LLM-powered Dart\u002FFlutter applications.\n\n## What is LangChain.dart?\n\nLangChain.dart is an unofficial Dart port of the popular [LangChain](https:\u002F\u002Fgithub.com\u002Fhwchase17\u002Flangchain) Python framework created by [Harrison Chase](https:\u002F\u002Fwww.linkedin.com\u002Fin\u002Fharrison-chase-961287118).\n\nLangChain provides a set of ready-to-use components for working with language models and a standard interface for chaining them together to formulate more advanced use cases (e.g. chatbots, Q&A with RAG, agents, summarization, translation, extraction, recsys, etc.).\n\nThe components can be grouped into a few core modules:\n\n![LangChain.dart](https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdavidmigloz_langchain_dart_readme_16f6fc4fa5bf.png)\n\n- 📃 **Model I\u002FO:** LangChain offers a unified API for interacting with various LLM providers (e.g. OpenAI, Google, Mistral, Ollama, etc.), allowing developers to switch between them with ease. Additionally, it provides tools for managing model inputs (prompt templates and example selectors) and parsing the resulting model outputs (output parsers).\n- 📚 **Retrieval:** assists in loading user data (via document loaders), transforming it (with text splitters), extracting its meaning (using embedding models), storing (in vector stores) and retrieving it (through retrievers) so that it can be used to ground the model's responses (i.e. Retrieval-Augmented Generation or RAG). \n- 🤖 **Agents:** \"bots\" that leverage LLMs to make informed decisions about which available tools (such as web search, calculators, database lookup, etc.) to use to accomplish the designated task.\n\nThe different components can be composed together using the [LangChain Expression Language (LCEL)](https:\u002F\u002Flangchaindart.dev\u002F#\u002Fexpression_language\u002Fget_started).\n\n## Motivation\n\nLarge Language Models (LLMs) have revolutionized Natural Language Processing (NLP), serving as essential components in a wide range of applications, such as question-answering, summarization, translation, and text generation.\n\nThe adoption of LLMs is creating a new tech stack in its wake. However, emerging libraries and tools are predominantly being developed for the Python and JavaScript ecosystems. As a result, the number of applications leveraging LLMs in these ecosystems has grown exponentially.\n\nIn contrast, the Dart \u002F Flutter ecosystem has not experienced similar growth, which can likely be attributed to the scarcity of Dart and Flutter libraries that streamline the complexities associated with working with LLMs.\n\nLangChain.dart aims to fill this gap by abstracting the intricacies of working with LLMs in Dart and Flutter, enabling developers to harness their combined potential effectively.\n\n## Packages\n\nLangChain.dart has a modular design that allows developers to import only the components they need. The ecosystem consists of several packages:\n\n### [`langchain_core`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_core) [![langchain_core](https:\u002F\u002Fimg.shields.io\u002Fpub\u002Fv\u002Flangchain_core.svg)](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_core)\n\nContains only the core abstractions as well as LangChain Expression Language as a way to compose them together. \n\n> Depend on this package to build frameworks on top of LangChain.dart or to interoperate with it.\n\n### [`langchain`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain) [![langchain](https:\u002F\u002Fimg.shields.io\u002Fpub\u002Fv\u002Flangchain.svg)](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain)\n\nContains higher-level and use-case specific chains, agents, and retrieval algorithms that are at the core of the application's cognitive architecture.\n\n> Depend on this package to build LLM applications with LangChain.dart. \n> \n> This package exposes `langchain_core` so you don't need to depend on it explicitly.\n\n### [`langchain_community`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_community) [![langchain_community](https:\u002F\u002Fimg.shields.io\u002Fpub\u002Fv\u002Flangchain_community.svg)](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_community)\n\nContains third-party integrations and community-contributed components that are not part of the core LangChain.dart API.