Flutter vs. Kotlin 2022 – Which is Better?

The development of cross-platform apps is a popular alternative to native app development, and for good reasons, including quick time-to-market, lower costs, and a single codebase for numerous platforms.

As cross-platform development frameworks and technologies are increasingly becoming popular, people are also increasingly discussing frameworks to choose the appropriate one at the right moment.

This article will put two leading cross-platform development frameworks under the microscope for an in-depth comparison: Flutter vs. Kotlin 2022.

The Pros and Cons of Flutter

Flutter is a user interface toolkit developed by Google for creating natively built, appealing, and feature-rich mobile, web, and desktop programs. One of the fastest-growing open-source communities is Flutter. Developers may develop apps for Android, iOS, Linux, Windows, Mac, Google Fuchsia, and you may use a front-end codebase.


It is only right to see what each can offer before deciding who will win in the Kotlin vs. Flutter comparison. With that, here are the major advantages of using Flutter.

  • Stateful Hot Reload speeds up app development;
  • Widget customization;
  • Declarative and Expressive user interfaces;
  • Native performance; and
  • Cost and time savings.


The Flutter app development framework, however, is not without its disadvantages.

  • Large file sizes;
  • Performance concerns on iOS; and
  • A lack of third-party libraries and integrations.

The Pros and Cons of Kotlin

JetBrains’ Kotlin is a general-purpose programming language. It works hand-in-hand with Java. Moreover, it is Google’s preferred programming language for Android app development. Notably, after Google announced first-class support for Kotlin on Android, it immediately gained popularity.


To get a fair view of the Flutter vs. Kotlin 2022 comparison, here are the major advantages of using Kotlin:

  • Completely compatible with Java;
  • Code that is concise, secure, and dependable;
  • Easy maintenance of code;
  • Faster time-to-market deployment;
  • Simple learning curve; and
  • Native-like Performance.


Just like Flutter, Kotlin is not without disadvantages:

  • Less Compilation Speed than Java; and
  • Significantly Fewer Kotlin experts.

Flutter vs. Kotlin 2022: A side-by-side Comparison

To get a more in-depth look at the Flutter vs. Kotlin 2022 comparison, below is a side-by-side look at where each platform stands in terms of the following criteria: Performance, Community, and Learning Curve.

PERFORMANCE Dart is the programming language used by Flutter. Because Flutter apps are built directly to machine code, they are extremely quick. 

As a result, Flutter has a higher performance rate – it aspires for 60 frames per second (fps). Flutter’s performance is typically judged by how well an app’s user interface appears or functions. This option is because Flutter is a user interface toolkit that focuses on the application’s front end.

Kotlin is a programming language that you may use for a variety of tasks. 

In terms of performance, Kotlin apps are faster and run well across all platforms. Google alone has 60 Kotlin-based apps. Kotlin code gets compiled in the same format as the platform’s written form. As a result, Kotlin is one of the most powerful and advanced platforms for creating cross-platform applications.

COMMUNITY Google-based Flutter gets supported by a large open-source community of programmers, designers, and tech enthusiasts. Flutter’s user base continues to increase, and it gets employed by well-known organizations worldwide. The Flutter community always makes Flutter a top choice for creating fast and elegant web, mobile, and desktop user experiences. In this comparison to Flutter, Kotlin is a step forward. Flutter is a new framework, while Kotlin is a mature and reliable language that is now one of the approved languages for developing Android apps. Kotlin is a dynamic language with a vibrant ecosystem and a rapidly expanding worldwide community. JetBrains, a major software development business that creates tools for developers and project managers is behind Kotlin.
LEARNING CURVE Dart is used by Flutter. Dart is a programming language that you may be used to create web, mobile, server, and desktop apps. It got created by Google and is simple to learn if you are familiar with programming languages such as ++, C#, Python, JavaScript, and others. Dart is a type-safe programming language that is comparable to JavaScript. It is simple to learn and utilize for developers. The syntax of Kotlin is concise and similar to that of other programming languages like Scala, Java, Groovy, and Swift. It is much easier for Kotlin developers who come from a Java background to move to Kotlin. Kotlin is a fully Java-compatible language, making it simple for developers to use in new and existing applications.


You have now seen how Flutter and Kotlin 2022 differ from a variety of angles. It may be time to make the decision.

Flutter vs. Kotlin 2022: The Winner

Although anticlimactic, there is no clear winner when it comes to Kotlin vs. Flutter; you will have to choose based on your specific situation, team, and possibly current codebase. Moreover, Google supports both Kotlin and Flutter, so you cannot go wrong with any.

Flutter is an excellent low-cost option for startups with a small team because it allows them to create many apps with a single codebase, needing less effort and fewer developers. For those dealing with any pre-existing Java code, Kotlin is a terrific choice, but keep in mind that experienced engineers will be tougher to come by.
