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

Refer to Get started developing with AI for detailed instructions on how to install the plugins for your preferred agent.

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 |
