Will Developing Flutter Plugins in Kotlin Make a Difference Compared to Java?

As it stands, many in the Flutter community ponder the question of whether developing a Flutter plugin using Kotlin holds any significant advantage over the more traditional Java approach. This inquiry is fueled by a combination of personal preference and the desire for efficiency in coding.

In this guide, we’ll break down the insights into the development environment for Flutter plugins, specifically focusing on Kotlin versus Java, and what it means for developers aiming to create and share their own plugins on pub.dev.

The Current State of Flutter Plugins

Flutter, a UI toolkit created by Google for building natively compiled applications, predominantly uses Java for Android and Objective-C for iOS as the back-end programming languages for plugins. However, recent updates have made Kotlin and Swift the default languages, respectively, for new Flutter projects. This advancement raises the question: Is it worthwhile for developers to embrace Kotlin when writing plugins?

Understanding the Advantages of Kotlin

Many developers gravitate towards Kotlin over Java for several reasons:

Cleaner Syntax: Kotlin reduces boilerplate code, leading to more concise and manageable codebases.

Null Safety: Kotlin's type system helps mitigate null pointer exceptions, a common pitfall in Java.

Immutable Collections: It encourages using immutable data structures, improving safety and reducing unintended side effects.

Creating a Kotlin-based Flutter Plugin

If you decide to create a plugin using Kotlin, here’s what you need to know:

No Extra Configuration Needed: Modern Flutter projects come pre-configured to support Kotlin. This essentially means that if you’re using a current version of Flutter, your plugin written in Kotlin won’t impose additional configuration requirements on Flutter developers utilizing your plugin.

Compatibility Across the Board: Even if a developer’s app was originally configured with Java, they will not face compatibility issues using a Kotlin-based plugin, provided they are on a reasonable version of Flutter. The native plugin code is transformed into a Gradle dependency, which keeps it seamless for developers using your plugin.

What About iOS Plugins in Swift?

The same principles apply when considering iOS plugins developed in Swift instead of Objective-C. Insisting on Swift aligns well with the modern iOS development practices, just as Kotlin does for Android. Here’s what to consider regarding iOS:

Current Standards: Swift has become the standard programming language for iOS development, emphasizing clarity and efficiency.

No Compatibility Issues: As with Android, using Swift for iOS plugins won’t cause incompatibility with Objective-C based projects, provided the iOS configurations are updated.

Conclusion

Developing a Flutter plugin in Kotlin (or Swift for iOS) is not only a sound choice for personal preference but is also aligned with the best practices in the current Flutter ecosystem. Embracing these languages ensures cleaner code and modern language features while maintaining compatibility across different project setups.

With the transition toward Kotlin and Swift as the default languages in Flutter, you can build your plugin without concerns about compatibility or additional configurations. Your innovative solutions can smoothly integrate into various Flutter applications, paving the way for a robust plugin ecosystem.

So, go ahead and develop that Kotlin-based Flutter plugin! Your personal preference can unlock new avenues for efficiency and clarity in coding.
