This comprehensive guide details the implementation of Firebase In-App Messaging within Flutter applications. It covers setup, programmatic message triggering and suppression during critical flows (like payments), and essential privacy controls for GDPR compliance. Learn best practices for testing campaigns, utilizing A/B testing, and managing the full lifecycle of in-app message campaigns.

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.

Guides integrating Firebase Cloud Storage with Flutter apps, covering setup, uploads/downloads, metadata, error handling, and security best practices for file management workflows.

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.

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).

A comprehensive guide for developing robust, Unix-native Command Line Interfaces (CLIs) using Go. It details best practices for command structure, flag handling, configuration layering (Viper), and argument validation using Cobra. Learn how to build, extend, and review professional-grade Go tools that behave predictably in shell environments.

This comprehensive guide covers Dependency Injection (DI) patterns specifically for Golang. It explains why DI is crucial for building testable, loosely coupled, and maintainable services. The skill compares manual constructor injection for small projects with advanced DI libraries (like google/wire, uber-go/dig) for complex architectures, focusing on best practices such as interface-based design and managing service lifecycles.

This skill provides comprehensive linting and static analysis for Go projects using golangci-lint. It enforces numerous best practices, checks for common errors, manages configurations via `.golangci.yml`, and supports auto-fixing. Use it during the entire development lifecycle, including setting up CI/CD pipelines, running pre-commit checks, or refactoring large, legacy Go codebases to ensure high code quality and maintain security standards.

A comprehensive skill for engineering high-quality, observable Go services. It guides best practices across five key signals: structured logging (slog), Prometheus metrics, OpenTelemetry tracing, continuous profiling (pprof), and RUM. Use this when instrumenting new features, reviewing PRs, or auditing entire codebases to ensure systems are fully measurable for reliable diagnosis and alerting.

This skill acts as an expert guide for the Go ecosystem, recommending production-ready libraries and frameworks. It follows best practices by prioritizing the standard library first. Use it when you need to compare alternatives, select the best library for a specific task, or add a new dependency to your Go project.

A comprehensive guide for structuring, organizing, and initializing Go projects. It covers architectural decisions (Clean, Hexagonal, DDD), best practices for directory layouts (CLI, Service, Library, Monorepo), mandatory naming conventions, and adhering to 12-Factor App principles. Use this when starting a new Go service, refactoring large codebases, or setting up a complex monorepo.
