React Native, Flutter, Ionic and Xamarin are the most popular cross-platform frameworks today. In some cases, developing your application with one of these frameworks might be a good alternative to a native approach since you need to create only one app that will work on multiple platforms. However, you should keep in mind that cross-platform frameworks are just the wrappers for native. Each framework provides different opportunities for an app developer, so which one is better depends on your needs.
