flutter_ai_sdk 1.2.0

A unified wrapper for AI APIs (OpenAI, Anthropic, Google AI, Ollama) with streaming, tool calling, context management, and multimodal support.

Changelog

All notable changes to Flutter AI SDK are documented here.

1.2.0 - 2026-07-07

Architecture overhaul & new features

• Architecture: full restructuring into one-class-per-file modules — config/, models/content/ (sealed hierarchy as part files), models/tools/; one folder per provider with a dedicated wire-format mapper; shared streaming loop in BaseProvider (template method); new ProviderRegistry factory supporting custom provider registration. The public API is unchanged.
• Tool Runner: automatic agentic tool-calling loop (ToolRunner, ExecutableTool) — parallel tool execution, error feedback to the model, iteration budget, observability callbacks.
• Ollama provider: run local models (Llama, Qwen, Gemma...) with streaming (NDJSON), tools, JSON mode and vision; no API key required.
• Anthropic: consecutive same-role messages are merged, as required by the API's role alternation (fixes parallel tool results).
• Dependencies upgraded for Flutter 3.44.

1.1.0 - 2026-07-06

Model refresh

• Default models updated to current generations: gpt-5.5, claude-opus-4-8, gemini-3.5-flash.
• Model context limits updated (GPT-5.x, Claude 4/5, Gemini 3.x).
• Anthropic provider: never sends temperature and top_p together (rejected by Claude 4+); maps the refusal and model_context_window_exceeded stop reasons.
• Providers can receive an injected HTTP client; FlutterAI accepts a custom provider. Unit tests for all providers and a CI workflow added.
• Dependencies upgraded (mime 2.x, rxdart 0.28, flutter_lints 6).

1.0.0 - 2025-11-30

Initial release

• Unified API for OpenAI, Anthropic and Google AI.
• Streaming with chunk events, context management and memory.
• Multimodal content (text, images, audio, documents).
• Function calling for all providers, typed error handling, token estimation.
