Behavior

Current Behavior: The project contains several linting warnings including:

• Unnecessary use of print() in production code.
• Missing const constructors for immutable widgets.
• Unused imports and unused local variables in controllers.
• Unnecessary Container wrappers that bloat the widget tree.

Expected Behavior: The codebase should be clean, following Flutter best practices, with no linting warnings in the "Problems" tab of the IDE. This ensures better performance and cleaner production logs.
