1. The Architecture Rabbit Hole
When you start studying software engineering theory, you inevitably encounter Uncle Bob's Clean Architecture diagrams. Concentric circles, entities, use cases, interface adapters, repositories, presenters, and data sources.
It looks authoritative, academic, and deeply professional. So you decide to apply it to your new personal project: a simple recipe bookmarking app.
Three days later, you find yourself creating:
domain/entities/recipe.dartdomain/usecases/get_recipes_usecase.dartdomain/repositories/recipe_repository.dartdata/models/recipe_model.dartdata/datasources/recipe_local_data_source.dartdata/datasources/recipe_remote_data_source.dartdata/repositories/recipe_repository_impl.dartpresentation/controllers/recipe_controller.dartpresentation/views/recipe_page.dart
You have written nine files, mapped the same four fields across three different class conversions, and you haven't even written the code to show a picture of a pancake yet.
The Cost of Premature Abstraction
Clean Architecture was invented to solve real problems in large enterprise software: teams of fifty engineers working on the same codebase, swapping out database vendors without touching business rules, and writing automated unit tests for complex regulatory calculations.
If you are a solo developer building an MVP or a personal mobile application, copying enterprise patterns blindly creates massive friction:
- Every tiny feature requires modifying six files.
- Renaming a single field takes twenty minutes of boilerplate updates.
- Refactoring becomes so exhausting that you stop experimenting with new ideas.
What I Keep (The Pragmatic Middle Ground)
I do not reject clean architecture entirely. What I do is prune away the ceremonial fat and keep the three principles that actually save my sanity:
- Separation of Presentation and Data: Keep API calls and database queries completely out of your UI widgets. A widget should only display data and dispatch user actions.
- Repository Pattern: Create a single repository interface for each feature (like
AuthRepositoryorMealRepository). If you switch from local JSON mock data to a live Supabase backend, only the repository implementation changes, while your UI code stays untouched. - Plain Data Models: Use simple immutable data classes with
fromJsonandtoJsonmethods.
Architecture should serve you, not the other way around. If your architecture is slowing down your ability to ship working software, it is not clean: it is just heavy.
