This skill gives your agent a five-step Flutter workflow: setup, state, widgets, test and optimize. It uses flutter analyze, flutter test and DevTools profiling at each step, and keeps six reference files for Riverpod, Bloc, GoRouter, widget patterns, project structure and performance.

It triggers on widget development, Riverpod or Bloc state management, GoRouter navigation, platform-specific code and performance work. It is one of many skills in the jeffallan/claude-skills pack.

Good for

Flutter developers who want consistent state, routing and widget patterns
Teams choosing between Riverpod and Bloc
Developers chasing jank and extra rebuilds

Install flutter-expert

Claude Code

Copy this prompt.

Install the flutter-expert skill in Claude Code. Run this command:

/plugin marketplace add jeffallan/claude-skills
/plugin install fullstack-dev-skills@fullstack-dev-skills

Then check that it loaded and tell me how to use it.

Paste it into Claude Code. It shows the change and asks before running it.

Plugin route: adds the pack's 67 skills (the repo has 67) and its 9 workflow commands, such as /common-ground and /project:*, not only this skill. Restart Claude Code when prompted. Skills CLI route: the Quick Start says it installs skills only, without the slash commands; the --skill flag picks this one.

Watch out for

A fix step upgrades packages to major versions
The troubleshooting table suggests flutter pub upgrade --major-versions after a failed build. That can change many packages at once. Review pubspec.lock changes. github.com
The plugin route installs the whole pack
The plugin manifest describes 67 skills and 9 workflow commands. The repo has no hooks file or .mcp.json at its top level; each skill is a SKILL.md with reference files. github.com

Questions

What does the flutter-expert skill do?

It makes your agent write Flutter 3 code with a fixed workflow: Riverpod or Bloc for state, GoRouter for navigation, const-optimized widgets, tests, and profiling with DevTools.

How do I install it?

Use the install box on this page. It installs this skill alone. The pack README also documents a Claude Code plugin route that installs the whole pack of skills and workflow commands.

Riverpod or Bloc?

It supports both and loads a separate reference file for each. The Riverpod example in the SKILL.md is marked the correct pattern, and the Bloc reference calls Cubit the recommended choice for simpler logic.

Does it need its related skills?

No. The SKILL.md lists react-native-expert, test-master and fullstack-guardian as related skills, but nothing in it requires them.

Is it safe to run?

It runs flutter commands and edits your project files, and the troubleshooting table suggests upgrading dependencies to major versions. Work on a branch and review the diff. The Watch out list has more.