\n\n> Depend on this package if you want to use any of the integrations or components it provides.\n\n### Integration-specific packages\n\nPopular third-party integrations (e.g. [`langchain_openai`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_openai), [`langchain_google`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_google), [`langchain_ollama`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_ollama), etc.) are moved to their own packages so that they can be imported independently without depending on the entire `langchain_community` package.\n\n> Depend on an integration-specific package if you want to use the specific integration.\n\n| Package | Version | Description

Getting started\n\nTo start using LangChain.dart, add `langchain` as a dependency to your `pubspec.yaml` file. Also, include the dependencies for the specific integrations you want to use (e.g.`langchain_community`, `langchain_openai`, `langchain_google`, etc.):\n\n```yaml\ndependencies:\n langchain: {version}\n langchain_community: {version}\n langchain_openai: {version}\n langchain_google: {version}\n ...\n```\n\nThe most basic building block of LangChain.dart is calling an LLM on some prompt. LangChain.dart provides a unified interface for calling different LLMs. For example, we can use `ChatGoogleGenerativeAI` to call Google's Gemini model:\n\n```dart\nfinal model = ChatGoogleGenerativeAI(apiKey: googleApiKey);\nfinal prompt = PromptValue.string('Hello world!');\nfinal result = await model.invoke(prompt);\n\u002F\u002F Hello everyone! I'm new here and excited to be part of this community.\n```\n\nBut the power of LangChain.dart comes from chaining together multiple components to implement complex use cases. For example, a RAG (Retrieval-Augmented Generation) pipeline that would accept a user query, retrieve relevant documents from a vector store, format them using prompt templates, invoke the model, and parse the output:\n\n```dart\n\u002F\u002F 1. Create a vector store and add documents to it\nfinal vectorStore = MemoryVectorStore(\n embeddings: OpenAIEmbeddings(apiKey: openaiApiKey),\n);\nawait vectorStore.addDocuments(\n documents: [\n Document(pageContent: 'LangChain was created by Harrison'),\n Document(pageContent: 'David ported LangChain to Dart in LangChain.dart'),\n ],\n);\n\n\u002F\u002F 2. Define the retrieval chain\nfinal retriever = vectorStore.asRetriever();\nfinal setupAndRetrieval = Runnable.fromMap\u003CString>({\n 'context': retriever.pipe(\n Runnable.mapInput((docs) => docs.map((d) => d.pageContent).join('\\n')),\n ),\n 'question': Runnable.passthrough(),\n});\n\n\u002F\u002F 3. Construct a RAG prompt template\nfinal promptTemplate = ChatPromptTemplate.fromTemplates([\n (ChatMessageType.system, 'Answer the question based on only the following context:\\n{context}'),\n (ChatMessageType.human, '{question}'),\n]);\n\n\u002F\u002F 4. Define the final chain\nfinal model = ChatOpenAI(apiKey: openaiApiKey);\nconst outputParser = StringOutputParser\u003CChatResult>();\nfinal chain = setupAndRetrieval\n .pipe(promptTemplate)\n .pipe(model)\n .pipe(outputParser);\n\n\u002F\u002F 5. Run the pipeline\nfinal res = await chain.invoke('Who created LangChain.dart?');\nprint(res);\n\u002F\u002F David created LangChain.dart\n```\n\n## Documentation\n\n- [LangChain.dart documentation](https:\u002F\u002Flangchaindart.dev)\n- [Sample apps](https:\u002F\u002Fgithub.com\u002Fdavidmigloz\u002Flangchain_dart\u002Ftree\u002Fmain\u002Fexamples)\n- [LangChain.dart blog](https:\u002F\u002Fblog.langchaindart.dev)\n- [Project board](https:\u002F\u002Fgithub.com\u002Fusers\u002Fdavidmigloz\u002Fprojects\u002F2\u002Fviews\u002F1)\n\n## Community\n\nStay up-to-date on the latest news and updates on the field, have great discussions, and get help in the official [LangChain.dart Discord server](https:\u002F\u002Fdiscord.gg\u002Fx4qbhqecVR).\n\n[![LangChain.dart Discord server](https:\u002F\u002Finvidget.switchblade.xyz\u002Fx4qbhqecVR?theme=light)](https:\u002F\u002Fdiscord.gg\u002Fx4qbhqecVR)\n\n## Contribute\n\n| 📢 **Call for Collaborators** 📢 |\n|-------------------------------------------------------------------------|\n| We are looking for collaborators to join the core group of maintainers. |\n\nNew contributors welcome!

