Flutter vs. React Native vs. Kotlin: Which is the Best Choice for Your Mobile App?

As we all know, cell phones have become a fundamental and essential piece of human life today. Many individuals around us use cell phones; it's become our necessary evil. This insane drive for cell phones has caused the versatile mobile application development market to increase to a great extent. Numerous application engineers wish to fabricate various cell phone apps, whether Android or iOS. And some of these need to take care of Android and iOS markets.

With regards to creating and developing applications on Android or iOS platforms, numerous native and cross-platform software development kits (SDKs) are accessible, like Flutter, React, and Kotlin. Be that as it may, with countless such choices in the rundown, it becomes hard to pick the suitable mobile development kit. Going with the best decision lies in the hand of an app developer.

However, if you are facing issues while picking one among Flutter, React Native, and Kotlin here's a detailed comparison that can help you settle on the best decision. In this blog, we will discuss the main features of these different SDKs so that you get a brief idea of how they help us build an application.

Some of the main attributes that are to be get considered while selecting the ideal platform for mobile app development are as follows:

  • User Interface

  • The Language Stack

  • Performance

  • Pricing

  • Minimum Supported Platforms

  • Market & Community

Flutter vs React Native vs Kotlin

Now, let us discuss the difference between top SDKs per the above attributes.

User Interface

Each application gets decided by its UI within a few moments. Thus, the GUI of an application ought to be simple as well as engaging, comparing these attributes among the SDKs we have:

Flutter: Flutter also provides one of the best User Interfaces. It's a Google UI toolkit that builds beautiful, natively compiled web, mobile, and desktop apps from a single codebase.

React Native: React Native associates with native UI controllers, which gives a native user experience with a marvelous & astonishing graphical user interface. It utilizes the ReactJS library's immeasurable UI elements and UI development.

Kotlin: Kotlin has likewise been one of the languages that assist users/clients with creating cross-stage applications and is upheld by Google for mobile applications on Android. It permits users to construct native applications and is perfect in features and user experience since it is 100% interoperable in Java. It tends to be joined with SDKs to foster compelling user encounters.

The Language Stack

Each SDK utilizes different programming languages to construct an application and offers developers remarkable advantages.

Flutter: Flutter involves Dart as a programming language to improve top-notch, versatile mobile applications for Android, iOS, and Windows. Dart is based on Java and C/C++.

React Native: It utilizes the most famous and dynamic web improvement, undeniable level programming language JavaScript and React. JS. It likewise permits composing some elements in Swift, Java, or Objective-C, making React Native the best mobile development framework among all the other programming languages.

Kotlin: It is a statically composed, broadly helpful programming language. It gets intended to interoperate completely with Java. It's like Java and targets JVM (Java Virtual Machine), JavaScript, and Native.

Performance & execution is the most significant characteristic when developing cross-platform mobile applications. Each application made on a different platform has another performance.

Flutter: Flutter deals with the language Dart, which removes the credits when looking at the performance attributes. Involving Dart as a language eliminates the JavaScript connecting for beginning interaction with local components. The speed of the applications offered by Flutter is remarkable.

React Native: The performance of React Native applications is the same as that of native apps, as it gives the code components explicitly to native APIs. It is exceptionally centered around providing the best performance.

Kotlin: Kotlin: Kotlin is a superior option in contrast to Java, and its bytecode is practically like that of Java. It targets JVM, yet in addition, it assembles JavaScript/native code. It performs quicker than Java and is better-concerning security, syntax structure, and compatibility.

The price of using these platforms is acceptable as all of them are open-source platforms.

Flutter: Flutter is an open-source platform and is free of cost.

React Native: It is also an open-source platform, and developers can utilize the libraries and their tools free of cost!

Kotlin: Kotlin is also free of cost, and its source code is available on GitHub.

Minimum Supported Platforms

Before building an application on a specific platform, you must understand what platforms are upheld by the SDKs you use for your app development.

Flutter: It supports iOS 8+ and Android Jelly Bean, v16, above 4.1.x versions.

React Native: It supports iOS 8+ and Android 4.0.3+ versions.

Kotlin: Apps built on Kotlin can run on any older versions of Android with no issues and iOS 8+ versions.

Community & Marketplace

Having an extraordinary community and market helps your application development and allows you to comprehend the best & well-known platform.

Flutter: As Flutter is still a new platform and in the progress stage, it has a small community and market compared to other popular platforms. But as Google creates it, it shows that they want to make it a big thing in the mobile industry. However, working with Flutter is easy, and using it is fun.

React Native: It has the most incredible community & marketplace, and the organization network of its developers is still in the developing phase. It makes it simple for the developers to begin with the React Native projects. It is known for giving simple native applications using the ReactJS library and the most fundamental web development language, JavaScript. It makes the platform more substantial and more famous.

Kotlin: It's seen that Google itself is becoming Kotlin-oriented, and many developers are moving towards it. Likewise, a considerable lot of Java applications are being rewritten in Kotlin, and with its quick and smooth features, its market has been developing. Kotlin is seen as the future of building Android applications.

Wrapping Up

For the advanced development of native and cross-platform applications, every one of the above three platforms is known to be dependable. They all target diminishing the time and costs for application development and improving application execution. Every stage is best in its specific manner, and the most common way of pursuing a decision among everyone is to rely on the necessities and needs of the project.
