Why is it important to adhere to the principles of clean architecture when designing systems?

Principles of clean architecture are important because they ensure:

• Modularity and independence of components: each layer of the system is responsible for its own area, which simplifies maintenance and development.
• Testability: thanks to dependency separation and clear interfaces, it is easy to write and maintain unit tests.
• Flexibility and scalability: changes in one part of the system minimally affect others, making it easier to add new features.
• Code reuse: well-defined boundaries and dependencies allow components to be used in different projects.

For example, in a Flutter application, you can divide it into layers: UI, business logic, and data access. This approach helps avoid tight coupling and makes it easier to replace or update individual parts without global changes.