Dart\u002FFlutter 应用程序。\n\n## 什么是 LangChain.dart？\n\nLangChain.dart 是由 [Harrison Chase](https:\u002F\u002Fwww.linkedin.com\u002Fin\u002Fharrison-chase-961287118) 创建的流行 Python 框架 [LangChain](https:\u002F\u002Fgithub.com\u002Fhwchase17\u002Flangchain) 的非官方 Dart 移植版。\n\nLangChain 提供了一组开箱即用的组件，用于与语言模型协作，并提供了一个标准接口，可以将这些组件串联起来，以实现更高级的用例（例如聊天机器人、带有 RAG 的问答系统、智能体、摘要生成、翻译、信息抽取、推荐系统等）。\n\n这些组件可以分为几个核心模块：\n\n![LangChain.dart](https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdavidmigloz_langchain_dart_readme_16f6fc4fa5bf.png)\n\n- 📃 **模型输入输出：** LangChain 提供了一个统一的 API，用于与各种 LLM 提供商（如 OpenAI、Google、Mistral、Ollama 等）交互，使开发者能够轻松地在不同提供商之间切换。此外，它还提供了管理模型输入（提示模板和示例选择器）以及解析模型输出（输出解析器）的工具。\n- 📚 **检索：** 帮助加载用户数据（通过文档加载器）、对其进行转换（使用文本分割器）、提取其语义（使用嵌入模型）、存储（在向量数据库中）并检索出来（通过检索器），以便将其用于增强模型的回答（即检索增强生成或 RAG）。\n- 🤖 **智能体：** 利用 LLM 来做出明智决策的“机器人”，决定使用哪些可用工具（如网络搜索、计算器、数据库查询等）来完成指定的任务。\n\n不同的组件可以使用 [LangChain 表达式语言 (LCEL)](https:\u002F\u002Flangchaindart.dev\u002F#\u002Fexpression_language\u002Fget_started) 组合在一起。\n\n## 动机\n\n大型语言模型（LLMs）彻底改变了自然语言处理（NLP），成为问答、摘要生成、翻译和文本生成等各种应用中的关键组件。\n\nLLMs 的普及正在催生一个新的技术栈。然而，新兴的库和工具主要是在 Python 和 JavaScript 生态系统中开发的。因此，在这些生态系统中利用 LLM 的应用程序数量呈指数级增长。\n\n相比之下，Dart\u002FFlutter 生态系统并未经历类似的增长，这很可能归因于缺乏能够简化与 LLM 交互复杂性的 Dart 和 Flutter 库。\n\nLangChain.dart 旨在填补这一空白，通过抽象 Dart 和 Flutter 中与 LLM 交互的复杂性，使开发者能够有效地发挥它们的联合潜力。\n\n## 软件包\n\nLangChain.dart 采用模块化设计，允许开发者仅导入所需的组件。该生态体系由多个软件包组成：\n\n### [`langchain_core`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_core) [![langchain_core](https:\u002F\u002Fimg.shields.io\u002Fpub\u002Fv\u002Flangchain_core.svg)](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_core)\n\n仅包含核心抽象以及用于组合这些抽象的 LangChain 表达式语言。\n\n> 若要基于 LangChain.dart 构建框架或与其互操作，请依赖此软件包。\n\n### [`langchain`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain)

LangChain.dart 构建 LLM 应用程序，请依赖此软件包。 \n> \n> 此软件包公开了 `langchain_core`，因此您无需显式依赖它。\n\n### [`langchain_community`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_community)

的第三方集成和社区贡献的组件。\n\n> 如果您希望使用其中提供的任何集成或组件，请依赖此软件包。\n\n### 针对接入的专用包\n\n流行的第三方集成（例如 [`langchain_openai`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_openai)、[`langchain_google`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_google)、[`langchain_ollama`](https:\u002F\u002Fpub.dev\u002Fpackages\u002Flangchain_ollama) 等）已被拆分到各自的专用包中，以便可以独立导入，而无需依赖整个 `langchain_community` 包。\n\n> 如果您想使用特定的集成，请依赖相应的专用包。\n\n| 包 | 版本 | 描述

