Architecture
Clean Architecture, folder structure, and dependency injection for Flutter apps that need to survive past the first release — not theory, actual production folder trees.

Related Interview Questions
What is Clean Architecture and how does it apply to Flutter?
Clean Architecture separates an app into independent layers — typically presentation, domain, and data — where inner layers (business logic) never depend on outer layers (UI, frameworks, databases), so business rules can be tested and reused independently of Flutter itself.
What is the Repository pattern?
The Repository pattern puts a single abstraction in front of however data is actually fetched or stored — network, local cache, database — so the rest of the app talks to one consistent interface and doesn't care where the data comes from.
What is Dependency Injection and how is it used in Flutter?
Dependency Injection means a class receives its dependencies from the outside (via constructor or a container) instead of creating them itself, which decouples classes from concrete implementations and makes them easy to test with substitutes.
