Flutter Agent Skills

flutter/skills is the official Flutter team Agent Skills repository. It gives AI coding agents repeatable, Flutter-specific workflows for common app work: layout errors, widget previews, widget tests, integration tests, responsive layouts, layered architecture, routing, localization, JSON serialization, and HTTP requests.

The README explicitly frames skills as complementary to MCP: MCP gives the agent specialized tools, while a skill teaches the agent how to use tools for a specific task. That makes this pack useful for Claude Code, Codex, Gemini CLI, and any skill-aware coding assistant working inside Flutter apps.

Knowledge Freshness

The repository is maintained by the Flutter team and the representative skills include metadata showing recent 2026 updates. Flutter SDK behavior, Dart language features, package APIs, integration testing, widget preview systems, MCP tooling, and recommended architecture patterns can change.

Use these skills to guide workflow and best practices, then verify exact commands, package versions, SDK constraints, device targets, and test behavior against the target Flutter project and current Flutter documentation.

Retrieval Sources

This listing is grounded in:

• The flutter/skills repository README.
• The public skills.sh listing for Flutter skills.
• Representative SKILL.md files for layout debugging, integration tests, and architecture best practices.
• The repository license text.
• Current GitHub repository metadata from the official Flutter organization.

Core Workflow

Install all Flutter skills into the standard universal skill location:

npx skills add flutter/skills --skill '*' --agent universal --yes

Update installed skills:

npx skills update

The README recommends using the universal .agents/skills target so most agents can discover the installed skills.

Capability Scope

The repository currently lists these Flutter skills:

Production Rules

Use these skills with project-specific Flutter discipline:

• Inspect the target Flutter version, Dart SDK constraint, app structure, package manager state, and test setup before editing.
• Prefer nearby project conventions for state management, routing, networking, localization, theming, and dependency injection.
• For layout errors, capture the primary Flutter exception before applying a generic constraint fix.
• For integration tests, add stable keys, use test entry points, and avoid hitting production APIs or accounts.
• For architecture changes, keep UI, ViewModel or logic, repositories, services, and models in clear layers rather than mixing data access into widgets.
• Run focused widget, integration, or flutter test validation before broad refactors.
• Redact screenshots, logs, API payloads, and test data before sharing output.

Use Cases

• Ask Codex to fix a RenderFlex overflowed or unbounded ListView error with a source-backed Flutter layout workflow.
• Use Claude Code to turn an MCP-explored checkout flow into a permanent Flutter integration test.
• Have Gemini CLI add widget tests for a UI component using WidgetTester.
• Ask an agent to add localization scaffolding with flutter_localizations, intl, generated ARB files, and l10n.yaml.
• Use an assistant to refactor a feature into Flutter's recommended layered architecture without mixing UI and data logic.

Source Review

• The README describes Flutter Agent Skills as maintained by the Flutter team.
• The README states the skills provide tailored instructions for happy-path Flutter app development workflows.
• The README says skills complement MCP by teaching agents how to use tools for a task.
• The install command uses npx skills add flutter/skills --skill '*' --agent universal --yes.
• The available skills list covers integration tests, widget previews, widget tests, architecture, responsive layouts, layout fixes, JSON serialization, declarative routing, localization, and HTTP.
• The integration-test skill includes MCP-assisted UI exploration and conversion into permanent integration tests.
• The layout skill documents common Flutter constraint errors and repair workflows.
• The license file identifies the repository as BSD-3-Clause.
