Flutter vs Kotlin: Who Will Rule the Cross-platform App Market?

Flutter vs Kotlin: Who Will Rule the Cross-platform App 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.

The major difference between Flutter vs. Kotlin is that Flutter does come with some very valuable benefits like live-tracking,  modular architecture, third-party plugins, and a variety of widgets. As a result, it takes less time for app development. In contrast, Kotlin takes more time in the development process due to the absence of widgets. 


However, with Kotlin Multiplatform, you can build different multiplatform projects for numerous platforms, including desktop, web, and other native platforms.

No doubt, 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 {


   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.

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 appliances similar to native.

5. Scalability and Flexibility

The developers can scale up the applications without utilizing any virtual machine (VM). This makes it an ideal choice for creating an app where scalability and flexibility are necessary.


How does Kotlin Multiplatform work?

Kotlin multiplatform is a feature of the language that allows it to be used for more than just Android app development. It allows developers to share code, data, and business logic across a variety of platforms, including iOS, Web, Linux, macOS, Android, and the Java Virtual Machine (JVM).

Although the idea of investing in Kotlin app development for cross-platform is still new to the industry, it has been embraced by a number of well-known companies.


What is the Difference between Flutter & Kotlin?

Flutter and Kotlin, both platforms have the ability to create amazing applications. Still, there are many differences that we will be discussing below:

1. Popularity

Kotlin and Flutter both are open source platforms giving free access to everyone. This is one of the reasons why developers have a lot of curiosity about working on these platforms. Flutter is gaining more popularity than Kotlin and it can clearly be depicted from the GitHub presence. 

This clearly depicts that Flutter gets an enormous momentum available in the market when compared to Kotlin. 


2. Performance


The biggest benefit of using Flutter is that it gives the hot reload functionality. This feature makes it easy for the users to make different changes in the backend, and depict the difference in front-end concurrently. This ensures if the element and design are perfect, in case they are not, you can make the changes accordingly. Kotlin: Using Kotlin multi-platform allows the developers to compile the code explicitly in the same format, just like the targeted platforms. Therefore, it is a reliable platform for good performance in their native counterparts.


3. UI Experience


When you invest in Flutter app development, you get the opportunity to take the help of various widgets available. This further helps in creating mobility solution ions in a quick, effective, and customized manner.  Kotlin: In Kotlin app development, the developer doesn’t have to follow any kind of instructions for creating the UI, quite similar to the native apps.


4. Programming Language


This cross-platform app development framework takes the help of the Dart programming language. The language was introduced by Google in 2011. The syntax of Dart is quite reliable, easy to understand and learn.  One of the reasons is because it manages to support the object-oriented elements. The developers can access Dart as there is massive follow documentation available on the official website of Dart.


This is a general-purpose and statically typed programming language that helps to interoperate completely with Java. It is quite similar to Java and targets JavaScript, Native, and Java Virtual Machine.


5. Pricing



The open-source platform, Flutter, and Dart are both free to use platforms. This helps in empowering the developers to view:

  • Documentation

  • Post queries in the development forum

  • Learn and implement code

When you are considering the backend development services, Kotlin is one such platform that has an advantage over the ones that are in the market. Although Flutter operates with Firebase, which is an efficient Backend as a Service Platform securing backend opportunities, Kotlin allows developers to create the backend code. 


7. Integration


Flutter offers the functionality of creating an app and is compatible with both iOS and Android platforms with less code. This eventually makes Flutter the ideal option for MVP development while creating a prototype. You should test the waters beforehand.


The multi-platform framework is within the native ecosystem. The hired mobile developers can operate the same tools and libraries that they use during native development. This involves Jetpack Compose and SwiftUI. This clearly depicts that they require third-party libraries and tools to bridge combinations with the native environment. 


8. Community


Flutter is a platform that is constantly flourishing in the marketplace. The Flutter community is also increasing simultaneously. 


Google is developing itself to become Kotlin-oriented and this is one of the reasons why mobile app developers are getting inclined towards it.
