So what’s the most important decision you have to make while developing an app?
Hands down, it’s choosing the right technology! After all, it is responsible for how your app will look and feel.
Recently, cross-platform apps have gained more popularity and preference for their native-like experience and low-cost development. As a result, Flutter Vs. Kotlin has become a famous debate.
Gone are the times when by reading the word cross-platform, only React Native would come to the readers’ mind. With Google’s & Jetbrains’ backing, Flutter & Kotlin have gained an individual space in the app development market. Both technologies are still young and growing and thus proving to have the potential of ruling the future of mobile app development. This has initiated and also continues to add more fire to the Flutter Vs Kotlin debate.
Flutter Vs Kotlin: Basic Details
Flutter & Kotlin are cross-platform SDKs that allow you to create native-like mobile applications with only one codebase. In simple words, by single coding, you can have an app for iOS and Android.
Released in December 2018, Flutter is Google’s free and open-source UI SDK.
It’s a specialized software development kit (SDK), which provides a collection of tools for indigenous assistance in app development. It uses the Dart programming language, and there are tools for compiling the source codes into native machine codes. Along with this, it provides a collection of reusable UI elements, including buttons, text inputs, and sliders. It helps in personalizing the app, ensuring that the idea is realized as per the client’s vision.
On the other hand, Kotlin Multiplatform, an SDK released in 2020 by Jetbrains (Alpha), leveraged the capabilities of Native Kotlin to build cross-platform apps.
Differences Between Flutter and Kotlin Multiplatform
Various Parameters For Comparing Flutter Vs Kotlin
So by now, you must have the idea of Flutter & Kotlin individually. So it’s time to take a deeper dive into this debate. In this segment, you’ll witness a detailed discussion of diverse parameters.
Flutter provides the option of using the same language in the front-end and backend, which improves the speed and ensures higher performance. This also leads to hot reloading functionality, allowing developers to make changes in the code that are reflected right away in the mobile app, without even reinstalling it.
Whereas Kotlin’s performance is concerned, it organizes the code according to the targeted platform’s format. This sheer fact makes it far easy to customize and provides higher performance.
With both of them having unique advantages, it is understandable why Kotlin Vs Flutter’s performance is always a hot debate.
Flutter was primarily formed as an SDK to support UI development, so this is its strongest point. It is also known for providing widgets. These widgets shorten the development time and provide a mobile app solution that’s customized, quick, and efficient.
Whereas Kotlin Multiplatform provides complete freedom to develop a unique and creative app based on developer’s skills. It doesn’t have any restrictions or pre-conceived guidelines. So, developers have complete control over the app’s appearance and conduct.
Many do not consider popularity as an important parameter. But don’t you agree that popularity speaks about user favourability, developer favourability, and brand preference.
While we are writing this, on Github:
Also, as per research conducted to observe which SDKs software developers used throughout 2019 & 2020, Flutter experienced growth from 30% to 39%. While Kotlin Multiplatform didn’t even reach the alpha stage in 2019, and as it did in 2020, it was used by 2% of software developers throughout the year. Also, as popularity is being discussed, it is to be duly noted that overall Kotlin’s popularity can surpass that of Flutter anyday.
Being a cross-platform SDK, Flutter provides easy integration of third-party UI development tools.
While in Kotlin Multiplatform, the development is being done in the native ecosystem. So rather than making a new one, app developers can deploy the same libraries and third-party tools. These include SwiftUI, Jetpack Compose, and all the others used in native development.
Due to the backing of Google, for writing backend codes, Flutter uses firebase. It is an effective BaaS (Backend-as-a-Service) platform.
Kotlin Multiplatform allows developers to write backend code, hence providing them with more freedom.

Advantages Of Using Flutter
With the detailed comparison between Kotlin and. Flutter, now it’s time to have a glance over the salient benefits of Flutter.
As we mentioned above, this feature allows the developer to make changes in the code which are reflected simultaneously in the mobile app. This helps developers in knowing if a particular change is going well with other app components or not. Also, this is a significant point of difference in comparison for Flutter and Kotlin.
It’s possible because of the widgets discussed above. They make app development a far more creative experience for developers and allow the resultant app to be tailormade. This even fastens the process.
Being a cross-platform technology for iOS & Android, Flutter app development requires lesser money and time as well. This makes it the best option for MVP & Prototype so the investor can see how the idea will turn out and test it in the market while also using it to attract funding.
This point doesn’t make many features in the Flutter versus Kotlin debate but has significant importance. Flutter apps are known to have a fluid and fast UI, which is possible because of Skia Graphics Library. The UI gets redrawn whenever view changes when combined with GPU, Flutter UI gives a smoother and faster experience.
Advantages Of Kotlin Multiplatform
The entire development community knows the benefits of Kotlin (programming language) and Kotlin Native development. But here are the listed benefits of Kotlin Multiplatform development as a cross-platform.
This is probably the most important benefit for Kotlin Multiplatform. Unlike its predecessors, it isn’t just a framework but a software development kit (SDK). So in the case of existing apps, the developers need to add a module or migrate a small part to assess the project’s viability. This has helped Kotlin in eliminating the biggest risk concerned while migrating/moving to a new codebase. As the app development can start from a single component, the developer can test the project first on that particular component rather than invest in the entire development and test it later.
The syntax of Kotlin is similar to other programming languages like Java and Swift. This makes it easier for the developers to adapt to it as they don’t need to learn the same from the start. This point also has significant importance In the debate of these SDKs’ programming language, Dart vs Kotlin.
We know that Kotlin Multiplatform isn’t the first cross-platform technology to reuse business logic, even Xamarin and React Native do. What makes it better is that it employs the shared logic and libraries below the UI layer. Now, combining this with its feature of compiling code according to the targeted platform. It ensures that the resultant app provides the level of performance close to native app development.
With Kotlin Multiplatform, developers can scale up the app development without using the VM (Virtual Machine). Thus it offers enhanced scalability and flexibility.
Kotlin vs Flutter: Which One is Right for your Business?
All types of technologies are made for easing the work of developers. Whether it’s React Native, Xamarin, Flutter, or Kotlin Multiplatform. But you have to choose one to move forward with development, don’t you?
So, choose Flutter if you are looking to build MVP for testing your idea and attracting funding. With End-to-end development, it provides the option of cost-effective and short timeline development.
If you are looking for enhanced and tailormade UI, higher adaptability of business logic in apps, and want to mirror experience with native apps, choose Kotlin Multiplatform.
