dart-run-static-analysis

/dart-run-static-analysis

Execute `dart analyze` to identify warnings and errors, and use `dart fix --apply` to automatically resolve mechanical lint issues. Use during development to ensure code quality and before committing changes.

dart-setup-ffi-assets

/dart-setup-ffi-assets

Guides agents in compiling and packaging C/C++ source code into dynamic or static libraries (Code Assets) using Dart's Native Assets hook system (via hook/build.dart and hook/link.dart utilizing package:hooks and package:native_toolchain_c). Use when a user asks to: 'setup native assets', 'compile C/C++ source code', 'bundle dynamic libraries', 'build native C code', 'link native assets', 'implement build.dart or link.dart hooks', or 'integrate C/C++ interop in Dart/Flutter'. Helps agents avoid manual toolchain orchestration and configures secure hash-validated binary downloads or advanced linker tree-shaking with package:record_use mapping.

dart-use-ffigen

/dart-use-ffigen

Guide agents to use `package:ffigen` to automatically generate FFI bindings instead of writing them manually. Use this skill when a task involves writing new FFI bindings, extending C/Objective-C/Swift integrations, or replacing hand-crafted `dart:ffi` setups.

dart-use-pattern-matching

/dart-use-pattern-matching

Use switch expressions and pattern matching where appropriate

dart-use-primary-constructors

/dart-use-primary-constructors

Help users write syntactically and semantically correct primary constructors in Dart, and migrate/use the new constructor syntax, empty-body semicolon syntax, in-body initializer list syntax, and abbreviated concise constructor syntax.

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

Add the marketplace for Claude Code plugins:

claude plugin marketplace add flutter/agent-plugins

Install the Claude plugin for Dart and Flutter:

claude plugin install dart-flutter@dart-flutter

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:

codex plugin add dart-flutter@dart-flutter

Cursor Plugin

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

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

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

Updating Plugins

To update, run the following command:

npx [email protected] update

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

Use this agent when you need expert assistance with Flutter mobile development tasks, including code analysis, widget creation, debugging, performance optimization, or architectural decisions. Examples: <example>Context: User is working on a Flutter app and faces issues with navigation. user: 'My Navigator.push isn't updating the UI correctly when moving to a new screen' assistant: 'Let me use the flutter-dev agent to analyze your navigation setup and provide a solution' <commentary>Since this is a Flutter-specific navigation issue, use the flutter-dev agent to provide expert guidance on Navigator problems.</commentary></example> <example>Context: User wants to create a custom widget that aligns with their app's design system. user: 'I need to create a custom button widget that matches our app's design system' assistant: 'I'll use the flutter-dev agent to create a button widget that aligns with your existing codebase structure and design patterns' <commentary>The user needs a Flutter widget that follows existing patterns, so use the flutter-dev agent.</commentary></example>
