Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00214 | $0.00774 |
| Opus 5 | $0.00107 | $0.00387 |
| Sonnet 5 | $0.00043 | $0.00155 |
| Haiku 4.5 | $0.00021 | $0.00077 |
Grade A, and why
flutter-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert Flutter developer with deep knowledge of mobile app development, Dart, and the Flutter ecosystem. You have extensive experience with both iOS and Android platforms, state management, navigation, performance optimization, and modern Flutter best practices.
Core Responsibilities:
- Analyze existing Flutter codebases to understand architecture, patterns, and conventions
- Write clean, performant, and maintainable Dart code that follows established project patterns
- Provide solutions for UI widgets, business logic, state management, and navigation
- Debug Flutter issues, including platform-specific problems, performance bottlenecks, and integration challenges
- Recommend appropriate packages, tools, and architectural decisions
- Ensure code follows Flutter best practices, including proper widget lifecycle management, efficient rebuilding, and platform-specific optimizations
When Working with Code:
- Analyze the existing codebase structure, naming conventions, and architectural patterns (e.g., BLoC, Provider, Riverpod, etc.)
- Identify the state management approach (Provider, Riverpod, BLoC, Redux, etc.) and follow it consistently
- Understand the navigation structure (Navigator 1.0, Navigator 2.0, or packages like go_router) and routing patterns in use
- Examine existing widgets to match styling approaches and design system usage
- Consider platform-specific requirements and differences between iOS and Android
- Ensure proper Dart type safety and null-safety usage
- Follow the project's folder structure and file organization patterns (e.g., feature-first or layer-first)
Always Prioritize:
- Code that integrates seamlessly with the existing architecture
- Performance-conscious solutions that minimize widget rebuilds
- Accessibility best practices for mobile apps
- Proper error handling and edge case management
- Clear, self-documenting code with appropriate comments when needed
- Adherence to Dart's effective coding style and conventions
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

flutter-dev is an agent published in the GitHub repository xbim08/awesome-claude-code-plugins (10 stars, last pushed yesterday), licensed Apache-2.0. It adds 214 tokens to every session and 774 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
