Flutter vs. Kotlin Multiplatform: Which one can help you succeed?

Sagar Bagsariya,

How to choose the right cross-platform app development framework between Flutter vs. Kotlin? In one line, you need to evaluate complexity, platform support, native integration, long-term maintenance, and more factors.

But if you ask which framework has an edge over the other between Flutter or Kotlin multiplatform, it’s Flutter. It’s not what we are saying but Statista.

A survey in 2022 on the most used cross-platform app development frameworks reveals that 46% of developers use Flutter compared to 3% of Kotlin Multiplatform users.

However, that doesn’t mean nobody uses Kotlin Multiplatform. Your job as a CEO/CTO might be to opt for the right cross-platform development framework that meets your app requirements. And to address that, you will need to study both frameworks as well as compare Flutter vs. Kotlin Multiplatform head-on. 

Flutter vs. React Native has been a famous tug-of-war in the cross-platform world, just in case you are interested.

As for this blog, we are focusing on Flutter vs. Kotlin Multiplatform to clear your confusion between these two. We will consider factors such as performance, scalability, ease of use, and more in a head-on-head comparison. 

But first, let’s understand both frameworks’ fundamentals.

What is Kotlin?

Kotlin is a general-purpose programming language developed by JetBrains in 2016. It allows developers to share code, data, and business logic across multiple platforms, such as iOS, Android, and the web. This makes it a versatile language that can be used in various environments. It is also known as Kotlin Multiplatform because of its ability to work on different platforms.

Many developers prefer Kotlin over other programming languages because of its simplicity and ease of use. It is designed to reduce the risk of programming errors and crashes, making it a reliable choice for developers. 

Additionally, it is an SDK(Software Development Kit) rather than a framework, which means that it can be gradually integrated into existing applications.

Pros of Kotlin Multiplatform

  • Modular integration with existing apps.
  • Easy to learn with familiar syntax (Swift and Java).
  • Single codebase for business logic sharing.
  • Utilizes native UI elements for an authentic experience.

Cons of Kotlin Multiplatform

  • Still in beta that may raise concerns for some companies.
  • Limited community support and libraries.
  • Requires familiarity with different tech stacks, not just Kotlin.
  • Takes more development resources compared to Flutter.

What is Flutter?

Flutter has become increasingly popular because of its ability to create high-performing, visually attractive apps with a native-like feel. Moreover, it uses Dart programming language with ahead-of-time compilation that enables fast and efficient app development.

One of the major benefits of using Flutter for enterprise apps is its ability to share a single codebase across multiple platforms, including Android, iOS, Mac, Windows, and Linux. Therefore, it is a cost-effective solution for developing apps for multiple platforms.

Above all, Flutter’s widget library, which is built on the concept of reactive programming, allows for the creation of highly responsive and customizable UI. It also has an active and supportive community, which contributes to its growing popularity.

The framework has been adopted by many companies and developers for creating apps in various industries, for example, eCommerce, entertainment, social media, and utility. With its continued growth and development, Flutter is poised to become one of the leading frameworks for mobile app development in the future.

  • Attractive app design with custom widgets.
  • Strong community support and popularity.

Cons of Flutter 

  • Dart language learning curve for developers.
  • Some limitations in available libraries compared to native development.

You are now acquainted with both frameworks. So, let’s dive into an analytical comparison of Flutter vs. Kotlin.

Flutter vs. Kotlin: how much does it cost to hire app developers? 

The cost to hire Flutter app developers and Kotlin developers differs based on location, expertise, and industry. For example, hiring Flutter or Kotlin developers with domain expertise, say for healthcare, from the USA will be costlier than hiring from India. 

However, businesses prefer Kotlin and Flutter app outsourcing to save costs for more important aspects. The outsourcing approach allows enterprises to extend their existing team or hire a dedicated team from an offshore software agency with affordable rates. Consequently, companies save on office infrastructure, employee engagement, and perks while accessing global expertise for their projects.  

Let us get a basic idea of how Kotlin and Flutter Developers’ hourly rates vary based on their location.
