flutter-feature-analysis

name	flutter-feature-analysis
description	Use when assessing feasibility or complexity of a new Flutter feature before implementation. Especially when evaluating API requirements, state management approach, UI component availability, native dependencies, or effort estimation.

Feature Analysis Skill

Analysis Framework

1. Discovery

grep -r "<similar_feature>" lib/features/    # Find patterns
grep "<package>" pubspec.yaml                # Check dependencies
find lib -path "*/domain/models/*.dart"      # Review models

2. Complexity Assessment

Simple:

• Single API call, straightforward UI, minimal state
• Example: Display static model details
• State Management: Simple solution (Cubit, ChangeNotifier, GetxController)

Complex:

• Multiple API calls, state orchestration, complex business rules
• Example: Multi-step flow
• State Management: Robust solution (Bloc with events, StateNotifier, complex GetX)

3. Technical Checklist

• API endpoint exists?
• DTO/Model mapping needed?
• Repository pattern required?
• State management approach? (Check existing patterns in project)
• UI components available in design system?
• Native platform features needed?
• Accessibility considerations?
• Performance implications?

4. Dependencies

• Check pubspec.yaml for existing vs new packages
• Check native side: plugin/ios/, plugin/android/
