Overview
LangChain.dart is a Dart and Flutter package that enables developers to build powerful applications leveraging Large Language Models (LLMs). It provides a structured framework for integrating LLMs into Flutter apps, supporting tasks like natural language processing, text generation, and conversational AI. With support across all major platforms—Android, iOS, Web, macOS, Windows, and Linux—it allows seamless deployment of AI-powered features in mobile and desktop environments. The package simplifies workflows by offering tools for prompt management, chain composition, and model integration, making it easier to prototype and scale generative AI applications within the Flutter ecosystem.
