Flutter vs Kotlin: Which framework to choose for your next

Flutter vs Kotlin

What is Flutter?

Flutter is an open-source and free-to-use software evolution kit backed by Google that allows you to make beautiful and completely native applications in a record period. Google developed and released this UI framework in May 2017.

With Flutter, you can build apps that operate on different platforms with a single codebase. This solely signifies that you can create two different apps (for Android and iOS) with a certain codebase and a particular programming language.

App development is suitable with Flutter as it lets you paint your apps in milliseconds with the Hot Reload component. Besides, you can send other attractive elements to deliver an application that contributes effectively to the end-user experience.

Use Flutter’s unmatched set of customizable widgets and layered architecture to build native interfaces and flexible designs in no time. Also, Flutter’s rich-set of widgets contain all necessary platform contrasts such as icons, scrolling, navigation, and fonts with the newly created app.

Flutter Core Features

• Hot Reload

Regarded as one of the most useful features of Flutter, the Hot Reload delivers an edge to Flutter users. Hot Reload simplifies the developer’s task for modifying and checking code without the requirement to shut down the whole application and do everything from scratch.

Also, programmers can add innovative features in the code, and Hot Reload mirrors the transformations almost instantly on the programmer’s screen.

• Cross-platform Development

Another special reason that makes flutter the best choice for developers is its ability to make an app for different platforms with a separate codebase.

You can utilize a single codebase and reuse it the number of times you like to. This protects a substantial amount of time for you. With Flutter, you can create apps for several platforms including Android, macOS, Google Fuchsia, Web, Linux, and Microsoft Windows.

• Widgets

Widgets form the most crucial part of Flutter. Widgets are the core structure blocks that create a critical part of the Dart programming language (the language used with which developers designed Flutter). With these safe building blocks, developers can compose an amazing user interface in Flutter.

• Google Firebase Support

Flutter has the support of Google Firebase, an application that helps creators build cross-platform apps. With Firebase, developers can ship some interesting components into apps reliably such as searching analytics, fixing crashes, and more.

What is Kotlin?

Kotlin is a statically typed, open-source, cross-platform programming language that is particularly designed to interoperate fully with Java and it continues to make an update with modern Java features including dynamic invocations.

Kotlin practically tries to overcome a range of drawbacks of Java, which is also considered the primary reason behind its popularity. Also, it is compatible with Java, which represents developers can use it in their existing cross-platform applications while writing server-side code in Kotlin.

It is an evolved programming language used by over sixty percent of app developers. Kotlin helps you to write better applications quickly that improve productivity, code safety, and developer satisfaction.

Kotlin Core Features

• Efficiency

Kotlin is a transparent and concise programming language with a relatively lower learning curve. It helps you to make an application with the lowest volume of code.

In terms of both coding the application and learning the language, Kotlin allows you to do things quickly. It offers better options when likened to other programming languages like Java for delivering higher-quality apps.

• Null safety

One of the most valuable aspects of Kotlin is its null safety element that every developer finds useful. NullPointerException is an aspect that every Java developer has to deal with.

While this segment explores the software quality, it pulls down the app development efficiency and speed drastically. This confuses the app development revolution.

On the other hand, Kotlin’s Null safety quality stands out by saving creators a lot of time and effort. With Kotlin, the compiler offers null safety that decreases the chance of facing runtime exceptions for developers.

• Lazy loading

The most important criterion needed for developing any application is a more rapid loading speed. And this part is looked after and supported by Kotlin’s lazy loading part.

With this part, Kotlin loads the initial content of an app quickly to decrease the start- up time, while steadily loading the other essential contents down the page. Gratitude to the lazy loading attribute, developers can now store primary and secondary resources in primary and secondary memories, respectively.

• Extensions functions

Extension functions or Standard Library Function, as named by Kotlin developers, is a component that authorizes programmers to include a new function within a prevailing class without making it difficult for them to access ready-to-use parts.

This is completed possibly with Kotlin’s extension functions that allow programmers to use these functions as extensions. You can add functions efficiently to the existing classes as extensions. Also, you can select from a wide range of standard functions and contain them within a class.

Comparison between Flutter vs Kotlin for Mobile App Development

Flutter vs Kotlin: UI Experience

Using Kotlin, UI developers can go after the application's appearance, tendency, and execution, just the way where they require it. Kotlin doesn't put any prerequisites or rules, and from now on developers can use their nearby libraries and apparatuses as opposed to creating new ones.

