--- title: AI rules for Flutter and Dart shortTitle: AI rules description: >- Learn how to add AI rules to tools that accelerate your development workflow. --- This guide covers how you can leverage AI rules to streamline your Flutter and Dart development. ## Overview AI-powered editors use rules files to provide context and instructions to an underlying LLM. These files help you: * Customize AI behavior to your team's needs. * Enforce project best practices for code style and design. * Provide critical project context to the AI. Download the Flutter and Dart rules template ## Environments that support rules Many AI environments support rules files to guide LLM behavior. Here are some common examples and their corresponding rule file or directory names: | Environment | Rules file or directory | Configuration instructions | |:---------------------|:----------------------------------|:------------------------------------------------------| | Copilot-powered IDEs | `.github/copilot-instructions.md` | [Configure instructions for Copilot][copilot] | | Claude Code | `CLAUDE.md` | [Configure rules for Claude Code][claude] | | Cursor | `AGENTS.md` | [Configure rules in Cursor][cursor] | | Firebase Studio | `.idx/airules.md` | [Configure instructions in Firebase Studio][firebase] | | Gemini CLI | `GEMINI.md` | [Configure context in Gemini CLI][gemini-cli] | | Google Antigravity | `.agent/rules/.md` | [Configure rules for Antigravity Agent][antigravity] | | JetBrains IDEs | `.junie/guidelines.md` | [Configure guidelines for Junie][junie] | | VS Code | `.instructions.md` | [Configure instructions in VS Code][vs-code] | | Windsurf | `.windsurf/rules/.md` | [Configure rules in Windsurf][windsurf] | {:.table .table-striped} :::note Support is evolving Support for rules files is still evolving. Please check the documentation for your specific development environment for the most up-to-date naming conventions and instructions. ::: [copilot]: https://code.visualstudio.com/docs/copilot/customization/custom-instructions#_use-a-githubcopilotinstructionsmd-file [claude]: https://www.anthropic.com/engineering/claude-code-best-practices#1-customize-your-setup [cursor]: https://cursor.com/docs/context/rules [firebase]: https://firebase.google.com/docs/studio/set-up-gemini#custom-instructions [gemini-cli]: https://geminicli.com/docs/cli/gemini-md [antigravity]: https://antigravity.google/docs/rules [junie]: https://www.jetbrains.com/help/junie/customize-guidelines.html [vs-code]: https://code.visualstudio.com/docs/copilot/customization/custom-instructions#_use-instructionsmd-files [windsurf]: https://docs.windsurf.com/windsurf/cascade/memories#rules ## Create rules for your editor You can adapt our Flutter and Dart rules template for your specific environment. To do so, follow these steps: 1. Download the Flutter and Dart rules template: rules.md 1. In an LLM like [Gemini][], attach the `rules.md` file that you downloaded in the last step. 1. Provide a prompt to reformat the file for your desired editor. Example prompt: ```text Convert the attached rules.md file into a guidelines.md file for Gemini CLI. Make sure to use the styles required for a guidelines.md file. ``` 1. Review the LLM's output and make any necessary adjustments. 1. Follow your environment's instructions to add the new rules file. This may involve adding to an existing file or creating a new one. 1. Verify that your AI assistant is using the new rules to guide its responses. [Gemini]: https://gemini.google.com/
