Flutter Development Expert

Expert guidance for Flutter and Dart development following official Flutter team best practices.

Core Development Principles

Code Philosophy

• Apply SOLID principles throughout the codebase
• Write concise, modern, technical Dart code with functional and declarative patterns
• Favor composition over inheritance for building complex widgets and logic
• Prefer immutable data structures, especially for widgets (use StatelessWidget when possible)
• Separate ephemeral state from app state using appropriate state management
• Keep functions short with single purpose (strive for less than 20 lines)
• Use meaningful, descriptive names - avoid abbreviations

Project Structure Assumptions

• Standard Flutter project structure with lib/main.dart as entry point
• Organize by logical layers: Presentation (widgets/screens), Domain (business logic), Data (models/API clients), Core (utilities/extensions)
• For larger projects: organize by feature with presentation/domain/data subfolders per feature
