Skill UI

This comprehensive guide provides an end-to-end solution for implementing Firebase Cloud Messaging (FCM) in Flutter applications. It covers platform-specific setup for iOS, Android, and Web, detailing how to handle messages in foreground, background, and terminated states. Key topics include managing notification permissions, handling token lifecycles, and implementing reliable cross-platform push notification logic.

A comprehensive guide on utilizing Firebase Remote Config within Flutter applications. Learn how to implement dynamic feature flags, execute A/B testing, manage remote parameter defaults, and fetch real-time configuration values. This skill allows developers to modify app behavior and user experiences without requiring an app store update, ensuring fast iteration and efficient product testing.

A comprehensive guide to structuring robust Flutter applications using industry-standard layered architecture (UI, Domain, Data). It details patterns like MVVM, Repository pattern, and Use Cases, ensuring clean separation of concerns, manageable state flow (unidirectional data flow), and testability. Ideal for scaffolding new, large-scale projects or refactoring legacy codebases.

Guides using ChangeNotifier with provider for Flutter state management, covering model creation, providing to the widget tree, consuming via Consumer and Provider.of, optimization practices, and testing notifications.

Diagnoses and explains fixes for Flutter runtime and layout errors such as RenderFlex overflow, unbounded constraints, scroll-controller conflicts, and inappropriate setState calls during build, helping developers resolve issues quickly.

This comprehensive guide details how to properly integrate and configure Firebase within Flutter applications. It covers initial setup using `flutterfire configure`, essential initialization in `main.dart`, handling platform-specific requirements, and advanced techniques for managing multiple app flavors (dev, staging, prod).

Guides building production-ready user interfaces with thoughtful component architecture, consistent spacing, typography, color, and accessibility standards while avoiding generic AI aesthetics and over-configured patterns.

Guides multi-round investigation of any GitHub repository, combining API queries, discovery searches, and deep dives to produce structured markdown reports with summaries, timelines, metrics tables, and Mermaid diagrams for executive-ready briefs.

Accelerates GitHub cloning, release/raw/archive downloads, and other resource access for Mainland China users by rewriting URLs through githubproxy.cc or fallback ghfast.top, with an optional URL converter script for quick adaptation.

This skill guides the complete Go performance measurement workflow. Learn how to write robust benchmarks using `b.Loop()`, run detailed tests with flags like `-benchmem` and `-cpuprofile`, interpret memory and CPU profiles, statistically compare performance changes, and document optimization results in git commits. It ensures deep, data-driven performance analysis for Go applications.

Guidance for building, extending, and reviewing production Go CLIs with Cobra+Viper: project layout, root command defaults, flag binding, validation, config layering, logging, and completion patterns for Unix-friendly tooling.

This skill provides comprehensive guidelines for writing clean, idiomatic, and maintainable Go code. It covers critical best practices for variable declaration, control flow structuring (e.g., early returns, switch statements), function design (e.g., parameter limits, context usage), and ensuring correct data structure initialization. Use this skill when writing new Go features, reviewing existing code for clarity, or establishing team coding standards.
