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

An agent prompt reading "Add Google sign-in to the profile screen" on the left; on the right, the firebase-auth and flutter-app-architecture skills are auto-selected from a list of dozens

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.

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."

🗂️ Rules and combined sets (legacy)

Before skills existed, this repo shipped rule files you pasted into a config, plus pre-merged bundles squeezed under Windsurf's character cap. Both still work and both are still updated, but skills are the recommended path — they load contextually instead of consuming your context window on every request.

Reach for these only if your tool has no skills support, or you want one static file you fully control:

  • rules/ — six broad foundation files: effective_dart.md, flutter_app_architecture.md, flutter_errors.md, dart_3_updates.md, testing.md, code_review.md. Drop them in your project and reference them by name: "Read @rules/effective_dart.md and follow its conventions." Package-specific guidance (Bloc, Riverpod, Firebase, Mockito…) is skills-only now.
  • combined/ — seven topic bundles, each in a full and an __under_6K variant. Paste one into your global or local rules config and you're done. The trimmed variants stay under 6,000 characters to fit Windsurf's global_rules.md hard limit.

GitHub Copilot lives here rather than in the skills section, because it has no SKILL.md support. Three options, in the order Copilot documents them:

  • Copy a combined/ bundle to .github/copilot-instructions.md for repo-wide guidance.
  • Copy rules/ files into .github/instructions/ as <name>.instructions.md, each with applyTo: "**/*.dart" frontmatter, so they only load for Dart files.
  • Copilot also reads a root AGENTS.md, so a bundle pasted there works for Copilot, Codex, and Antigravity at once.

📏 Recommended file sizes by tool

Size guidance from each tool's own official documentation, for rule/instruction files and for SKILL.md files (accessed 2026-07-11).

ToolRule file — recommended sizeSKILL.md — recommended size
Claude CodeCLAUDE.md: under 200 lines (soft)Under 500 lines (soft); description 1,536 chars (hard)
Cursor.mdc rule: under 500 lines (soft)No numeric limit — "keep focused, move detail to separate files"
OpenAI CodexAGENTS.md: no limit statedSkill bundle: zip ≤ 50 MB, uncompressed file ≤ 25 MB, ≤ 500 files/version (no per-SKILL.md text limit)
Google Antigravityrule file: 12,000 chars each (hard)No numeric limit stated
Windsurfglobal_rules.md: 6,000 chars; .windsurf/rules/*.md: 12,000 chars/file (hard)No numeric limit — "keeps your context window lean"
GitHub Copilotcopilot-instructions.md: ≤ 2 pages (soft, approx.)Not supported — no repo-level SKILL.md

Notes:

  • Hard = enforced/truncated at the limit; soft = a documented quality recommendation.
  • Only Claude Code publishes a numeric SKILL.md length recommendation (under 500 lines). Cursor, Windsurf, and Antigravity just say "keep it focused/lean" with no figure; OpenAI documents skill-bundle limits (50 MB zip / 25 MB per file / 500 files) rather than a text length; and GitHub Copilot has no repo-level SKILL.md — it uses copilot-instructions.md plus path-specific *.instructions.md (no size limit stated for the latter).
  • Claude Code loads CLAUDE.md in full regardless of length, but notes files over 200 lines "consume more context and reduce adherence"; its auto-memory MEMORY.md loads only the "first 200 lines or 25KB, whichever comes first."
  • Windsurf is still named Windsurf; its docs are served through Cognition (docs.windsurf.com → docs.devin.ai) and reference .windsurf/rules and .windsurf/skills.
  • This repo keeps the combined/ sets under 6,000 characters to satisfy the strictest hard limit above (Windsurf global_rules.md).

📌 No opinions, just documentation

Every skill is sourced from official documentation — no personal preferences or subjective interpretations. That's intentional. You're free to alter them to taste, but this repo stays objective by sticking to the source.

One consequence worth knowing: skills can contradict each other, because their sources do. If one package recommends a folder layout and another recommends a different one, you'll see both.

Content is re-fetched from upstream docs on a schedule, so skills track the official guidance as it changes rather than freezing at whatever was true when they were written.

🛠️ Contributing

Contributions are welcome:

  1. Fork this repository.
  2. Add or modify a skill in skills/, or a rule in rules/.
  3. Open a pull request explaining the change.

Include an official documentation link for anything you add or change. That's the one hard requirement — it's what keeps the repo objective and reviewable. If your source isn't already listed in ATTRIBUTION.md, add it there with its license — and if that license isn't a permissive one, restate the guidance instead of quoting it.

The underlying documentation keeps its own terms. Most of it is CC BY 4.0 (Flutter, Dart, Firebase), with code samples under BSD-3 or Apache 2.0, package READMEs under MIT or Apache 2.0, and a few sources — Apple, Google Play, RevenueCat — that aren't openly licensed and are therefore restated as fact rather than copied. ATTRIBUTION.md maps every source to its license and to the skills built on it.

If you redistribute this repo or lift a single skill out of it, keep the source links — that's what the CC BY attribution requirement actually asks for.

