Flutter AI Skills for Claude Code, Codex, Cursor, Antigravity, and Other AI Coding Agents

36 Flutter and Dart skills your coding agent loads by itself, sourced only from official documentation.

A skill is a folder with a SKILL.md file. Your agent reads the description, decides a task matches, and pulls in the guidance — you don't paste anything into a rules file or remember to @-mention a doc. Install once, and Firebase Auth guidance shows up when you touch auth, Riverpod guidance when you touch providers.

A comprehensive, (almost) non-opinionated collection: everything here is derived from official Flutter, Dart, Firebase, and package documentation. No personal preferences, no invented conventions.

⚡ Quick start

npx skills add evanca/flutter-ai-rules

That's it. The Skills CLI discovers the packages under skills/ and installs them for supported agents. It needs Node 22.20 or newer — on older versions it exits with SyntaxError: ... does not provide an export named 'styleText' before it does anything. Every other install route below works on any Node version, or none at all.

Browse before installing, or take just one:

npx skills add evanca/flutter-ai-rules --list
npx skills add evanca/flutter-ai-rules --skill flutter-best-practices

Install as a plugin

This repo is also a plugin marketplace, so agents that support plugins can install the whole set and keep it updated in place. The manifests live at .claude-plugin/, .codex-plugin/, .cursor-plugin/, .agents/plugins/, and plugin.json — all pointing at the same skills/ directory.

Claude Code — plugin marketplaces:

/plugin marketplace add evanca/flutter-ai-rules
/plugin install flutter-ai-skills@flutter-ai-rules

Skills then load as flutter-ai-skills:bloc, flutter-ai-skills:riverpod, and so on.

Codex — plugins:

codex plugin marketplace add evanca/flutter-ai-rules
codex plugin install flutter-ai-skills@flutter-ai-rules

Cursor — plugins: in Cursor, run /add-plugin, or add the repo as a team marketplace under Dashboard → Settings → Plugins → Import from Repo:

https://github.com/evanca/flutter-ai-rules

Antigravity — plugins:

git clone --depth 1 https://github.com/evanca/flutter-ai-rules.git
agy plugin install ./flutter-ai-rules

Windsurf / Devin has no plugin manifest, but Cascade already scans .agents/skills/ and ~/.agents/skills/, so the manual copy below is the install path. GitHub Copilot doesn't read SKILL.md at all — see Rules and combined sets for what to use instead.

Prefer to do it by hand? Copy or symlink any skill folder into your agent's skills directory — .claude/skills/, .cursor/skills/, .codex/skills/, .agents/skills/ (Antigravity, Codex, Windsurf), .windsurf/skills/. Or vendor the whole set into your project:

git clone --depth 1 https://github.com/evanca/flutter-ai-rules.git temp_repo && mkdir -p .skills && cp -r temp_repo/skills/* .skills && rm -rf temp_repo

With a .skills/ folder you can also reference a skill explicitly when you want it: "Read @.skills/bloc/SKILL.md and create test coverage for the new methods."
