llm_sdk 0.5.0

Unified interface for talking to LLMs (Claude, OpenAI, Gemini) from Dart/Flutter: multi-provider, streaming, tool calling, structured outputs.

0.5.0

• Sampling options: new GenerationOptions (temperature, topP, stopSequences) accepted by every LlmClient method (generate, generateText, streamText, streamEvents, generateObject) and mapped by each adapter to its own dialect (temperature/top_p/stop on OpenAI, stop_sequences on Claude, generationConfig on Gemini). A null field is omitted, so the model's default applies.
• Network resilience: new RetryPolicy (configurable per provider via the retry: constructor argument). The generate path now retries transient failures — HTTP 408/429/5xx, timeouts, and dropped connections — with exponential backoff, and every request is bounded by a timeout. Streaming applies the connection timeout only (replaying a started stream is unsafe). RetryPolicy.none opts out.
• +12 tests (42 total): options mapping per provider, backoff timing, retry / exhaustion / non-retryable-status / network-drop / timeout, and client-level options passthrough. No breaking change: the new parameters are optional.

0.4.0

• Local models via OpenAIProvider: apiKey is now optional (defaults to empty) and the Authorization header is omitted when empty, for self-hosted OpenAI-compatible servers (Ollama, LM Studio, llama.cpp, vLLM). baseUrl was already overridable — no other API change.
• Added example/ollama_example.dart (fully local streaming + tool calling).
• README: new "Local models" section.

0.3.1

• README: demo GIFs ("switch provider = 1 line", word-by-word streaming).
• pubspec: screenshots: (shown on pub.dev).
• No code or API change.

0.3.0

• GeminiProvider adapter (Generative Language generateContent API): assistant role → model, system_instruction, tool results re-attached by name as functionResponse (Gemini has no call ID — we map ToolCallPart.id == name), forcing via tool_config mode ANY, SSE streaming (streamGenerateContent?alt=sse), usage and finishReason. API key in the x-goog-api-key header, configurable baseUrl.
• +7 Gemini tests (29 total). No change to the core: all 3 providers share the same abstraction.

0.2.0

• OpenAIProvider adapter (Chat Completions API): encoding/decoding, tool calling (tool_calls + JSON-string arguments), structured outputs via forced tool, SSE streaming (assembling tool calls by index), usage and finishReason. Configurable baseUrl (compatible with OpenAI-like endpoints). No change to the core: the abstraction holds as-is.
• +8 OpenAI tests (22 total).

0.1.0

First slice: provider-agnostic core + complete Claude adapter.

• Core: types (Message/Part/Tool/LlmResponse/LlmStreamEvent), LlmProvider contract (generate + generateStream), LlmClient carrying the tool loop, streamText, generateText and generateObject<T>.
• ClaudeProvider adapter (Anthropic Messages API): encoding/decoding, tool calling, structured outputs via forced tool, SSE streaming (TextDelta / ToolCallDelta / StreamDone), usage and finishReason.
• 20 tests (client logic on a mocked provider + Claude round-trip/SSE).
