dartantic_interface 3.0.0

Interface definitions for dartantic_ai for use in building custom providers.

Welcome to dartantic_interface!

This repo contains the implementation for the dartantic_interface package. It forms the base set of interfaces used to implement providers and chat and embeddings models for dartantic_ai.

By implementing a custom provider based on dartantic_interface, you do not need to depend on all of dartantic_ai. Likewise, your provider does not need to be multi-platform or support wasm, as is the requirement for providers built into dartantic_ai.

Core Types

This package re-exports core message and part types from genai_primitives:

• ChatMessage, ChatMessageRole - Conversation messages
• Part, TextPart, DataPart, LinkPart, ThinkingPart - Message content
• ToolPart, ToolPartKind - Tool calls and results
• ToolDefinition - Tool schema definitions

Schema construction is provided by json_schema_builder. Use the S builder class:

import 'package:dartantic_interface/dartantic_interface.dart';

final schema = S.object(properties: {
  'name': S.string(description: 'User name'),
  'age': S.integer(minimum: 0),
});
