rysasahrialWhen developing mobile apps using Android Studio, developers often consider two powerful programming languages: Dart and Kotlin. Both have unique strengths and are backed by large tech companies — Dart by Google and Kotlin by JetBrains. Understanding the difference between Dart and Kotlin in Android Studio is crucial for making the right technology choice, especially when targeting Android or cross-platform development.’
Introduction
Kotlin has become the official language for Android development, replacing Java as the preferred option due to its conciseness and safety features. Dart, on the other hand, is the primary language used in the Flutter framework, which is also supported in Android Studio and is aimed at building cross-platform applications from a single codebase.
Below is a detailed comparison to help you evaluate Dart vs Kotlin in the context of Android Studio development.
Dart vs Kotlin: Feature Comparison
| Feature | Dart | Kotlin |
|---|---|---|
| Main Use Case | Cross-platform (Flutter) | Native Android development |
| Developed By | JetBrains (backed by Google) | |
| First Released | 2011 | 2011 |
| Android Studio Support | Via Flutter plugin | Full native support |
| Syntax Style | C-style, modern and simple | Similar to Java, concise |
| Performance | Excellent via native compilation (Flutter) | Excellent, native performance |
| UI Toolkit | Flutter’s widget system | Android Jetpack / XML |
| Learning Curve | Moderate for Flutter newbies | Easier for Java developers |
| Community & Libraries | Growing rapidly with Flutter ecosystem | Mature with rich Android library support |
| Web/Desktop Support | Yes (Flutter Web, Flutter Desktop) | Limited (via Kotlin Multiplatform) |
Dart in Android Studio
Dart is primarily used within Flutter, which allows developers to create apps for Android, iOS, Web, and Desktop using a single codebase. Android Studio supports Dart through the Flutter plugin, enabling hot reload, widget tree debugging, and performance profiling. Flutter’s reactive framework, built in Dart, makes UI development fast and expressive.
With Dart and Flutter, the UI is drawn directly using Skia graphics, which makes it consistent across platforms. Dart compiles ahead-of-time (AOT) into native code, ensuring high performance for mobile apps.

Kotlin in Android Studio
Kotlin integrates natively into Android Studio without the need for any additional plugins. It supports Android Jetpack components, modern Android APIs, and is fully interoperable with Java. Kotlin’s syntax is expressive and concise, allowing developers to write safer code with fewer lines.
Google recommends Kotlin for all new Android development projects. It supports coroutines for asynchronous programming and has excellent support for dependency injection libraries, Jetpack Compose (declarative UI toolkit), and more.
Kotlin is a better fit for teams focused exclusively on Android and who want to leverage the latest Android APIs without the overhead of managing cross-platform concerns.
Which Should You Use?
- Use Dart + Flutter if:
- You want to build apps for both Android and iOS with one codebase.
- You prefer a highly customizable UI framework.
- Your team is open to learning a new toolkit for faster cross-platform development.
- Use Kotlin if:
- You are building an app specifically for Android.
- You want full access to Android’s native features.
- Your team has a Java background or existing Android experience.
Conclusion
Choosing between Dart and Kotlin in Android Studio depends on your project goals. Dart with Flutter excels at cross-platform development, while Kotlin provides a mature, native Android experience. Both are modern, safe, and performant — but each serves different needs.
In summary, Dart is your go-to for cross-platform apps, while Kotlin is ideal for robust Android-native applications.
