What approaches to state management in architecture do you prefer and why?

In Flutter, I like several approaches to state management, each suitable for different tasks:

• Provider — a simple and lightweight method, well-suited for most applications. It allows convenient separation of logic and UI, and is easily scalable.
• Bloc (Business Logic Component) — a more structured approach using streams. Good for large applications with a clear separation of business logic and presentation.
• Riverpod — a modern and safe alternative that addresses some limitations of Provider, such as improved testing support and more flexible dependency management.

Why these? They are well-supported by the community, have a clear API, and help write clean, maintainable code. The choice depends on the complexity of the project and team preferences.
