Flutter Vs Kotlin, Which Framework to Choose for Your Next Project?

Cross-platform mobile app development is becoming increasingly popular, and there are no reasons to doubt its effectiveness. There was a time when building an app with React Native and Flutter was considered as a synonym. Perhaps, these two frameworks rely upon business enthusiasts and mobile app development organizations to establish a cost-effective presence on Android and iOS. However, now that Kotlin has grown and entered the battle. Everyone is wondering who will be the ultimate cross-platform application industry dictator. Moreover, you can also consult with the mobile app developers to know which is the best framework to choose.

We’ll go through the Kotlin and Flutter comparison in detail in this article and assist you in determining the best solution for your cross-platform programming and development requirements. So, which framework should you choose to create cross-platform apps?.

What is Kotlin Multiplatform?

Kotlin multiplatform is an additional feature of the language that allows it to be used for more than just Android app development. It enables developers to share code, data, and business logic across several platforms, including iOS, Web, Linux, macOS, Android, and the Java Virtual Machine (JVM). So, to enjoy the features of Kotlin Multiplatform, get Mobile app development services.

What is the Flutter User Interface Framework?

Flutter is a Google-developed free and open-source mobile user interface development framework. To put it another way, Flutter allows you to create your own mobile application from a single array of code. It allows you to create iOS and Android apps using a single programming language and codebase.

Consider the following facets for comparing the Kotlin Multi Platform or Flutter?

Do you want to develop your mobile app? Are you confused about picking the one framework? We have shortlisted the prime factors that can help you decide on a particular framework.

Popularity on the market

Do you know Kotlin and flutter are open-source and free-to-use programming languages? As a result, mobile app developers are showing interest in collaborating with both. In comparison to Kotlin, the popularity of the Flutter is skyrocketing as per the Google trends. Similarly, when comparing Kotlin and Flutter on GitHub, the former has 28.3K stars and 3.29K forks, while the latter has 69.5K stars and 8.11 forks. Indeed, Flutter is gaining a lot of traction in the market as compared to Kotlin.

Curve of Learning

When we talk about the learning curve of the Flutter or Kotlin native battle, the latter unquestionably wins. The prime reason is that it is compatible with Google and Java. And when we discuss Kotlin, though the situation is a little different. Moreover, when we compare the Kotlin multi-platform with Flutter, it is new and has new resources available on the market. 


Do you know that Flutter language allows developers to use the same language for layout and backend? Moreover, it helps in improving the animation speed. However, in terms of the market share, Flutter is still a long way behind Kotlin. The main reason is that Kotlin code compiles in the same format as the platform in question. So, if you are thinking which is superior on the basis of execution, the answer is both. The latter is the winner of this Flutter or Kotlin showdown.

Third-Party Libraries and Tools Integration

Rather than creating its own platform ecosystem, Kotlin multi-platform works inside existing ones. Hence, mobile app developers can use the same tools and frameworks they used for native development, such as Jetpack Compose and SwiftUI. Moreover, the professionals do not need to rely on third-party libraries and tools to connect to the native environment. Nevertheless, it is essential in the case of the Flutter cross-platform SDK, as it is primarily a user interface development tool.

Concentrate on a variety of platforms

With Flutter, you can develop mobile applications for (Android and iOS). It can not be used to make an appearance on tvOS, Android Auto, CarOS, or WatchOS. Whereas, in Kotlin Multiplatform, there is no such limitation. It is used to create apps for devices and platforms other than mobile. As a result, using Kotlin multiplatform for mobile app development services is a great option to launch the app idea on every imaginable platform and device.

Speed of Coding

When it comes to coding speed, Kotlin falls behind Flutter. Kotlin code development takes roughly 15% to 20% longer than Java code development. In Flutter, it is quite the opposite because of the hot reload capability, the app development is 30 to 50 percent faster. Furthermore, Flutter makes it simple to change your code and see the results in real-time. So, when it comes to coding speed, Flutter has a distinct advantage.


It’s important to remember that users must perceive the cross-platform app as native. In another way, it represents the fact that the platform is created for the same platform. However, a cross-platform App will cause the UI elements to slow down. When you use Flutter to create an app, you’ll be able to employ a variety of widgets.

Community Support and Documentation

When we compare the Kotlin multi-platform with Flutter, it is still in its early stage and is currently in Beta. Hence, the documentation and community support for the latter lag behind that of the former. However, when the multiplatform gets established, it is expected that documentation and community strength will improve. Further, boosting everyone to use Kotlin for Cross-platform development. We’ve now seen how Flutter and Kotlin vary from several angles. To decide, it is necessary to understand the benefits and drawbacks of each option.

Who Will Win the Battle of Cross-Platform Development?

Both Kotlin multiplatform and Flutter are dependable, strive to shorten the time it takes to establish a presence on both Android and iOS platforms, and are Google-supported. They are giving each other a cutthroat competition and are becoming more competitive with each release. In this case, consult with mobile app developers and analyze your cross-platform app requirements and priorities to identify which is best – Kotlin or Flutter.

Wrapping Up

On the whole, we have discussed the points that can help you in deciding a framework for mobile app development. Otherwise, you can contact mobile app developers to create your application. In fact, the professionals will ensure your application is bug-free and has a unique UI.
