Difference Between Flutter and Kotlin

Flutter


Flutter is a free and open-source mobile UI framework created by Google and released in May 2017. In a few words, it allows you to create a native mobile application with only one codebase. This means that you can use one programming language and one codebase to create two different apps (for iOS and Android).

Flutter consists of two important parts:

  • An SDK (Software Development Kit): A collection of tools that are going to help you develop your applications. This includes tools to compile your code into native machine code (code for iOS and Android).

  • A Framework (UI Library based on widgets): A collection of reusable UI elements (buttons, text inputs, sliders, and so on) that you can personalize for your own needs.


Features

The following are the essential features of Flutter:

  1. Open-Source: Flutter is an open-source framework for building desktop and mobile apps.

  2. Cross-platform development: It allows the developer to write the code once and can run on different platforms. It saves the time, effort, and money of the developers.

  3. Hot Reload: If we modified the Flutter code, the changes could be seen instantaneously with Hot Reload. Due to this feature, the developer can be able to fix the bugs instantly.

  4. Widgets: The widgets are used for developing customizable specific designs. Flutter has two sets of widgets: Material Design and Cupertino widgets that help to provide a glitch-free experience on all platforms.

  5. Accessible Native Features: This feature allows us to easily access the Flutter's native code, third-party integration, and platform APIs for app development.

  6. Minimal code: Flutter uses the Dart programming


with the JIT and AOT compilation method to improve the overall start-up time, functioning, and the performance of an app. JIT refreshes the UI without putting extra effort.



Kotlin

Kotlin is a general purpose, free, open source, statically typed “pragmatic” programming language initially designed for the JVM (Java Virtual Machine) and Android that combines object-oriented and functional programming features. It is focused on interoperability, safety, clarity, and tooling support. Versions of Kotlin targeting JavaScript ES5.1 and native code (using LLVM) for a number of processors are in production as well.


Features

Following are the features of Kotlin Language:

  1. Concise: Kotlin language allows developers to reduce the writing of the extra codes that makes Kotlin more concise.

  2. Null safety: Kotlin is the null safety language. The main aim of this feature is to eliminate the NullPointerException from the code.Interoperable.

  3. Interoperable: This feature allows the developer to easily calls the Java code as well as Java can also use the Kotlin code.

  4. Smart cast: It explicitly typecasts the immutable values and inserts the value in its safe cast automatically.

  5. Tool-friendly: We can build the Kotlin programs using the command line as well as any Java IDE.

  6. Extension function: Kotlin supports extension functions and extension properties that help to extend the functionality of classes without touching their code.


Difference Between Flutter and Kotlin


Flutter Kotlin

It is a framework that was first introduced by Google.

It is a programing language that was first introduced by JetBrains.

It was Released in 2017

It was Released in 2010

It uses Dart programming to build mobile apps.

It is itself a programing language that uses Java, JVM, JavaScript, and Native for creating applications.

In Flutter, developers must have to learn Dart programming to build an app.

It has an easy learning curve because it is very similar to Java.

It has well organized and more informative documentation where we can get everything that we want in one place.

It also provides well-structured documentation to the developers. Since it is in the development phase, its libraries can be changed at any time.

It has a wide variety of testing features along with a unique widget testing feature.

Its main focus is to deliver backend development services and uses Firebase as a secure backend option.

It can deploy on Mobile, Desktop, and Web.

It can deploy on Mobile, Desktop, and Web.

Since Flutter is a UI tool, so it needs third-party libraries and tools to bridge a connection with the native environment.

It does not require third-party libraries and tools to bridge a connection with the native environment.

It has very good performance because of its Dart Programming. and there is no need to use JavaScript Bridge for starting interactions with the app

It has slow performance because JavaScript Usage and 100% interoperable in Java that decrease the speed of the applcation
