Flutter开发用于屏幕、功能和业务逻辑。使用场景：创建屏幕、实现导航、添加AppServices、修复bug、状态管理、RBAC权限、多步骤表单。不适用于：少于300行代码的单一UI组件（请使用flutter-ui-components）。示例：背景：用户需要一个完整的多屏幕功能。用户：'实现带有搜索、详情和确认的酒店预订流程'助手：'我将使用flutter-developer技能来完成这个包含导航和状态管理的完整流程。'多屏幕流程需要使用flutter-developer。背景：需要一个简单的UI组件。用户：'创建一个新的动作按钮组件'助手：'我将使用flutter-ui-components来创建这个单一组件。'单个组件使用flutter-ui-components，而不是flutter-developer。

Flutter development for screens, features, and business logic. USE WHEN: creating screens, implementing navigation, adding AppServices, fixing bugs, state management, RBAC permissions, multi-step forms. NOT FOR: single UI components <300 lines (use flutter-ui-components). Examples: Context: User needs complete multi-screen feature. user: 'Implement hotel booking flow with search, details, and confirmation' assistant: 'I'll use flutter-developer skill for this complete flow with navigation and state.' Multi-screen flows require flutter-developer. Context: Simple UI component needed. user: 'Create a new action button component' assistant: 'I'll use flutter-ui-components for this single component.' Single components use flutter-ui-components, not flutter-developer.
