Flutter Developer with Kotlin Salary in 2024

Median Salary Expectations:

How statistics are calculated

We count how many offers each candidate received and for what salary. For example, if a Flutter with Kotlin with a salary of $4,500 received 10 offers, then we would count him 10 times. If there were no offers, then he would not get into the statistics either.

The graph column is the total number of offers. This is not the number of vacancies, but an indicator of the level of demand. The more offers there are, the more companies try to hire such a specialist. 5k+ includes candidates with salaries >= $5,000 and < $5,500.

Median Salary Expectation – the weighted average of the market offer in the selected specialization, that is, the most frequent job offers for the selected specialization received by candidates. We do not count accepted or rejected offers.

Where is Kotlin used?

Android App-titude

  • Android's heart beats in Kotlin! Devs ride the green robot with less boilerplate code and niftier UI tricks.

Server-Side Shenanigans

  • Backend fun times! Kotlin plays nice with Spring, making servers do the cha-cha with smooth, scalable steps.

Multiplatform Mischief

  • Why pick sides? Write once, smirk at twice the coverage as Kotlin multiplatform targets both iOS and Android.

Desktop Tomfoolery

  • Not just for phones! Create cross-platform desktop apps that make Java swing dance in its boots.

Kotlin Alternatives




Java is a versatile and widely-used object-oriented programming language similar to Kotlin, especially for Android app development. It emphasizes portability, allowing code to run on any platform that supports Java without recompilation.

// Hello World in Java
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");

  • Platform-independent


  • Mature ecosystem with vast open-source libraries


  • Strongly-typed language enhances reliability and performance


  • Verbose syntax compared to Kotlin


  • Slower iteration speed for modern Android development


  • Does not support modern functional programming as well as Kotlin



Swift is an intuitive programming language for macOS, iOS, watchOS, and tvOS app development. It's designed to work with Apple's Cocoa and Cocoa Touch frameworks and provides interactive features for a seamless coding experience.

// Hello World in Swift
import Swift
print("Hello, World!")

  • Syntax is easy to read and write


  • Interoperability with Objective-C


  • Robust performance equivalent to Objective-C


  • Limited to Apple's ecosystem


  • Less mature compared to Java and Kotlin


  • Community and resources are growing but not as extensive as for Java



Scala is a high-level language that combines object-oriented and functional programming paradigms. Particularly suited for concurrent and distributed systems, it runs on the JVM like Kotlin and has strong static type system features.

// Hello World in Scala
object HelloWorld extends App {
println("Hello, World!")

  • Supports both OOP and functional programming


  • Highly expressive with concise syntax


  • Interoperable with Java


  • Steeper learning curve due to complex features


  • Less popular for mobile development


  • Compilation times can be slower


Quick Facts about Kotlin


Once Upon a Time in the Land of JetBrains...


Imagine a world where Java reigns supreme, sipping on its coffee cup, thinking it's the unchallenged ruler of the JVM kingdom. Then along comes Kotlin in 2011, strutting like a peacock, all decked out by the cool kids at JetBrains. Kotlin didn't come to start a fight; it came to be Java's buddy, intermingling with it smoothly, while secretly plotting to steal the show with its null safety antics and expressive code!

The Tale of Kotlin's Evolution


Flip the pages of Kotlin's diary, and you'll see its awkward teen years end when it hit version 1.0 in 2016, shouting "I'm ready for production - world, here I come!" Then it didn't just sit pretty; Kotlin did a glow-up for mobile app developers when Google gave it the nod in 2017, making it a favored language for Android. Cue the fireworks!

Sorcery of Inline Functions and Coroutines


Kotlin bewitched the development world with its inline functions, allowing you to pass functions around without holding up traffic in the runtime neighborhood. Then it cast a spell with coroutines, turning asynchronous programming from a frog into a prince. Behold the power of concurrency without the hair-pulling!


// Here's an inline function spell for you:
inline fun T.performMagic(action: (T) -> Unit): T {
return this

// And a coroutine enchantment:
suspend fun makeMagicHappen() {
coroutineScope {
launch {
