Kotlin Vs Flutter: What to Choose?

Kotlin Vs Flutter: Know the Basic Concept

The mobile app market will be growing. But how to succeed in this thriving market?

Well, both Kotlin and Flutter are powerful in their own way. But who is the best?

Kotlin is a programming language majorly supporting Android development, offering compatibility with Java. On the other hand, Flutter is a cross-platform framework utilizing Dart as a programming language and providing compatibility for both iOS and Android.

To make the best choice, let’s take a deeper look!

What is Kotlin?

Officially, Kotlin is a general-purpose programming language created by the JetBrains in 2011 to replace Java. However, its original release was formally introduced in 2016. The final version of Kotlin is 40% more compact than Java’s predecessor which makes the app development process faster.

Further, Kotlin ran on Java’s virtual machine which simply means Kotlin can be used where developers used Java – whether it be the backend, the web, the desktop app, or more.

So is it true to say that Kotlin is a language for all platforms?

Well, some of the tech giants have already put their trust in Kotlin like Uber, Amazon, Netflix, and more. So Kotlin’s credibility and scalability are fair enough to be trusted!

Advantages and Challenges of Kotlin

Kotlin is a statistically typed programming language used by over 60% of developers but still there are reasons that 40% are not using it. So before you hire mobile app developer in India, let’s weight the pros and cons of Kotlin.

Advantages

Kotlin is an SDK and not a framework; therefore, it is unnecessary to move the complete app to the platform. One can start working even with a single characteristic.
Kotlin bears a resemblance to Scala and Swift, making it easy to learn and design a cross-platform app using a multi-frame.
UI creation is not restricted in Kotlin; one can work on any aspect of the app without limitations.

Challenges

There are fewer libraries in hand right now as Kotlin is still a fledgling. Once Date TimeLibrary comes situation will improve, App developers need to understand each platform and API to manage Kotlin better.

What is Flutter?

Introduced in 2017, Google’s Flutter offers developers a unique set of UI development toolkits for rapid app development. It empowers efficient creation across multiple platforms. Despite being young, Flutter is already trusted by 49% of developers.

It is an open-source framework developed and supported by Google. It uses Dart programming language and based on single-code-based principles and offers a wide range of features to overall enhance the app development experience.

But since it’s new, so how far it will stay in the future?

Firstly, it is a Google initiative and secondly, Flutter is already trusted by leading apps including Google Ads, Alibaba, Instagram, and more. So it is fair enough to say that it won’t be going anywhere.

Advantages and Challenges of Flutter

Flutter is already appreciated by developers but still it is at growing stage. Therefore, Flutter also has some strengths and weaknesses.

Advantages

Operating cost and development costs are considerably lower because of native-like apps with single-based code.
With numerous widgets, Flutter can produce customized facilities for its users.
As Flutter assists in developing apps for both Android and iOS in a minimum period, it thus fits for MVP development.

Challenges

The language employed, Dart is still unfamiliar to all the app developers, and this is quite a barrier.
The framework size is vast; therefore, the apps are much more prominent in dimensions, which is detrimental in app development today.

Selecting the right platform always depends on the type of project and its fundamental requirements. Look for the right set of qualities that these platforms possess and match them with your requirements; you will have the perfect combination. So before you hire a top software development company in India, let’s get into a detailed comparison.

Kotlin Vs Flutter: A Detailed Comparison

There is no doubt that Kotlin and Flutter are young and have quickly become developer’s choice. But both have different purpose and specific for different businesses. So before you get incline for any particular technology, let’s get the battle started between Kotlin Vs Flutter.

1. Kotlin Vs Flutter: Github Stars For Popularity Evaluation

Flutter Github Rating : 160K Stars | 26.2K Fork

Kotlin Github Rating: 47k Stars | 5.6 k Fork

Considering the rating on Github rating, Flutter is clearing having a upper hand over Kotlin. However when it comes to the usage, 60% of developers prefer using Kotlin whereas 45% of developers prefer staying with Flutter.

So make a choice based on popularity won’t make a logical decision. So let’s further evaluate the other parameters as well.

2. Kotlin Vs Flutter: Performance

For any mobile app, performance is an important element. Flutter offers excellent rendering capabilities as it directly builds on machine code.

Kotlin: Known for its performance on the JVM, Kotlin compiles to bytecode, offering efficiency. Its close integration with Java allows developers to leverage Java’s performance optimizations.

Flutter: Flutter’s performance is commendable. All thanks to its compilation of native machine code. This allows for more responsive user experience, especially in graphics-intensive applications.

Winner: Flutter – for its compilation to native code, potentially offering better performance.

3. Kotlin Vs Flutter: Documentation and Learning Curve

Dart is used by 2986 developers in comparison to Java which is used by 17.1 million developers. It means, Java is more easier and familiar language than Dart. Therefore, any developer familiar with Java can use Kotlin.

Kotlin: Kotlin is considered as easy to learn, especially for those already familiar with Java. It has clear syntax and offers comprehensive documentation and a mature ecosystem for app development.

Flutter: Flutter’s documentation is robust and beginner-friendly. Its widget-based architecture simplifies UI development. The hot reload feature enhances the learning curve, enabling quick feedback.

Winner: Tie – Both Kotlin and Flutter provide excellent documentation and have relatively manageable learning curves.

4. Kotlin Vs Flutter: Platform Versatility

Flutter surpasses Kotlin in evaluating app compatibility across multiple platforms.

Kotlin: It is primarily recognized for Android development, But it is also supported by Java’s Virtual Machine, Kotlin which makes it versatile and can be used for backend, web, and other applications.

Flutter: Flutter excels in platform versatility, offering a single codebase for both iOS and Android. Its ability to extend to web and desktop development widens its application scope.
