Write Flutter widgets (Flutter 3.x / Dart 3) that are simple, testable, and performance-focused. Use this skill whenever the user asks for a Flutter widget, screen, page, component, UI element, or any `.dart` file containing widgets — even if they don't say "skill". Also use when refactoring existing Flutter UI code, fixing rebuild/performance problems, or reviewing widget code. The skill enforces a strict ban on common LLM anti-patterns: `Widget _buildX()` methods, missing `const`, bloated `build()` bodies, and business logic mixed into widgets.

From the source SKILL.md

A skill for producing Flutter widgets that are simple, testable, and high-performance by default — and for refusing to produce widgets that are not.

What this skill does

Flutter Widget is a community-contributed Claude Code skill in the mobile sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/flutter-widget/ and loads when your prompt matches the skill's trigger.

When to invoke it: use when refactoring existing Flutter UI code, fixing rebuild/performance problems, or reviewing widget code. The skill enforces a strict ban on common LLM anti-patterns: `Widget _buildX()` methods, missing `const`, bloated `build()` bodies, and business logic mixed into widgets.
