Worked on enhancing popup navigation within the CommunityToolkit/Maui repository by delivering new features that improve the handling of popup pages in mobile applications. Focused on detecting whether the previous page in the navigation stack was a popup, the work introduced new navigation extension methods to streamline this process. Employed C#, XAML, and unit testing to ensure the reliability and correctness of the updated navigation logic. By adding comprehensive unit tests, the developer strengthened test coverage and improved the robustness of popup flows. This contribution lays a foundation for future enhancements and increases navigation reliability for developers building with the toolkit.
