Can you name the main principles on which good programming is built?

The main principles of good programming include:

• Code readability: code should be understandable to other developers, using clear variable and function names.
• Reusability: avoid code duplication, extract repeating parts into functions or classes.
• Modularity: break the program into independent and logically complete parts.
• Maintainability: code should be easy to modify and extend without risking breaking existing functionality.
• Testability: write code that can be easily covered by tests.
• Single Responsibility Principle (SRP): each module or class should have one responsibility.
• Use of design patterns: apply proven solutions for common problems.

In the context of Flutter, it is also important to monitor effective state management and UI performance optimization.
