Flutter vs Kotlin: What to Choose?

The debate is not new and even our internet is flooded with multiple articles regarding “Flutter vs Kotlin”. 

But no specific answer is given to the question, right?

Well, that’s why, you have stumbled upon the post to know the right difference between Flutter & Kotlin. 

Both mobile app development frameworks are incredibly popular when it comes to building scalable, responsive, and feature-rich apps. 

But as a rule of thumb, you cannot walk on two boats at a time. Thus, it is important to choose the right one for your app development project. 

In this post, we’ll discuss the ins and outs of Flutter vs. Kotlin to ensure you’ll make the right decision. 

Let’s dive in! 

Understanding Flutter: What is it?

Introduced by Google, Flutter is a popular cross-platform app development framework that enables developers to build solid and scalable mobile/web applications across various platforms. Backed by the Dart programming language, the framework enables developers to write code that can easily be compiled into native machine code across different platforms. One of the biggest highlights of Flutter is that it allows for the delivery of high-performance and native-like user experiences.

Speaking of its popularity, Flutter has garnered significant attention in a short span of time. And facts don’t lie!

Important Facts & Statistics Related to Flutter

Let’s take a look at some of the promising facts related to Flutter. 

  • Over 2 million developers have already utilized Flutter in 2023, and 500,000 of them use it every month.
  • Approximately 85% of Flutter developers simultaneously create applications for several platforms.
  • Approximately 90% of Flutter developers think that the framework enhances user functionality.

What are the Features & Benefits of Flutter?

Here is a list of the key features and benefits of Flutter.

  • Cross-Platform development

One of the key features and benefits of Flutter is that it facilitates cross-platform development, which allows apps to be developed for both the iOS and Android platforms using a single codebase. Because developers don’t have to build unique code for every platform, this saves time and effort.

  • Hot Reload

Another major feature and benefit of Flutter offers a hot reload functionality, which developers can update code in real-time and iterate more quickly.

  • Graphic Interface

Flutter, which is based on the Dart Programming Language, helps build a mobile app with a description of the graphic interface. Along with images, typefaces, and other elements, the work’s outcomes are included in the native program.

Apps based on Flutter

Here’s the list of the most popular apps that are built using Flutter:

  • Google Ads.
  • KlasterMe.
  • Reflectly.
  • Take Your Seat.
  • Xianyu by Alibaba.
  • Lunching.
  • Pairing
  • Postmuse.


Understanding Kotlin 

Whether you want to build Android apps, server-side apps, and much more, Kotlin is an ideal choice. It is a cross-platform, general-purpose, and open-source programming language that runs on JVM. Backed by Java’s virtual machine (JVM), the framework is compatible with all kinds of browsers, devices, and OS, making it a preferred option among developers of all kinds. The major highlight of the framework is that the apps built using Kotlin or with the help of Kotlin app development company can easily be used wherever Java works: the backend, the web, the desktop, and much more.

Some Quick Facts Related to Kotlin

  • A growing percentage—more than 10%—use Kotlin for mobile multiplatform development.
  • With a market share of 1.75% in 2024, Kotlin is ranked 13th on the PYPL ranking.

What are the Features and Benefits of Kotlin?

  • Native Performance

One of the biggest features and benefits of Kotlin is that it builds apps specifically for Android. This means that apps developed with Kotlin can achieve native performance on their respective platforms. Compared to cross-platform frameworks like Flutter, this can result in faster and more efficient apps.

  • Platform-specific APIs

Kotlin provides direct access to platform-specific APIs, which means developers can leverage the full capabilities of the underlying operating systems.

  • Mature Ecosystem

As compared to other frameworks available, Kotlin has been around for a longer time. There is no arguing with the fact that it has now earned a vast range of libraries, tools, and resources that help in the development. Developers can easily find solutions and address challenges, thanks to the extensive support. 

Apps based on Kotlin

Here is the list of the apps built using Kotlin. 

  • Postmates
  • Corda
  • Coursera
  • Evernote
  • Uber

Comparison Between Flutter vs. Kotlin: Know the Right Decision








Cross-platform (iOS, Android, Web, Desktop)

Primarily Android, but also supports multiplatform


A single codebase that facilitates faster development.

Native development for each platform offers platform-specific optimizations. 


Widget-based UI development with hot reload allows for rapid iteration and experimentation

XML-based UI development with Android Studio provides a structured approach to UI design


Generally fast and efficient, but may have larger app size due to framework overhead

Fast and optimized for Android, allows for fine-tuning of performance-critical apps

Learning Curve

Moderate, especially for those new to Dart, requires an understanding of reactive programming concepts

Moderate, especially for those new to Kotlin, familiarity with Java helps


Offers more flexibility in UI design and customization, suitable for custom UI requirements

Offers flexibility with native Android development, provides access to platform-specific APIs and features


Easier maintenance with a single codebase, updates and changes may apply across all platforms

Requires separate maintenance for each platform, updates need to be applied individually for Android and other platforms


Final Thoughts 

So, there you have it! Whether you are building a web app or a dedicated mobile app, Flutter and Kotlin are two of the popular frameworks to consider. But if you want to build an app that saves time and has built-in features, Flutter is an ideal choice! It offers a rapid development cycle, a single codebase for multiple platforms, and a rich set of pre-designed widgets. On the other hand, if you want to build a native Android app then Kotlin is a better choice.
