Unused widgets

This rule identifies and reports widgets in the codebase that are not utilized anywhere within the application. Unused widgets contribute to code bloat, reduce maintainability, and can lead to confusion for developers. By removing these unused widgets, the codebase becomes cleaner, more efficient, and easier to navigate. Why This Matters: - Improves Maintainability: Reduces clutter and makes the codebase easier to understand. - Enhances Performance: Eliminates unnecessary components that could potentially consume resources. - Simplifies Refactoring: Facilitates smoother refactoring and updates by reducing the amount of code to consider. - Prevents Potential Bugs: Minimizes the risk of errors related to outdated or redundant code. How to Fix: Confirm that the flagged widget is indeed not used anywhere in the application. Remove the unused widgets from the codebase.
