What is flutter-reviewer?

A reviewer for Flutter and Dart code that checks widget redraws, state management, performance, accessibility, and application structure. Flutter is a toolkit for building mobile interfaces from Dart code.

Use it after editing Flutter or Dart files to review widgets, app state, performance, accessibility, and structure.

It helps find slow screens, confusing state handling, inaccessible controls, unnecessary widget rebuilds, and crossed architecture boundaries.

flutter-reviewer — Agent for Claude Code by leandrosilvaferreira

Install

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.

Clone the repo

git clone --depth 1 https://github.com/leandrosilvaferreira/claude-plugins-registry

Made for: Claude Code.

Or install aia-harness, the plugin that ships this one along with the rest of its 97 skills, 27 commands, 50 agents.

Token cost

What it costs to keep this loaded

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 5.1	$0.00046	$0.03170
Opus 5.5	$0.00018	$0.01268
Sonnet 5.5	$0.00009	$0.00634
Haiku 4.5	$0.00005	$0.00317

Security

Grade A, and why

flutter-reviewer 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 19d ago.

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.

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.
