Flutter Agent Plugins

Agent plugins for Flutter, maintained by the Flutter team.

A collection of plugins designed to extend AI agent capabilities for Flutter development. These plugins bundle together skills, MCP server configuration, and rules to provide tailored workflows and instructions for happy path Flutter development. By giving the agent domain expertise and repeatable workflows, you drastically reduce mistakes and ensure agents reliably complete tasks following best practices.

Plugins can package various customizations together. A key component of these plugins is Agent Skills, which are simple folders of files that can be seen as complementary to MCP: where MCP gives an agent access to specialized tools, a Skill teaches the agent “how” to use tools for a specific task.

You can also install the Dart skills for Dart tasks.

Installation

To install the plugins into your project, run the following command. The --agent universal flag puts them in the standard .agents/skills folder that most agents use.

npx [email protected] add flutter/agent-plugins --skill '*' --agent universal --yes

Claude Code Plugin

1. Add the marketplace for Claude Code plugins:

claude plugin marketplace add flutter/agent-plugins

2. Install the Claude plugin for Dart and Flutter:

claude plugin install dart-flutter@dart-flutter

3. Verify the installation:

claude plugin marketplace list

\n### Codex Plugin

Add the Dart and Flutter marketplace for Codex plugins:

codex plugin marketplace add flutter/agent-plugins

Install the Dart and Flutter plugin:

Cursor Plugin

You can test this plugin locally by copying it to your Cursor plugins directory.

1. Copy the repository directory to your local Cursor plugins folder:

mkdir -p ~/.cursor/plugins/local
cp -r /path/to/flutter/agent-plugins ~/.cursor/plugins/local/dart-flutter

2. Restart Cursor. The editor will automatically discover and load the skills under skills/ and configure the MCP server defined in .mcp.json.

Updating Plugins

Available Skills

Skill	Description	Example prompt
flutter-add-integration-test	Configures Flutter Driver for app interaction and converts MCP actions into permanent integration tests. Use when adding integration testing to a project, exploring UI components via MCP, or automating user flows with the integration_test package.	Add an integration test that validates the checkout experience
flutter-add-widget-preview	Adds interactive widget previews to the project using the previews.dart system. Use when creating new UI components or updating existing screens to ensure consistent design and interactive testing.	Create a preview for the ProductCard widget with different price states
flutter-add-widget-test	Implement a component-level test using WidgetTester to verify UI rendering and user interactions (tapping, scrolling, entering text). Use when validating that a specific widget displays correct data and responds to events as expected.	Add a widget test for the CustomButton to verify the onTap callback is called
flutter-apply-architecture-best-practices	Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.	Refactor the authentication flow to follow the recommended layered architecture
flutter-build-responsive-layout	Use LayoutBuilder, MediaQuery, or Expanded/Flexible to create a layout that adapts to different screen sizes. Use when you need the UI to look good on both mobile and tablet/desktop form factors.	Make the home screen responsive so it displays a grid on tablets and a list on phones
flutter-fix-layout-issues	Fixes Flutter layout errors (overflows, unbounded constraints) using Dart and Flutter MCP tools. Use when addressing "RenderFlex overflowed", "Vertical viewport was given unbounded height", or similar layout issues.	Fix the overflow error on the profile page when the keyboard is visible
flutter-implement-json-serialization	Create model classes with fromJson and toJson methods using dart:convert. Use when manually mapping JSON keys to class properties for simple data structures.	Implement JSON serialization for the User model class
flutter-setup-declarative-routing	Configure MaterialApp.router using a package like go_router for advanced URL-based navigation. Use when developing web applications or mobile apps that require specific deep linking and browser history support.	Set up GoRouter with paths for home, details, and settings
flutter-setup-localization	Add flutter_localizations and intl dependencies, enable "generate true" in pubspec.yaml, and create an l10n.yaml configuration file. Use when initializing localization support for a new Flutter project.	Setup localization and add English and Spanish translations
flutter-use-http-package	Use the http package to execute GET, POST, PUT, or DELETE requests. Use when you need to fetch from or send data to a REST API.	Use the http package to fetch the list of products from the API