快速入门\n\n要开始使用LangChain.dart，需在`pubspec.yaml`文件中添加`langchain`作为依赖项。同时，还需包含您希望使用的特定集成的依赖项（例如`langchain_community`、`langchain_openai`、`langchain_google`等）：\n\n```yaml\ndependencies:\n langchain: {version}\n langchain_community: {version}\n langchain_openai: {version}\n langchain_google: {version}\n ...\n```\n\nLangChain.dart中最基本的构建块是基于某个提示调用LLM。LangChain.dart提供了一个统一的接口来调用不同的LLM。例如，我们可以使用`ChatGoogleGenerativeAI`来调用Google的Gemini模型：\n\n```dart\nfinal model = ChatGoogleGenerativeAI(apiKey: googleApiKey);\nfinal prompt = PromptValue.string('Hello world!');\nfinal result = await model.invoke(prompt);\n\u002F\u002F 大家好！我是新来的，很高兴能成为这个社区的一员。\n```\n\n然而，LangChain.dart的强大之处在于可以将多个组件串联起来，以实现复杂的用例。例如，一个RAG（检索增强生成）管道，它可以接收用户查询，从向量存储中检索相关文档，使用提示模板对其进行格式化，调用模型，并解析输出：\n\n```dart\n\u002F\u002F 1. 创建向量存储并添加文档\nfinal vectorStore = MemoryVectorStore(\n embeddings: OpenAIEmbeddings(apiKey: openaiApiKey),\n);\nawait vectorStore.addDocuments(\n documents: [\n Document(pageContent: 'LangChain是由Harrison创建的'),\n Document(pageContent: 'David在LangChain.dart中将LangChain移植到了Dart语言上'),\n ],\n);\n\n\u002F\u002F 2. 定义检索链\nfinal retriever = vectorStore.asRetriever();\nfinal setupAndRetrieval = Runnable.fromMap\u003CString>({\n 'context': retriever.pipe(\n Runnable.mapInput((docs) => docs.map((d) => d.pageContent).join('\\n')),\n ),\n 'question': Runnable.passthrough(),\n});\n\n\u002F\u002F 3. 构建RAG提示模板\nfinal promptTemplate = ChatPromptTemplate.fromTemplates([\n (ChatMessageType.system, '请仅根据以下内容回答问题：\\n{context}'),\n (ChatMessageType.human, '{question}'),\n]);\n\n\u002F\u002F 4. 定义最终链\nfinal model = ChatOpenAI(apiKey: openaiApiKey);\nconst outputParser = StringOutputParser\u003CChatResult>();\nfinal chain = setupAndRetrieval\n .pipe(promptTemplate)\n .pipe(model)\n .pipe(outputParser);\n\n\u002F\u002F 5. 运行管道\nfinal res = await chain.invoke('谁创建了LangChain.dart？');\nprint(res);\n\u002F\u002F David创建了LangChain.dart\n```\n\n## 文档\n\n-

快速上手指南\n\nLangChain.dart 是流行 Python 框架 LangChain 的非官方 Dart 移植版本，旨在帮助开发者轻松构建基于大语言模型（LLM）的 Dart\u002FFlutter 应用。它提供了统一的接口来连接各种 LLM 提供商、管理提示词、处理检索增强生成（RAG）以及构建智能代理。\n\n## 环境准备\n\n在开始之前，请确保您的开发环境满足以下要求：\n\n* **操作系统**: Windows, macOS, 或 Linux\n* **Dart SDK**: 版本 >= 3.0.0 (推荐最新稳定版)\n* **Flutter SDK**: 如果您计划开发 Flutter 应用，请安装最新稳定版 Flutter\n* **API Key**: 您需要拥有所选 LLM 提供商（如 OpenAI, Google, Ollama 等）的有效 API Key\n\n**前置检查：**\n在终端运行以下命令确认环境已就绪：\n```bash\ndart --version\n# 或者如果是 Flutter 项目\nflutter doctor\n```\n\n## 安装步骤\n\nLangChain.dart 采用模块化设计，您只需安装所需的包。通常建议直接依赖主包 `langchain`，它会自动包含核心功能 `langchain_core`。如果您需要使用特定的模型提供商（如 OpenAI），还需安装对应的集成包。\n\n### 1. 初始化项目\n如果您还没有项目，先创建一个：\n```bash\ndart create my_llm_app\ncd my_llm_app\n# 或者创建 Flutter 项目\nflutter create my_llm_app\ncd my_llm_app\n```\n\n### 2. 添加依赖\n编辑 `pubspec.yaml` 文件，添加核心库和您需要的集成包。以下以 **OpenAI** 为例：\n\n```yaml\ndependencies:\n langchain: ^0.3.0 # 请替换为 pub.dev 上的最新版本\n langchain_openai: ^0.3.0 # OpenAI 集成包\n```\n\n> **提示**：如果您使用国内网络环境访问 pub.dev 较慢，可以配置国内镜像源。