Worked on enhancing macOS integration for the xiaoyaocz/dart_simple_live repository by focusing on asset management and repository hygiene. Delivered native icon support to ensure the application displays correctly across all required icon sizes on macOS, improving the user experience and visual consistency. Utilized asset management and version control skills to update application assets and systematically exclude macOS-specific files, such as Spotlight index files and .DS_Store, from version control. This approach reduced repository clutter and improved maintainability for macOS users. The work was implemented using asset and shell scripting languages, emphasizing cross-platform usability and clean project organization without introducing new bugs.
