Maintainable Flutter architecture separates presentation, domain, and data concerns; uses repositories for data access; and picks state management and navigation patterns that match team skills and product complexity. No single architecture fits every project—this guide documents options and tradeoffs.
Large products may need formal ADRs, module boundaries, and platform-specific native modules documented separately.
Organize by feature or by layer with clear boundaries: UI/widgets in presentation, business rules in domain, and API/storage in data. Use repositories to abstract data sources and inject dependencies for testing.
Riverpod and Bloc are common for larger apps; Provider suits simpler cases; GetX offers convenience with different tradeoffs. Choose based on team experience, testability needs, and product complexity—not trends alone.
No. MVPs may use lighter structure; long-lived products with multiple developers benefit from stricter layering, testing, and modularization.
