ai_sdk_openai_compatible 1.2.0

Shared OpenAI Chat Completions base for AI SDK Dart providers. Implements tool calling, multimodal content, structured output, and SSE streaming once, behind a small per-provider config.

1.2.0

First release (versioned 1.2.0 to align with the AI SDK Dart monorepo).

• OpenAICompatibleChatLanguageModel — a full LanguageModelV3 implementation of the OpenAI Chat Completions wire format: multimodal content parts (text + image + audio + file), tools / tool_choice (with strict), response_format JSON-schema, SSE streaming (text deltas + index-based tool-call delta state machine + finish + usage), non-streaming tool-call parsing, and finish-reason mapping.
• apiErrorFromDioException(...) — a shared Dio→AiApiCallError bridge (delegating to AiApiCallError.fromResponse) so non-2xx responses surface as a typed AiApiCallError on both the non-streaming and stream-setup paths. Imported by the OpenAI / Azure / Groq / Mistral providers.
• OpenAICompatibleConfig — a small config object parameterizing the per-provider quirks: auth header scheme, base URL, query parameters (e.g. Azure api-version), body field name overrides (seed vs random_seed, max_tokens vs max_completion_tokens), feature flags (supportsTools, supportsMultimodal, supportsResponseFormatJsonSchema), an extraBody hook for provider-specific fields, and a Dio factory.
