Is Flutter likely to replace Java for Android app development?

by Ronak Patel CEO

Probably No! Java has been into the market from more than a decade and has been the first choice for the developers when it comes to developing an Android App. However, Flutter is neither bad anyway! Flutter is like something extraordinary, loved and adopted by many developers. We will be discussing the Flutter, Java from the very beginning.



Java is a fully class-based as well as an object-oriented programming language which is owned by Oracle. More than 3 Million devices are running in Java. Java processes on platforms such as Windows, Mac, Linux, etc. Java was built with five primary goals:

  • Portable
  • Secured
  • Excellent speed while Execution
  • Simple Programming language
  • Interpreted & dynamic


After the establishment of JIT(Just-in-time) compiler in 1997-98, the speed of Java has remarkably improved to a considerable extent. However, JIT compiler also absorbs much more memory in the programs than those written in C & C++.



After a long wait, Flutter is Finally out! Google has started the development process of Flutter from 2015, and since that the beta versions were being rolled out. Google has worked hard enough to provide a better platform for creating mobile apps. With the use of Flutter, developers can create native apps for both iOS & Android in an individual codebase.  In other words, you can write code for an app and can gain two versions from that!

Flutter is open source development toolkit based on Dart programming language. Google develops both of the above toolkit and language. Dart can be compiled into the JS & accordingly, runs on the browser, which can be helpful for the web developer.


  • Enables developers to build Android and iOS applications at the same time
  • Hot reloading fastens up the coding and prototyping speed
  • No issues or problems regarding compatibility( Android devices above 4.1)
  • Both Flutter and Dart have built-in support for unit testing
  • Flutter provides exceptional support for Text with its Mobile 2D rendering engine & in terms of performance; it is massively optimized.



  • Size of the files are bigger due to built-in widgets and not platform widgets
  • Flutter creates the User Interface on its custom way; it doesn’t create native components.
  • Libraries & support – impressive, but still not so rich as for the native development

As we have mentioned above, that Flutter uses Dart programming language. So here's a comparison of Java and Dart programming language.

Differences between Java and Flutter

  • One of the biggest most significant troubles for the Java Developers is SDK libraries. On the other hand, Dart comes along with the future class, and an SDK devised around it. Dart can perform anything from scratch.
  • You can create substantial web applications in Dart
  • The Learning curve for Java is better than Dart
  • When it comes to performance, Dart executes better than Java; which is also a compiled language
  • The License of Java is based on GPLv3, whereas Dart is BSD license based.           
  • There are not more differences when it comes to the syntax of Dart and Java.
  • Java was developed by James Gosling and Dart by Google
  • James Gosling developed Java and Google developed Dart.

There are many developers and companies who have adopted and are working on Flutter App Development. Hence, Java is still a basic feature of Android Studio, which is massively used among Android Developers.