Patrol E2E Testing Skill

Design, implement, and run end-to-end (E2E) tests using Patrol 4.x in Flutter projects.

When to Use

Use this skill when:

  • A new screen or user flow needs E2E test coverage.
  • A feature interacts with native components (permissions, notifications, system dialogs, deep links).
  • A UI bug should be captured as a regression test.
  • Cross-platform behavior (Android / iOS / Web) must be validated.
  • Setting up Patrol in a new or existing Flutter project.

Setup

Follow the official Patrol documentation for installation and project initialization: https://patrol.leancode.co/documentation#setup

Key Patrol conventions:

  • Add patrol as a dev dependency.
  • Place tests in patrol_test/.
  • Name test files with a _test.dart suffix.
  • Execute tests with patrol test.

Workflow

Follow these steps when implementing or updating Patrol tests.

1. Identify the user journey

Break the feature into:

  • Actions: taps, scrolls, input, navigation, deep links.
  • Observable outcomes: visible text, screen changes, enabled buttons, dialogs.

Rules:

  • One test per primary (happy-path) journey.
  • Separate tests for critical edge cases.
  • Avoid combining unrelated flows in a single test.

2. Structure the Patrol test

Basic Patrol structure:

import 'package:flutter_test/flutter_test.dart';
import 'package:patrol/patrol.dart';

void main() {
  patrolTest(
    'user can log in successfully',
    ($) async {
      await $.pumpWidgetAndSettle(const MyApp());

      const email = String.fromEnvironment('E2E_EMAIL');
      const password = String.fromEnvironment('E2E_PASSWORD');

      await $(#emailField).enterText(email);
      await $(#passwordField).enterText(password);
      await $(#loginButton).tap();

      await $.waitUntilVisible($(#homeScreenTitle));

      expect($(#homeScreenTitle).text, equals('Welcome'));
    },
  );
}

Key concepts:

  • Use patrolTest() instead of testWidgets().
  • $ is the Patrol tester.
  • Use $(#keyName) to find widgets by Key.
  • Use explicit wait conditions (e.g., waitUntilVisible).

3. Handle native dialogs

For OS-level permission dialogs:

patrolTest('grants camera permission', ($) async {
  await $.pumpWidgetAndSettle(const MyApp());

  await $(#openCameraButton).tap();

  if (await $.native.isPermissionDialogVisible()) {
    await $.native.grantPermission();
  }

  await $.waitUntilVisible($(#cameraPreview));
});

Use native automation only when required by the feature.

4. Selector & interaction quick reference

Finding widgets:

$('some text')        // by text
$(TextField)          // by type
$(Icons.arrow_back)   // by icon

Tapping:

// Tap a widget containing a specific text label
await $(Container).$('click').tap();

// Tap a container that contains an ElevatedButton
await $(Container).containing(ElevatedButton).tap();

// Tap only the enabled ElevatedButton
await $(ElevatedButton)
    .which<ElevatedButton>(
      (b) => b.enabled,
    )
    .tap();

Entering text:

// Enter text into the second TextField on screen
await $(TextField).at(1).enterText('your input');

Scrolling:

await $(widget_you_want_to_scroll_to).scrollTo();

Native interactions:

// Grant permission while app is in use
await $.native.grantPermissionWhenInUse();

// Open notification shade and tap a notification by text
await $.native.openNotifications();
await $.native.tapOnNotificationBySelector(
  Selector(textContains: 'text'),
);

5. Running Patrol tests

Run all tests:

patrol test

Run a specific file with live reload (development mode):

patrol develop -t integration_test/my_test.dart

Run a specific file:

patrol test --target patrol_test/login_test.dart

Run on web:

patrol test --device chrome

Headless web (CI):

patrol test --device chrome --web-headless true

Filter by tags:

patrol test --tags android

6. Stabilization patterns

Flaky tests undermine confidence. Apply these patterns:

// AVOID — arbitrary delay
await Future.delayed(Duration(seconds: 3));

// PREFER — explicit wait condition
await $.waitUntilVisible($(#targetWidget));

// For animations, pump until settled
await $.pumpAndSettle();
  • Never use Future.delayed as a synchronization mechanism.
  • Use waitUntilVisible or waitUntilExists to wait for UI state.
  • Set settleTimeout in PatrolTesterConfig for slow CI environments.

Output requirements

When applied, this skill produces:

  1. Patrol test(s) covering the specified feature.
  2. Any required widget Key additions to production code.
  3. Exact patrol test command(s) to execute locally.
  4. Notes explaining stabilization or timing decisions.

Checkpoint: Run patrol test --target <file> locally to confirm the test passes before committing.

Quality bar

A valid Patrol test must be:

  • Deterministic — no arbitrary delays; uses explicit wait conditions.
  • Readable — clear test name describing the user journey.
  • Minimal but complete — one assertion chain per journey.
  • Secret-safe — credentials loaded from String.fromEnvironment, never hardcoded.
  • CI-ready — passes headless with --web-headless true or on emulator.
