Can you list the main principles underlying clean architecture?

The main principles of clean architecture include:

• Separation of concerns: each layer is responsible for its part of the logic and does not depend on the implementation details of other layers.
• Dependencies point inward: upper levels (e.g., business logic) do not depend on lower levels (e.g., UI, database).
• Abstractions over details: implementation details (e.g., databases, frameworks) depend on abstractions, not vice versa.
• Framework independence: architecture should not depend on specific libraries or frameworks.
• Testability: business logic should be easily testable without dependence on external components.

In the context of Flutter, this helps build applications where UI, business logic, and data are clearly separated, making maintenance and scaling easier.
