Kotlin vs Flutter

If someone is planning to invest in mobile application development, the pressing question one may have is, which is the best framework for developing a high-performing application? This blog provides a quick comparison between Kotlin vs Flutter.

Before starting with Kotlin vs Flutter comparison, let’s begin with discussing them one by one:

Kotlin vs Flutter comparison

Flutter vs Kotlin Performance

Flutter: One of the most significant benefits of using Flutter is that it presents organizations with hot reloading functionality. The functionality leads to makes it simple for the users to execute any modifications at the backend and view the difference at the front-end simultaneously. In this manner, it becomes easy to decide if the looks are perfect for the elements of applications.

Kotlin: One great advantage of using Kotlin for cross-platform development is that the multiplatform organizes the code to the explicit with the same format as the targeted platform. This makes it a stable platform for superior performance in its native counterparts.

UI Experience

Flutter: Flutter is regarded as the tool for cross-platform developments. Hence, developers look for a variety of widgets available on the platform to customize the app interface. With Flutter, developers can get a chance to use various widgets for app development, making the app development process far more comfortable and quicker. Flutter comes with an advanced SDK to customize the app that fits your business needs.

Kotlin: Its multiplatform gives the UI developers freedom to craft a unique and highly effective mobility solution without the need to follow any constraints or set-in-stone instructions. Developers can build an app that perfectly fits your vision.


Flutter: Flutter provides the user with the functionality of building the app with both Android and iOS, with fewer costs, time, and efforts. This feature empowers Flutter to make a perfect option for MVP development and create a prototype that is used for testing.

Kotlin: The Kotlin framework provides the user with a multiplatform function and acts within the native ecosystem rather than constructing one. Therefore, all the app experts can operate with the same tools and libraries they have been utilizing during the native development, involving Jetpack Compose and SwiftUI.

This means that they require third-party libraries and the tools to bridge a combination with the native environment. However, it involves a Flutter cross-platform SDK, which is presented basically as a UI development tool.

Pros and cons of Kotlin


  • 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.


  • 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.

Pros and Cons of Flutter


  • 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.


  • 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 requirement; you will have the perfect combination.
