How kavinrajmani/countries_app works
Countries App is a Flutter app for browsing country information, with search, region filtering, detail views, favorites, and light/dark themes documented in the README. The likely user workflow begins at the app entry point, moves through the country list and optional detail or favorites views, and uses country data and preferences services. Dart implementation excerpts were not provided, so app-level wiring is shown as unverified dashed relationships; native runner files are platform launch scaffolding, not the product workflow.
