Flutter vs Kotlin – Which Is Best for Cross-platform App Development?

flutter vs kotlin

Hi Readers!

Gone are the days when there was just one way to build cross-platform mobile apps: React Native. Businesses are always looking for new ways to attract more users to their mobile apps.

Here, In this post, I will go over the differences between Flutter and Kotlin, as well as the comprehensive comparison guide of two leading cross-platform development frameworks.

Are you interested?   🙂 Definitely, i am sure about it

Let’s get started with a detailed comparison of these two technologies :- Flutter vs Kotlin.

Detailed Comparison Based On Numerous Parameters :- Flutter vs Kotlin

Let’s first start with the Flutter vs Kotlin- Overview

Flutter: As you know, Flutter is a user interface toolkit developed by Google for creating natively built, appealing, feature-rich web, mobile, and desktop programs. One of the fastest-growing open-source communities is Flutter. 

Developers may develop apps for iOS, Android, Linux, Mac, Windows, Google Fuchsia, and the web from a single codebase.

Kotlin: A general-purpose programming language. It’s made to work hand-in-hand with Java and is Google’s preferred programming language for Android app development. After Google announced first-class support for Kotlin on Android, it immediately gained popularity.

Flutter vs Kotlin Market Popularity

In terms of popularity, both Flutter and Kotlin frameworks are highly popular mobile app development wise. Since both these frameworks are open source and free to use, mobile app developers are showing interest in working with them. There are enough reasons to justify why Flutter shines for creating cross-platform solutions, however, Kotlin has its own features and functions that make it shine as a top mobile app development tool.

If you look at Google Trends, you will see that Kotlin is skyrocketing in terms of popularity as compared to Flutter.

Flutter vs Kotlin Market Popularity

You can also compare Flutter and Kotlin based on market popularity, apart from the above. Both are free and open-source tools, but Flutter is more popular than Kotlin.

Flutter vs Kotlin Performance Comparison

As we all know, performance matters a lot!

Dart is the programming language used by Flutter. Flutter apps are built directly to machine code; they are speedy. It does not rely on the web view or the device’s OEM widgets; instead, it renders each view component using its rendering engine. All essential platform differences, such as icon and fonts, navigation, scrolling, and other UI-related parts, are included in its extensive widget collection. This will aid in achieving native-like performance on both Android and iOS devices.

On the other hand, Kotlin is a programming language used for anything. As a result, it is frequently similar to Java. This object-oriented programming language is commonly used for Android and cross-platform app development.

Flutter and Kotlin are excellent, and it is mainly dependent on the functions and features involved in app development.

Flutter vs Kotlin UI Experience Comparison

When it comes to cross-platform apps, the user interface is crucial. One of the critical goals of cross-platform development is to create a native-like experience. Flutter works similarly. It provides a consistent user experience across all platforms. Flutter is a user interface toolkit that handles all UI aspects to give a native performance on iOS and Android with a single codebase.

Whereas, the Kotlin programming language provides an accessible environment for building app user interfaces. This implies there are no limitations on designing the user interface for your app. It allows you to use native functionality or write platform-specific code as needed.

Flutter vs Kotlin Language Comparison

The syntax of Flutter’s programming language, i.e., Dart, is easy to learn and understand as it supports object-oriented elements. On the other hand, Kotlin requires a developer to know Java and other languages.

  • Learning Curve

Flutter uses Dart. Dart is a programming language used to create web, mobile, server, and desktop apps. It was created by Google and is simple to learn if you are familiar with programming languages such as C++, C#, Python, JavaScript, etc.

The syntax of Kotlin is concise and similar to that of other programming languages like Scala, Java, Groovy, and Swift. As a result, it is much easier for Kotlin developers 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.

  • Scope in the development

When it comes to comparing the scope of Kotlin with Flutter in backend development, it is clear that the former is one step ahead of the latter.

  • Integration of third-party tools

Flutter needs to use third-party tools and libraries as a UI development tool. Whereas, Kotlin multiplatform comes up with various built-in tools and third-party libraries, which means you don’t need to look anywhere else for the same. 

Flutter vs Kotlin – Which Is Best for You?

Nowadays, when it comes to Flutter vs Kotlin, Flutter usually takes the lead simply because it is more well-known and has a larger support community. Kotlin, on the other hand, is only a matter of time before it becomes the next big thing. Both Google’s Kotlin and Flutter frameworks are dependable, aiming to cut development time and cost to establish a presence on Android and iOS platforms.

Flutter is more popular than Kotlin, a relatively young language. Kotlin, on the other side, is the language of choice for creating Android apps. But on the other hand, both frameworks provide native-like performance with a single codebase. So if you still have questions about which option to choose, call a team of specialists who can assist you in making the best decision.
