replaces availability() with status() and OnDeviceAiStatus, separating platform support, model readiness, initialization capability, and raw native diagnostics.
• Adds ensureReady() for explicit model initialization/download flows.
• Adds OnDeviceAiInitializationPolicy and opt-in just-in-time initialization through createSession(initializationPolicy: ...).
• Adds statusStream() for model initialization status updates, including real 0..100 Android download progress when ML Kit supplies enough byte data.
• Adds Android Gemini Nano model download support through ML Kit GenerativeModel.download().

0.3.0

• Replaces service-level initialization and generation with explicit OnDeviceAiSession creation.
• Adds session-scoped non-streaming generation, streaming generation, cancellation, and disposal.
• Documents that only one streaming generation should be active at a time for a plugin instance.
• Reuses native Apple Foundation Models sessions across prompts in the same Dart session.
• Keeps per-session Android instructions and prompt history for Gemini Nano requests.

0.2.0

• Adds macOS plugin registration and an example macOS runner.
• Reuses the Apple Foundation Models bridge on macOS with runtime availability checks for macOS 26.0 or later.
• Adds Swift Package Manager support for the shared iOS/macOS implementation.
• Uses Swift Package Manager for both Apple example runners, including removing CocoaPods integration from the macOS runner.

0.1.1

iOS hotfix release.

• Fixes the Swift Package Manager library product name to match Flutter's generated hyphenated plugin product reference.

0.1.0

Initial pre-release

• Added an automated publish workflow

0.1.0-alpha.1

Initial alpha release.

• Adds a Dart API for on-device text generation availability, initialization, single response generation, streaming generation, and cancellation.
• Adds an iOS bridge for Apple Foundation Models.
• Adds an Android bridge for Gemini Nano through ML Kit Prompt API.
• Adds Pigeon-generated Dart, Swift, and Kotlin bindings.
