Kotlin Support in React Native: Latest Version and Beyond
React Native, a popular JavaScript-based mobile app framework, has seen a surge in interest for Kotlin support. Kotlin, a modern statically-typed programming language, offers numerous benefits, including improved code safety, better interoperability, and enhanced tooling support. This article explores the latest Kotlin version for React Native, its features, and how to integrate it into your projects.
Why Kotlin for React Native?
Before diving into the latest Kotlin version, let's understand why developers are increasingly adopting Kotlin for React Native. Kotlin's concise syntax, extension functions, and null safety help write more expressive and safer code. Moreover, Kotlin's seamless interoperability with Java allows easy integration with existing Java-based libraries and frameworks, making it an excellent choice for React Native development.
Latest Kotlin Version for React Native
The latest stable version of Kotlin at the time of writing is 1.5.21. However, for React Native, the recommended version is 1.4.31 due to compatibility issues with older React Native versions. To ensure a smooth development experience, it's crucial to use the compatible Kotlin version for your React Native project.

Kotlin 1.4.31: Key Features
- Coroutines: Kotlin 1.4.31 introduces improvements to coroutines, enabling more efficient and readable asynchronous code.
- Sealed Classes: This feature allows you to express that a class has only a specific set of subtypes, enhancing code safety and maintainability.
- Improved Java Interoperability: Kotlin 1.4.31 offers better interoperability with Java, making it easier to work with Java-based libraries and frameworks.
Integrating Kotlin with React Native
To integrate Kotlin with React Native, follow these steps:
1. Set up a new React Native project
Initialize a new React Native project using the following command:
npx react-native init MyKotlinProject
2. Install required dependencies
Install the required dependencies for Kotlin and React Native:

cd MyKotlinProject npm install --save react-native-kotlin npm install --save-dev kotlin
3. Configure Kotlin
Create a new file named android/app/build.gradle and add the following configuration:
android {
...
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
}
4. Create Kotlin files
Create Kotlin files in the android/app/src/main/kotlin/com/mykotlinproject directory. For example, create a new file named MyKotlinFile.kt:
// MyKotlinFile.kt
fun greet(name: String): String {
return "Hello, $name!"
}
