Flutter vs Kotlin – Which Platform is Dominating the Market?

Gone are the days when cross-platform development meant the app would be built either using React Native or Flutter. Today, Kotlin has managed to enter the competition, amplifying the confusion of business owners between React Native vs Flutter vs Kotlin.

Earlier, both entrepreneurs and mobile app developers prefer to use React Native.

But as Flutter has matured and Kotlin became popular, businesses are now shifting from React Native to either one of these technologies.

We have already done the React Native vs Flutter comparison, and the latter has emerged as the winner. So, today we are going to make a Flutter vs Kotlin comparison to find out which technology you should prefer to build a cross-platform mobile app.

Why Flutter is an Excellent Choice?

Why Flutter is an Excellent Choice?

Released in 2015, Flutter is an open-source platform that had an intent to organize a marketplace for Google Fuchsia. It is a UI toolkit that enables developers to build beautiful applications for mobile, web, and desktop using a single codebase.

Following is a Sample of a Flutter Application

import ‘package:flutter/material.dart’;void main() => runApp(MyApp());class MyApp extends StatelessWidget {

   @override

   Widget build(BuildContext context) {

     return MaterialApp(

       title: ‘Welcome to Flutter’,

       home: Scaffold(

         appBar: AppBar(

           title: Text(‘Welcome to Flutter’),

         ),

         body: Center(

           child: Text(‘Hello World’),

         ),

       ),

     );

   }

 }

Google UI framework focuses on prevailing technological and market challenges. As a result of which Flutter became an ideal cross-platform app development framework within a very short time.

What is Kotlin Multiplatform?

What is Kotlin Multiplatform?

Developed by JetBrains, Kotlin is basically a general-purpose, open-source programming language. It is statistically typed as a ‘pragmatic’ platform for Java Virtual Machine.

Released in 2010 with a small project, its first release came in 2016. Generally speaking, the programming language is quite popular for building native mobile applications for Android.

Whereas Kotlin Multiplatform is an important feature of Kotlin that complies with the JVM bytecode, JavaScript, or LLVM code.  Like Flutter, Kotlin multi-platform itself is an SDK that allows you to reuse business logic by building applications for Android, iOS, Web, Desktop, and even helps in backend development in Java frameworks like Spring. 

Although the idea of investing in the Kotlin app development is new, it is surprisingly embraced by various companies. Let’s find out why?

Why Kotlin Multiplatform is Gaining Popularity?

Why Kotlin Multiplatform is Gaining Popularity?

1. An SDK, not Framework

When you plan to build your app in Kotlin, there is no need to shift the complete app. You can hire developers well versed with Kotlin to first work on just a single module, and then move ahead with the other modules if everything works well.

2. Simple Language

Kotlin has its syntax quite similar to the programming languages like Swift, Java, Groovy, and Scala, it is fairly simple to understand the language. 

3. Reuse of the Logic

This is not the only platform that allows separating UI and enterprise logic. Xamarin and React Native are other frameworks that also provide this kind of service. There is one thing that makes it different from others i.e. shared logic and libraries within the UI layer. 

This makes the Kotlin developers work together in the native surroundings:

  • Swift and XCode for iOS
  • JavaScript for the Internet
  • Kotlin
  • Android Studio

All this is done without utilizing any bridge in an extra native manner.

4. Native UI Expertise

Kotlin Multiplatform doesn’t demand any instructions for creating UI. The Kotlin developers can work on the design, appearance, and efficiency appliance similar to native.
