Overview

This skill is a Flutter and Dart expert that helps developers improve apps across widgets, state management, and platform integration. It enforces modern Flutter 3.x practices, Material 3 design, and null safety while adapting suggestions to your existing architecture. The goal is pragmatic, production-ready guidance that improves maintainability, performance, and platform behavior.

How this skill works

I analyze Dart and Flutter code to spot anti-patterns, naming issues, widget composition problems, and missing null-safety guarantees. I recommend concrete refactors (small focused widgets, const constructors, keys), architecture improvements (BLoC, clean layers), dependency injection with GetIt, and platform channel usage when needed. I also provide performance tuning tips (image caching, list optimizations, build minimization) and explain why each change matters.

When to use it

  • During code reviews to enforce Flutter best practices and consistency
  • When introducing or refactoring state management (BLoC/state separation)
  • When integrating platform APIs or building platform channels
  • To optimize UI performance, list rendering, or image handling
  • When preparing code for production: testing, error handling, and DI setup

Best practices

  • Prefer small, focused widgets and compose rather than large StatefulWidgets
  • Use const constructors and immutable models where possible to reduce rebuilds
  • Follow null-safety everywhere and prefer sound typing over dynamic types
  • Adopt clean architecture with BLoC for business logic and GetIt for dependency injection
  • Optimize lists with proper builders, caching images, and avoiding expensive work in build()
  • Follow platform-specific UI guidelines and use platform channels only when necessary

Example use cases

  • Review a screen that rebuilds excessively and get a step-by-step refactor to minimize rebuilds
  • Migrate app state from Provider to a BLoC-based clean architecture with DI setup
  • Design and implement a platform channel for native camera or sensor access with error handling
  • Audit app for Material 3 compliance, accessibility, and localization readiness
  • Improve list performance in a feed by applying caching, item keys, and pagination

FAQ

Do you enforce a single architecture style?

No. I adapt suggestions to the existing architecture while recommending clean, testable patterns like BLoC and DI when appropriate.

Can you help migrate to null safety or newer Flutter versions?

Yes. I provide concrete code changes, migration steps, and compatibility notes for moving to Flutter 3.x and sound null safety.
