The dartantic_chat package provides the widgets to make it easy to add an AI chat window to your Flutter app. The package is organized around an abstract chat history provider API that makes it easy to swap out the agentic SDK or REST endpoint that you’d like your chat widget to use. Out of the box, it comes with support for dartantic_ai, which provides access to multiple LLM providers including Google Gemini, OpenAI, Anthropic, Mistral, and Ollama. Dartantic Chat Screenshot
