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

Some approaches to state management in Flutter can cause difficulties or inconveniences:

• setState in large widgets: Using setState to manage complex state in large widgets leads to re-rendering the entire tree, which reduces performance and complicates maintenance.

• Global singletons or global state: Storing state in global variables or singletons makes testing and scaling the application more difficult.

• Excessive use of Provider without clear structure: When many providers are used without a clear architecture, it becomes hard to understand where and how the state changes.

• Bloc without understanding: Using complex architectures like Bloc without a deep understanding can lead to excessive code and complexity.

• Lack of separation of UI and logic: Approaches where logic is tightly coupled with UI make maintenance and testing harder.

Overall, approaches that lead to:

• Difficulties in scaling
• Difficulties in testing
• Poor readability and maintainability of code

It is better to choose architectures with clear separation of responsibilities and predictable state management.
