Structure your Flutter app with a lib/ directory containing services, models, screens, and widgets. Use the http package for API calls through a centralized ApiService with error handling, define models with fromJson factories, and configure environment variables via --dart-define flags following Flutter lint rules.

Implement an ApiService class using the http package that centralizes all API calls with error handling. Create corresponding model classes with fromJson factory constructors to deserialize API responses, ensuring type safety and consistent error management across your app.

Define environment variables in Flutter using the --dart-define flag at build time. Access them via String.fromEnvironment() in your code, then pass them to your ApiService for dynamic endpoint and configuration management without hardcoding sensitive values.

Yes, use StatefulWidget for screens that need to manage API calls and async data fetching. Follow the pattern of triggering API requests in initState or lifecycle methods, updating state with responses, and rebuilding the UI to reflect loaded data or error states.

Yes, create reusable widgets and extract your API logic into service classes. This approach reduces duplication, centralizes error handling, and makes your codebase maintainable as you apply consistent patterns across screens and features.

Embedding API logic in widgets creates tight coupling, duplicates error handling code, and makes testing difficult. A dedicated ApiService decouples business logic from UI, enabling easier mocking in tests and consistent behavior across your app.