On the other hand, Flutter is an SDK, which mainly helps UI coordinated gadgets. It has diverse in-fabricated devices and dev conditions, which are open for the originators to use. With Flutter application result coders can make convenient flexible arrangements with a custom look and feel.

While building up an application in Kotlin, you don't have to create any UI as the developer will deal with the behavior, look, and execution of your application. As opposed to Flutter, where the application development gets you other gadgets for developing mobility solutions in a fast and tweaked way.

Flutter vs Kotlin: Performance

Flutter offers a hot reload feature that enables creators to use an individual language for both the backend and the format which makes it exceptionally easy to work with. Doing this prompts animation rate along with numerous different benefits. Flutter’s high delivery speed has fetched its five-star rating from customers.

Kotlin on the other hand operates multiplatform code that accumulates the same design that of the targeted medium and acquires the productive execution of the application.

Flutter vs Kotlin: Programming Language

Flutter utilizes Dart as its programming language, which is uncomplicated to comprehend and hence makes Flutter very suitable to work with, however, Kotlin always has to have a creator who knows Java and some other languages.

Flutter vs Kotlin: Market Popularity

Even though Flutter and Kotlin both are free and open-source tools, Flutter has more prevalence than Kotlin and its energy has rapidly chosen up. If we see it as a company visionary, we learn that Flutter has a more useful networking size than Kotlin. Flutter has 90.4k leads and 12.1k customers on GitHub whereas Kotlin has 31. k stars and 3.8k clients. Hence in the picture of prevalence, it is Flutter that wins.

Flutter vs Kotlin: Learning Curve

The availability of different Kotlin learning systems offered by Google lately and the characteristic of Kotlin to be interoperable with Java provides the platform an extra point in the comparison. However, Kotlin is a fairly new ecosystem with few resources, so Flutter is the one that wins this race.

Flutter vs Kotlin: Integration

Flutter organizes fast and viably with both Android and iOS systems. At the point when engineers are needed to set up an advanced application idea, they can use Flutter for MVP advancement. This system will give them a scope of application development accomplishment. Flutter requires the utilization of outsider instruments and libraries as it is a UI modification instrument.

Kotlin multiplatform possesses built-in tools and third-party libraries, which means you don't have to look anyplace else for the equivalent.

Flutter vs Kotlin: Learning Curve

As far as the knowledge curve is concerned Kotlin undeniably beats for it is interoperable with Java. Besides this, a few months back, Google offers several learning courses to make that scope for improvement. However, when it comes to talking about practicality, the condition is somewhat different. With Kotlin being a new ecosystem with few resources available, Flutter has the higher stand in this.

Flutter vs Kotlin: Minimum supported Platform

With Flutter, creators can make use-cases for mobile applications (Android and iOS), and web applications. In any case, Flutter doesn't support TV (tvOS), Android Auto, CarOS, or smartwatch OS. However, Application developers can use Kotlin for applications past mobile gadgets, like TV, smartwatch, etc without needing any other special characteristic.

For the growth of both the cross-stage mobile applications, both these platforms are known to be vital and perfect to decrease the time and cost of the application by advanced application execution. Even though both the systems

– Flutter vs Kotlin's ideas are good, cross-stage application development companies are relied upon to show up at their value soon.

Flutter vs Kotlin: Scope in the development

While reaching the area of Kotlin and Flutter in the backend development, it is fairly obvious that the former is ahead of the latter.

Both Kotlin and Flutter are supported by Google and are made to build mobile applications for different platforms. You can study their likenesses, dissimilarities, pros, cons, and different features and information that are given in this article to determine your platform for a customized mobile app development project.

Documentation and Community Support

Compared to Flutter, the Kotlin multi-platform is still new and still in the experimenting stage. Along these lines, the documentation and network support for the Kotlin is to some degree lagging +Flutter. However, it is normal that the documentation just as network quality will enhance once the multiplatform gets steady; further reassuring all to utilize Kotlin for cross-stage advancement.


Who is the champion in the race Flutter vs Kotlin 2022? Flutter vs Kotlin will be approximated for the foreseeable future more and more frequently. They both offer great advantages but also have some significant drawbacks.

Nowadays, in Flutter vs Kotlin, Flutter usually takes the information only because it’s better understood and comes with a bigger support group. However, it is only a point of time till Kotlin evolves the subsequent big thing.
