To structure a Flutter project for clean architecture, organize code into a feature-first modular design with clear boundaries between core utilities, data, domain, and presentation layers using repository patterns.

The best way to organize a growing Flutter codebase is adopting a feature-first architecture, grouping independent features instead of technical file types to keep shared logic and dependencies maintainable.

Barrel files help manage imports in a Flutter application by creating consistent import strategies through hierarchical exports, resulting in cleaner centralized dependency management across modular features.

You should refactor your Flutter application into a modular architecture when adding large features or facing a disorganized codebase, establishing scalable feature-based architecture to restore maintainability.

Feature-based Flutter architecture requires no specific external dependencies or components, relying instead on layered architecture conventions, repository boundaries, and barrel exports to establish maintainable application organization.
