flutter/flutter-app-size

测量并减小 Flutter 应用包、APK 或 IPA 的大小。

flutter-app-size 是什么?

此技能用于分析和优化 Flutter 应用的构建产物大小,包括 APK、IPA 和应用包。它能帮助开发者识别哪些资源、库或代码模块占用了过多空间,并提供具体的优化建议,例如移除未使用的资源、启用代码混淆、压缩图片、使用延迟加载、分析依赖树等。该技能适用于所有 Flutter 项目的本地开发环境,通过解析构建命令的输出和文件层级来定位体积瓶颈。掌握此技能可有效减小应用下载大小,提升用户转化率,并符合应用商店的包体限制要求。

flutter/flutter-add-widget-preview

Adds interactive widget previews to the project using the previews.dart system. Use when creating new UI components or updating existing screens to ensure consistent design and interactive testing.

flutter/flutter-add-widget-test

Implement a component-level test using `WidgetTester` to verify UI rendering and user interactions (tapping, scrolling, entering text). Use when validating that a specific widget displays correct data and responds to events as expected.

flutter/flutter-animating-apps

Implements animated effects, transitions, and motion in a Flutter app. Use when adding visual feedback, shared element transitions, or physics-based animations.

flutter/flutter-animation

Add animated effects to your Flutter app

flutter/flutter-apply-architecture-best-practices

Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.

flutter/flutter-architecting-apps

Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.

flutter/flutter-architecture
