Kotlin Vs Flutter

With the earth moving more and more towards and getting firmly ensconced in the digital edge, we just cannot think without our mobiles, android mobile to be precise and the relevant apps. In fact, in every aspect of life apps play a stellar role in regulating it. The Apps do not fall from heaven and it is here that cross-platform app development and android app development play a decisive role. With almost every day newer apps are being launched adding to the comfort of the end-users.

Android App Development: Poised for Huge Leaps

It can, therefore, be prudently said that android app development is poised for giant leaps forward. An app developer today has the emancipation to use one single code to develop an app for multiple platforms courtesy cross-platform app development. This helps in developing the app for both android and iOS at a lesser operating cost.

Not long ago, the app developers worked with Flutter or React Native to develop an app until Kotlin came into the scene. App developers, till Kotlin arrived, were depending on Flutter or React Native for Android and iOS but the scenario has changed dramatically now.

Since its launch, Kotlin has made deep inroads into the territories of the competitors rapidly and a study by App Brains reveals that almost 82000 apps are using Kotlin. At the moment the platform is just preceded by JAVA. Big names like Samsung Experience, MS Word and Huawei video player use Kotlin.

Jetbrains had developed Kotlin. It is one of the most reliable platforms and the language used is easily understandable with minimum system failure and hassles.

Flutter mobile app development since its inception in 2015 was very popular and big corporations like Alibaba, New York Times, eBay, Groupon and Square have been using it constantly. Kotlin has an additional feature called Kotlin multi platform.


Now let’s look at the evaluation between Kotlin and Flutter below–





More Popular Less Popular
Use Dart Programming Language Use JVM, JavaScript & Native
Free &  Open Source Free &  Open Source
Excellent Speed Better in Security syntax & compatibility
Operating & Development Cost Low Operating & Development Cost quite High


Performance –

Both Kotlin and Flutter mobile app development is equally superb with some distinctions. Kotlin because of its multiplatform can compile the codes and customize it to the best satisfaction of its users as good as the Native apps. Flutter allows reloading functionality thus giving a choice of selection if different elements are performing okay.

Language –

The basic advantage of Kotlin is that its programming language is quite similar to Java and developers who have worked with JAVA find it much easier to work. On the other hand, Flutter uses Dart from Google. Although it is rarely used it is easier to understand and operate.

Price and testing –

Both Kotlin and Flutter are free of cost but the real difference occurs in testing support. While Kotlin tends to give more support on backend development, Flutter works on wider testing features.

UI support –

Kotlin multi-platform has a unique distinction of lending a freehand to the UI developer to make an app without restrictions and make a truly customized app. On the other hand, one can take the help of widgets if one is working with Flutter. This also helps in customized solutions.

Pros and cons of Kotlin


    • Since Kotlin is an SDK and not a framework, therefore, it is not necessary to shift the complete app to the platform. One can start working even with a single feature.
    • As Kotlin bears resemblance to Scala and Swift, it is easier to learn it and design a cross-platform app by using multi-frame.
    • Since UI creation is not restricted one has the freedom to work on any aspect of the app.


    • Very few libraries are in hand right now as Kotlin is still a fledgeling. Once Date TimeLibrary comes situation will improve,
    • Development cost is quite high which eventually will be dearer in the long run.
    • App developers must be spruced up to know each platform and API to handle Kotlin better.

Pros and Cons of Flutter


    • Operating cost and development charges are significantly lower because of the usage of native-like apps with single based code.
    • Hot reload functionality of Flutter mobile app development is a very important proposition of why the big brands go in for Flutter. Front end and back end developments are streamlined so that the apps perform much better.
    • Due to numerous widgets, Flutter can provide customised facilities to its usrs.
    • As Flutter helps in developing apps for both Android and iOS in a minimum period, it is thus good for MVP development.


      • The language used, Dart is still not familiar with all the app developers and this is quite a hindrance.
      • The framework size is very big and therefore the apps are much bigger in sizes which is detrimental in app development today.


Takeaway — Kotlin vs Flutter which one to choose–

Both Kotlin and Flutter have their pros and cons as discussed and Kotlin has a better market share. It is totally up to the app developers to pick and choose as to which one will be better for them depending on the ground realities. Kotlin because of its SDK properties one can even work with a single feature and offers an excellent UI experience. On the other hand, because of the lower cost and hot reload functionality is a better option for many.
