What This Skill Can Do

Concrete capabilities you get when you install this skill.

Design Flutter app architecture with clear presentation, domain, and data boundaries

Choose and apply state patterns such as local state, Riverpod, or Bloc based on workflow complexity

Integrate platform capabilities through safe plugin and platform-channel boundaries

Diagnose rebuild storms, memory spikes, startup latency, and binary-size regressions

Get Started

How to install and use this skill in your preferred environment.

Skills are designed for AI coding agents (Claude Code, Cursor, Windsurf) and IDE-based workflows where the agent can read files, run scripts, and act on your codebase.

Models & Context

Which AI models and context windows work best with this skill.

Recommended Models

Works well with Claude Sonnet or GPT-4o. Native plugin work benefits from models that can reason across Dart plus platform-specific Android and iOS concerns.

Context Window

SKILL.md is concise (~4KB). Fits in 32K context; cross-platform debugging with native snippets benefits from 64K+.

Pro tips for best results

1

Be specific

Include numbers — users, budget, RPS — so the skill can size the architecture.

2

Share constraints

Compliance needs, team size, and existing stack all improve the output.

3

Iterate

Start with a high-level design, then ask follow-ups for IaC, cost analysis, or security review.

4

Combine skills

Pair with companion skills below for end-to-end coverage.
