Dart vs Kotlin

Both Dart and Kotlin are popular programming languages that can build mobile applications. This Dart vs Kotlin blog discusses syntactical and ecosystem differences between Dart and Kotlin and provides you with information for choosing any one of these two programming languages.  

For developing any kind of application, we use programming languages. Among various programming languages, Dart and Kotlin are gaining massive popularity over the recent years. Dart is a programming language used by Flutter to create beautiful, rapid, and compiled applications for desktop, web, and mobile. Kotlin is an object-oriented, open-source, and general-purpose programming language.

Due to variations in their features and working approaches, we can use Dart and Kotlin for developing different kinds of applications. In this Dart vs Kotlin blog, we will compare Dart and Kotlin based on different parameters.

What is Dart?

Google created Dart to help developers create better client apps and make the development process more manageable. It has maintained its reputation as a technology since then. Numerous visionaries have been able to present the world with apps that provide a unique experience. In the second half of this article, we'll discuss Dart-based apps.

What is Kotlin?

JetBrains, one of the most well-known IT companies, created Kotlin. It was created in response to their need for a less complicated language than Java. Kotlin has climbed to become one of the world's most popular languages. Google declared it the recommended language for Android app developers in 2019.

Commercial Comparison between Dart and Kotlin

  • Popularity

    Popularity indicates the level of enthusiasm amongst customers and developers, and it can be used as one of the factors in deciding which programming language to use. Because of its popularity among developers, it will be cheaper to recruit developers, and because of the interest from clients, it will appeal to businesses.
    Dart is tagged in over 1.2% of questions on Stackoverflow, while Kotlin is labelled in over 1% of queries that month. Nonetheless, there has been a growing interest in both languages. A Stackoverflow Trend Chart can be found here:

    According to the Google Trends graph below, Google users were more interested in Dart than Kotlin over the last year:
    Google Trends Comparison between Dart and Kotlin
    What do Dart and Kotlin developers think? Kotlin is utilised by 7.8 percent of respondents in the Stack Overflow Developer Survey 2020, while Dart is used by 4%. Both languages, however, are among the most popular, with Kotlin coming in fourth (62.9%) and Dart coming in seventh (62.1%), respectively.
  • Market Share

    When it comes to market share analysis, it's more customary to compare Flutter with Kotlin because Dart is used with the Flutter framework. The market share statistics for the two technologies are compared below:

  • Learning Curve

    The training is critical for developers when determining whether or not to begin learning a programming language, and it's also critical for customers while assembling team members: the simpler the language is to understand, the simpler it is to recruit the necessary expertise. Because of Google's extensive documentation, Kotlin is simple to learn, although the current focus is on Kotlin Multiplatform, which has fewer resources than Flutter and Dart. Still, it's only time with Kotlin's introduction of multiplatform support over a year ago.

  • App Development Costs

    Because Dart and Kotlin are both open-source, you can gain unrestricted access to the source code and the documentation you'll need to get started. They also provide a quick way to construct an MVP because both Android and iOS apps can be created and maintained from a single codebase, reducing expenses by eliminating the need to operate two different source codes and hiring developers to build two versions for two different operating systems. Previously, Kotlin was only accessible for developing Android apps; however, with the launch of the Kotlin Multiplatform Mobile platform, it now supports cross-platform mobile development.

  • Pricing

    The significance of pricing is crucial. In addition to developers, businesses and individuals are looking for technology comparisons to construct their business apps. Flutter apps are popular, and as a result, there are a lot of rivalries. As a result, clients can afford them thanks to the low price. With a Dart, you can build a multi-platform app for under 20,000$ for simple apps, 30,000$ for medium apps, and 45,000$ for large futuristic advanced tiered apps.

    The Kotlin language, on the other hand, maybe used to create both native and cross-platform programs (Kotlin Native) (Kotlin Multiplatform). The basic price for native will be 35000$ (simple) to 80000$ (advanced), while cross-platform will be 25000$ (simple) to 55000$ (advanced) (advance).

  • Cross-platform Support

    Flutter and Dart have already made a name for themselves in the cross-platform world and love their outstanding performance and native support.

    "Support for multiplatform development is one of Kotlin's primary strengths," according to the project's authors. It saves time by decreasing the effort involved in developing and updating the same code across platforms while maintaining flexibility and advantages of native programming."

    When it comes to cross-platform programming, speed is crucial. Flutter's performance is excellent because of the Hot Reload feature, which allows you to alter the code and see the results right away. Still, Kotlin's performance is excellent because of the code's architecture and testability.

    There is no definitive answer to which programming language to choose for cross-platform app dev.

    On the other hand, Flutter appears to be an excellent low-cost language for entrepreneurs, allowing them to construct many apps with a single codebase. If you have any Java code that can be translated to Dart, Kotlin is the best choice.

Are Dart and Kotlin Similar or Different?

When comparing several technical qualities, they are pretty similar, yet there are some discrepancies. So, how do they compare? Here are a few instances that show what we mean:

  • When comparing the syntax of Kotlin and Dart, they are more comparable to some extent.
  • When it comes to composing comments and dealing with white spaces, both languages follow the same rules.
  • Object-Oriented Programming Languages (OOP) include Dart and Kotlin.
  • Dart and Kotlin are both statically typed programming languages, which implies that their set of rules assures that all pieces work together consistently. Dart is still using Kotlin's null safety in BETA.
