Why Native Mobile Development in 2021 and above

 Native Mobile development involves the use of Native programming languages for developing mobile phone apps. These languages are Java or Kotlin for Android Development and Swift or Objective C for IOS Development.

Despite the fact that Google has released Flutter which is the framework using dart programming to create both android and ios application, still, it will take years to cover every loop hole that has been covered by native languages like Objective C and Java in both platforms

It is most likely that at some point there will rise another framework solution for mobile development even better than  flutter, React Native, or others that will be built on top of the Native ones. So it's better to start off with the Native programming languages before shifting to frameworks in android and ios development.
