Flutter vs Kotlin: Who Will Rule the Cross-platform App Market?

Flutter vs Kotlin

Table of Contents

There was a time when building an app with React Native, and Flutter was considered cross-platform development. These two frameworks were relied upon by business enthusiasts and mobile app development organizations to establish a cost-effective presence on both Android and iOS.

Difference between Flutter vs Kotlin is that Flutter is an open-source, cross-platform SDK. It provides easy integration of third-party UI development tools. Kotlin is a programming language that is capable of developing native-like cross-platform apps. For this, it makes use of native tools like SwiftUI and Jetpack Compose.

However, now that Kotlin has matured and entered the battle, everyone is wondering who the ultimate cross-platform application industry dictator will be. We’ll go through the in-depth Kotlin vs. Flutter comparison in this blog to help you choose the ideal option for your cross-platform programming and development needs. While we’ll explore Kotlin’s cross-platform capabilities here, this blog will teach you how to use Swift to create Android apps.

But first, let’s get acquainted with both.

What is Kotlin Multiplatform, and how does it work?

Kotlin multiplatform is a feature of the language that allows it to be used for more than just Android app development. It allows developers to share code, data, and business logic across a variety of platforms, including iOS, Web, Linux, macOS, Android, and the Java Virtual Machine (JVM).

Although the idea of investing in Kotlin app development for cross-platform is still new to the industry, it has been embraced by a number of well-known companies.

What is the Flutter User Interface Framework?

Flutter vs Kotlin

Flutter is an open-source SDK that allows you to create attractive, native-looking mobile, web, and desktop apps using a single codebase. It was first released in 2015 with the goal of preparing a market for Google Fuchsia.

Google Flutter addressed a number of current technological &  market issues and offered effective answers. As a result, Flutter quickly rose to prominence as an ideal cross-platform app development framework. Not only that but it was included in the list of technologies with which big brands collaborate.

Now that we’ve covered both, let’s evaluate which is better for cross-platform mobile development: Kotlin or Flutter.

1. Popularity on the market

Both Kotlin and Flutter are open-source, free-to-use programming languages. As a result, developers are showing interest in collaborating with both.

When compared to Kotlin, Flutter’s popularity is skyrocketing, according to Google Trends. Similarly, Kotlin has 28.3K stars and 3.29K forks on GitHub, whereas Flutter has 69.5K ratings and 8.11 forks.

In comparison to Kotlin, this suggests that Flutter is gaining a lot of traction in the market.

2. Curve of Learning

When the learning curve is considered in the Flutter vs. Kotlin native duel, the latter unquestionably wins. One reason for this is that it is compatible with Java, and Google has offered different Kotlin learning courses.

When it comes to Kotlin and Flutter, though, the situation is a little different. In comparison to Flutter, the Kotlin Multiplatform ecosystem is fresh and has few resources available on the market.

As a result, Flutter takes first place in the competition.

3. Performance

Flutter lets developers use the same language for both layout and backend needs while also benefiting from quicker animation speed.

However, it is still a long way behind Kotlin in terms of market share. The main reason for this is because Kotlin code compiles in the same format as the platform in question.

So, if you’re wondering whether Kotlin or Flutter is superior, the answer is both. The latter is the winner of this flutter vs. Kotlin battle.

4. Third-Party Libraries and Tools Integration

Rather than creating its own platform ecosystem, Kotlin multiplatform works inside existing ones. As a result, app developers can use the same tools and frameworks they used for native development, such as Jetpack Compose and SwiftUI. As a result, they won’t need to rely on third-party libraries and tools to connect to the native environment.

It is, nevertheless, essential in the case of the Flutter cross-platform SDK, as it is primarily a user interface development tool.

5. Backend Development Scope

When it comes to understanding the differences between Kotlin and Flutter for backend software development, the former has an advantage over the latter.

While Flutter uses Firebase, a powerful BaaS (Backend-as-a-Service) platform, to ensure excellent backend capabilities, Kotlin multiplatform allows developers to create backend code.

6. Focus on a variety of platforms

Flutter use cases currently include mobile (Android and iOS) and online applications. It can’t be used to make an appearance on tvOS, Android Auto, CarOS, or WatchOS.

In the case of the Kotlin multiplatform, however, there is no such restriction. It can also be used to create apps for devices and platforms other than mobile.

As a result, using Kotlin multiplatform for mobile app development services firms is a fantastic choice for launching their app idea on every imaginable platform and device.

7. Job and Salary Expectations

When comparing Kotlin multiplatform versus Flutter language, another significant element to consider is employment and income scope.

According to the StackShare community, 268 organizations and 210 developers have listed Kotlin as a technology stack, whereas 42 companies and 146 developers have listed Flutter cross-platform as a technology stack.

Now, because Kotlin multiplatform isn’t a stand-alone platform, it’s an experimental extension of the native language that may be used within the Kotlin environment, giving the idea that it offers more job opportunities.

8. Community Support and Documentation

In comparison to Flutter, the Kotlin multiplatform is still in its early stages and is currently in development. As a result, the documentation and community support for the latter lag behind that of the former. However, once the multiplatform is established, it is envisaged that documentation and community strength will improve, further encouraging everyone to use Kotlin for cross-platform development.

We’ve now seen how Flutter and Kotlin vary from a variety of angles. To make the decision easier, it is necessary to understand the benefits and drawbacks of each option.