\n> 在项目根目录创建或编辑 `.dart-tool\u002Fpub-env` 或在命令行临时指定：\n> ```bash\n> export PUB_HOSTED_URL=https:\u002F\u002Fpub.flutter-io.cn\n> export STORAGE_BASE_URL=https:\u002F\u002Fstorage.flutter-io.cn\n> ```\n> *(Windows PowerShell: `$env:PUB_HOSTED_URL=\"https:\u002F\u002Fpub.flutter-io.cn\"; $env:STORAGE_BASE_URL=\"https:\u002F\u002Fstorage.flutter-io.cn\"`)*\n\n### 3. 获取依赖\n运行以下命令安装包：\n```bash\ndart pub get\n# 或者\nflutter pub get\n```\n\n## 基本使用\n\n以下是一个最简单的示例，展示如何使用 `langchain` 和 `langchain_openai` 调用大模型进行对话。\n\n### 代码示例 (`main.dart`)\n\n```dart\nimport 'package:langchain\u002Flangchain.dart';\nimport 'package:langchain_openai\u002Flangchain_openai.dart';\n\nvoid main() async {\n \u002F\u002F 1. 初始化 LLM (以 OpenAI 为例)\n \u002F\u002F 请确保在环境变量中设置了 OPENAI_API_KEY，或者直接在此处传入\n final llm = ChatOpenAI(\n apiKey: const String.fromEnvironment('OPENAI_API_KEY'), \n model: 'gpt-4o',\n );\n\n \u002F\u002F 2. 定义提示词模板\n final promptTemplate = PromptTemplate.fromTemplate(\n '请用简短的一句话解释什么是 {topic}？',\n );\n\n \u002F\u002F 3. 构建链 (Chain): 将提示词模板与 LLM 连接\n final chain = promptTemplate | llm;\n\n \u002F\u002F 4. 执行调用\n final response = await chain.invoke({\n 'topic': 'LangChain.dart',\n });\n\n \u002F\u002F 5. 输出结果\n print(response.content);\n}\n```\n\n### 运行说明\n\n1. 将上述代码保存为 `bin\u002Fmain.dart` (对于 Dart 项目) 或 `lib\u002Fmain.dart` (对于 Flutter 项目，需适当调整入口)。\n2. 设置您的 API Key。在终端中运行：\n ```bash\n export OPENAI_API_KEY=\"sk-your-actual-api-key-here\"\n ```\n *(Windows PowerShell: `$env:OPENAI_API_KEY=\"sk-your-actual-api-key-here\"`)*\n3. 运行程序：\n ```bash\n dart run bin\u002Fmain.dart\n # 或者\n flutter run\n ```\n\n您将看到模型返回的关于 \"LangChain.dart\" 的简短解释。\n\n---\n**下一步探索**：\n* 尝试更换 `langchain_ollama` 或 `langchain_google` 包来使用本地模型或其他云服务。\n* 查阅官方文档了解如何构建 RAG（检索增强生成）应用或智能 Agent。","某初创团队正利用 Flutter 开发一款跨平台移动应用，旨在让用户通过自然语言对话快速检索企业内部的技术文档库。\n\n### 没有 langchain_dart 时\n- **多模型适配困难**：开发者需为 OpenAI、Google 等不同大模型厂商分别编写独立的 HTTP 请求代码，切换模型时几乎要重构整个网络层。\n- **数据处理链路断裂**：缺乏统一的文档加载与文本分割工具，团队不得不手动解析 PDF\u002FMarkdown 文件并自行实现切片逻辑，极易出现上下文截断错误。\n- **RAG 架构从零搭建**：构建“检索增强生成”功能时，需独立整合向量数据库、嵌入模型和检索算法，导致开发周期长达数周且代码耦合度极高。\n- **提示词管理混乱**：提示词模板硬编码在业务逻辑中，难以动态调整变量或复用最佳实践，导致模型输出不稳定且难以调试。\n\n### 使用 langchain_dart 后\n- **统一接口无缝切换**：借助 Model I\u002FO 模块的标准 API，团队仅需修改一行配置即可在 Ollama 本地模型与云端大模型间自由切换，无需改动核心业务代码。\n- **内置数据流水线**：直接调用现成的 Document Loaders 和 Text Splitters，轻松完成多种格式文档的读取、清洗与智能分块，大幅降低数据预处理门槛。\n- **快速组装 RAG 应用**：利用 LCEL（LangChain 表达式语言）以声明式方式将检索器、向量存储与大模型串联，仅用数百行代码便在三天内上线了高精度的问答功能。\n- **标准化提示工程**：通过 Prompt Templates 组件化管理提示词，支持动态注入用户上下文与示例，显著提升了回答的准确性与一致性。\n\nlangchain_dart 成功填补了 Flutter 生态在大模型应用开发上的空白，让移动端团队能以最低成本构建生产级的 AI 智能应用。","https:\u002F\u002Foss.gittoolsai.com\u002Fimages\u002Fdavidmigloz_langchain_dart_af65c361.png","davidmigloz","David Miguel
