Comparison of Kotlin vs Flutter

Comparison of Kotlin vs Flutter

Perhaps you’ve heard of the Kotlin programming language and the Flutter framework. They have recently experienced tremendous growth in popularity.

Since May 2021, when Google began to formally give support to Kotlin in the area of developing mobile applications, it has experienced tremendous growth among developers.

Your ability to recognize the Comparison of Kotlin vs Flutter is crucial. Learn to develop mobile apps effectively through our Android Training in Chennai with IBM Certification at Softlogic Systems.

What is Kotlin?

An all-purpose programming language called Kotlin was created with cross-platform compatibility in mind. Despite being built on the Java class library’s (JCL) operation, it has a precise syntax that is not only very understandable but also quite compact.

When Kotlin‘s scope is discussed, it may be said that it is very broad. Kotlin is used for everything, including the internal tooling system used by Uber and the Gradle plugins. To give users a better user experience, many social media firms have switched from Java to Kotlin.

Kotlin is used often by several businesses, like Autodesk, VMware, Yandex, Chalk, etc, for their needs.

The qualities listed below give Kotlin the advantage when selecting a programming language for application development:

Application Porting : Kotlin can still function well with all of an application’s Java-developed components. If expanding the functionality of an existing application is necessary, Kotlin is more than capable of handling all of the tasks involved without the need to change the development environment or even overhaul the native app’s entire architecture.

High Readability : Kotlin‘s syntax is quite simple and of a very high level. This not only makes it more readable but also simpler for developers at all skill levels to work with. Kotlin‘s straightforward syntax can make it easier to develop large amounts of code for an application if that is necessary.

Debuggability : Kotlin comes with a built-in compiler that can quickly and automatically look for flaws. This further guarantees that defects won’t impede the application’s progress. Kotlin is superior to Java in this aspect because it can quickly notify crashes and fix them.

What is Flutter?

Google created the well-known framework Flutter in-house. Its architecture supports a wide range of components, and it is programmed using the Dart programming language.

The following entities are included in Flutter’s architecture, to put it simply:

  • Dart Development Platform
  • Flutter Engine
  • Custom Widgets
  • Fundamental Libraries

As its applications are compatible with both Android and iOS, Flutter has become extremely popular.

The end-to-end application development approach may be utilized with Flutter to build a variety of applications because it is incredibly powerful and delivers an exclusive bundle.

Flutter’s widespread adoption by major corporations like Google, Tencent, eBay, Groupon, The New York Times, and other well-known names shouldn’t come as a surprise.

The following are a few benefits of utilizing Flutter:

Hot Reload : It is a feature that is particularly popular in Flutter that allows developers to see changes as they are made to the code in real time.

As a result, they can immediately comprehend the application and inherently make modifications. Flutter should be used if creating an application that needs lots of updates is necessary.

Minimum Viable Product (MVP) Development : Flutter gives developers several tools and strategies to accomplish a lot without having to invest a lot of time in development if there is a need to quickly lay a foundation and construct an application with time being the main constraint.

Flutter is acknowledged to have an advantage in situations where quick prototype development is involved.

Quick Start : Even on moderately spaced hardware, Flutter is quite simple to set up and start. It can function properly without any form of cutting-edge technology. Flutter has a lot more to offer because it is still a relatively new framework.

Kotlin vs Flutter

Kotlin vs Flutter
User ExperienceKotlin supports the use of local libraries to quickly and elegantly design apps.Being an SDK, it offers many internal tools to create a beautiful and complete UI with little effort.
PerformanceIt is designed to be close in terms of simply describing identical configurations required to meet the purpose.Flutter supports “hot reload,” which enables quick changes in the backend to be promptly reflected in the frontend.
PopularityKotlin is undoubtedly well-liked by developers, as seen by its 33,000 ratings and 4,000 clients on GitHub.Flutter is one of the fastest-growing app development platforms with 13,000 customers and over 91,000 stars.
Support for TestingThe globe over, it is renowned for its effective use in unit testing Android applications.When used with Firebase, it offers a wide range of tools and functionalities as well as helpful documentation.
IntegrationKotlin offers multi-platform to assist users in working in their local structures using their libraries and tools.Flutter offers programmers quick and efficient methods for both iOS and Android development.
Platform SupportIt may be used to create use cases for wristwatch OS, Android Auto, iOS, tvOS, and other operating systems.Although cross-platform, it does not intend to provide support for tvOS, Android Auto, or CarOS.
Programming LanguagesJVM, JavaScript, and native programming languages are supported to make it simple for developers to write code.Its functionality offers improved compatibility and a wide range of testing tools because it was built around Dart.
Ease of LearningKotlin is easy for newbies to get started with and learn quickly because it is a statically-typed language.Flutter offers a solid foundation for Android and iOS development and makes use of the programming language Dart.


Which language—”Kotlin or Flutter—is the best tool? The solution, however, is not as obvious as it first appears. Kotlin is quickly overtaking other programming languages as industry leaders like Google shift their whole development strategies to Kotlin.

Flutter, on the other hand, is thriving in the market since Google invented it and has many ambitions for the future.

Whether comparing Kotlin vs Flutter’s performance, both of them excel at what they do.  As has been seen numerous times in the past, if huge companies like Google are showing a lot of interest, then it is safe to believe that Kotlin and Flutter have a promising future.
