What is Kotlin and Flutter
Kotlin is a statically-typed programming language that was developed in 2010 by a team at JetBrains. Flutter is a cross-platform, development and rendering engine for mobile apps.
This article will explore the differences between Kotlin and Flutter, the benefits that each have to offer, and ultimately which language is better.
Kotlin was developed in 2010 by JetBrains as a statically-typed programming language for producing multi-platform applications. Kotlin primarily targets JVM and Android platforms. Although Kotlin is mainly written in Kotlin, you can still use it with Java and C++ projects if you use the cross-compiler.
Kotlin also supports an extensive set of libraries. While most of these libraries were created by JetBrains, other companies like Playtika have contributed libraries to support their platforms; in fact, Playtika has even created a Kotlin library called Ktor.
Flutter is a cross-platform engine that can generate native applications for Android and iOS platforms. Flutter was developed by Google, and it’s their response to the shortcomings of other cross-platform engines such as Xamarin.

How are they similar
Kotlin and flutter both operate on the JVM. They can also be used together to generate android applications. They both use reactive frameworks to program the UI. Interested? Let’s delve further.
Kotlin vs Flutter (differences and similarities)
Kotlin and flutter are two seamlessly integrated technologies that can be used to create android apps. Looking for a comparison? We’ve got you covered. This article will cover the similarities and differences between the two in order to help you decide which might suit your needs better.
Kotlin Introduction
Kotlin is a statically-typed general-purpose programming language with modern features. It was designed by JetBrains, the same people who created IntelliJ. Kotlin can be used for all sorts of development platforms, including android apps and server side applications written in JVM. Kotlin is open source and directly supported by Google in its Android Studio IDE and comprises of three modules:

How are they different
The syntax of Kotlin and flutter is similar. Kotlin is statically typed while Flutter doesn’t have type safety. Flutter uses Dart while Kotlin uses Java. Both can be used to program android applications, but flutter has a better UI performance than kotlin. If you have time to learn kotlin, you can also learn flutter. You can use flutter to write android apps, and when writing an app, you may find a developer in Appcelerator developing it for you.
The Objective-C language did not bring any new syntax. Instead, it was the way of using Objective-C that changed. This is the only difference between Kotlin and Flutter. The type system in kotlin is stricter than its equivalent in flutter. It has similar syntax with other languages such as JavaScript, Java(JS), Ruby etc.

Which one should you learn
Kotlin is a very good choice if you want to build applications that have an app store friendly appearance and appeal. In case you’re looking for a language with better performance on UI, choose flutter. In terms of similarity, flutter looks like Dart, while Kotlin looks like Java. But the way you write your code is a bit different. If you have the time to learn flutter, then go for it.
While learning android development, it can be difficult to decide which one you should learn. Both are equally powerful and flexible and their performance is on par with each other. While you can use the Kotlin programming language to build applications for Android devices, it is important to note that Google doesn’t support Kotlin. Therefore, if you want your application to thrive on the app stores, then use Kotlin because it reduces the time taken for a developer to write Android apps in comparison to java. On the other hand, if you want to build for iOS devices, then use the Swift programming language because the number of developers who can write swift is much larger than Kotlin.

Pros and cons of each language
Here’s the thing. Nowadays, developers see the future in Kotlin. We can also say that kotlin is a much better choice than java, as java has age-related problems (much more complex). But when it comes to UI performance and simple syntax, flutter is a better choice. So, if you have time, go for flutter. If not, choose kotlin.
For the pros and cons of each language, we will start from beginning. In this article, you will learn the kotlin pros and kotlin cons.
Basic syntax for kotlin language
To make things easier, you need to know basic syntax of kotlin. Basic syntax of kotlin is:
Class = camel case (classname) {
//Member variables and functions go here } 1 2 3 Class = camel case ( classname ) { //Member variables and functions go here }
The above code shows the basic syntax of kotlin. In the above code, Class is a class. You can have multiple classes in your kotlin application. Suppose we have three classes – UserApp, AwesomeApp and AmazingApp.
