Kotlin vs Flutter: Differences you must know
Authored By: Ankita Prajapati
Programming in Kotlin is simple, safe, interoperable, and modern. It offers a useful technique for creating server-side applications. Due to the fact that we can utilize our preferred frameworks and libraries with Kotlin. Although Flutter does come with some very valuable benefits like live-tracking, third-party plugins, and modular architecture, it is not the best choice for an Android application.
Read the differences between Kotlin and Flutter.
Definition
Kotlin is detailed as a statically typed programming language for the Java Virtual machine and Android while Flutter is a mobile framework that provides mobile app SDK to the developers and designers to build an app.
Scope in Backend Development
Kotlin is a programming language in itself and Flutter is a framework so we can write backend code in Kotlin language while Flutter collaborates with firebase to guarantee effective backend opportunities.

Syntax
Kotlin and flutter(DART) both are object-oriented programming languages. Flutter uses semicolons, but semicolons aren’t required in Kotlin.

Community
Flutter is a fairly new framework and Kotlin has a very stable and mature language. It is also an official language for Android app development. It is constantly evolving and has a growing global community.
Learning Curve
Kotlin’s syntax is concise and similar in syntax to other programming languages such as C, Java, Python, Ruby, JavaScript, PHP, Objective-C, Go, and Swift. If you’re coming from a Java background and want to learn Kotlin, it’s easy to pick up because Kotlin is so similar to Java. On the other hand, Flutter uses Dart, a programming language for developing cross-platform apps. Dart is developed by Google and is easy to learn if you already know programming languages like Java, C, C++, Javascript, Python, Ruby, PHP, Objective-C, Swift, Go, Rust, Kotlin, Scala, TypeScript, Elm, Haskell, Erlang, F, Clojure, and others.

UI Experience
UI is important when discussing cross-platform applications. Creating a cross-platform experience that feels natural is one of its main objectives. The same is true of Flutter. It provides consistent user interfaces across all platforms. Using a single codebase, Flutter’s UI toolkit handles every UI aspect to achieve native performance on iOS and Android. Kotlin is an open source programming language and was initially designed to create Android apps, but can also be used to build iOS apps. It offers a number of advantages over Java, including better performance and easier development.
When Kotlin is good?
It is the ideal option for beginning a new Android project or making modifications to an existing one. Regardless of the complexity or scale, it’s a really decent option for cross-platform projects.

When Flutter is good?
Flutter is a fantastic option for creating MVPs and prototyping apps. Small, medium-sized, and even large-sized corporate apps can use it. It functions best in applications like online retail, FinTech apps, and business apps where user interaction is crucial to success.

Conclusion
All frameworks and programming languages have their advantages and disadvantages, and when it comes to choosing between Flutter and Kotlin for mobile application development, they all have pros and cons. But Flutter is an excellent option for startups or businesses trying to keep the cost of developing their MVP reasonably low.
