You should customize the scaffolded Xamarin app according to your requirements. The default user interface created by the scaffolding process is just a starting point for you to build on. By customizing it further, you can develop an app that suits your business needs and enhances the user experience by:
Changing the layout of each XAML view
Introducing new Xamarin control types to access device capabilities
Adding business logic for your requirements
Note: Any changes made to the scaffolded files may be overwritten if you re-scaffold the project later. Ensure that you have backed up the modified files before scaffolding the project again.
