Should I learn Kotlin or Flutter


Flutter is a great one cross-platform framework, with which one can build applications for mobile, desktop and web platforms. Google officially published it in December 2018. Barely a year later, it had already overtaken React Native in terms of popularity - both on GitHub and on Stack Overflow. What's behind all the hype? Do you really need something like Flutter? We think: yes! Why? That explains this article.

Why a new framework?

One of the most common questions asked when it comes to Flutter is, "Why should I use Flutter instead of React Native or any other software development kit (SDK)?" and the answer is simple: it's better than any other cross-platform framework out there in every way. Understandably, people usually want a more detailed explanation.

Often times, we have become so used to how our tools and resources work that we can no longer see their limits. Only when someone comes up with something better do we notice how awkward we work - and how much easier it could be! And even then, our prejudices or habits can make us shy away from trying something more powerful, more flexible. It's the same with software.

Example: Someone with only PHP experience will argue that PHP is a great language. At the same time, he will not understand the vast ecosystem of devices and systems beyond simple web servers. But not everything is a website. It is for this very reason that we advocate tools created specifically for app development instead of adopting tools from the front-end web ecosystem.

Benefits of flutter

Flutter has some distinct advantages over the alternatives. The underlying language and the SDK are developed in such a way that they avoid typical problems and weaknesses of other technologies. In the following you will find a few important reasons why you should implement your next project with Flutter:

The dart language

Many other languages ​​have struggled (or are still) struggling to standardize. They have many different versions with different language characteristics - many developers don't even know what these differences are.

In contrast, darts is designed and optimized from the start to create client applications - with special attention to the user interface (UI). There are no competing standards, no grafting of standard functions, and no strange language peculiarities.

In short: darts has one clean and incredibly powerful syntax. Not only does it facilitate strong app architecture and app design, it also promotes it. To be added Team merging, standardization, longevity, serviceability and other thingsthat are often missing from previous cross-platform tools.

Dart is similar to other popular languages ​​such as C #, Java, and TypeScript. This means: developers with the appropriate experience can easily find their way around and use darts immediately.

Strong acceptance in the developer community

Within just under a year, Flutter became more popular on both GitHub and Stack Overflow than React Native, which was the most popular cross-platform framework at the time. There is already one accordingly large pool of resources, many skilled developers, and faster iterations of the technology itself. That means: the technology develops and matures faster and remains relevant longer. All of this benefits your app when you develop it with Flutter.

In the graph above from Stack Overflow Trends, you can see Flutter emerge from nowhere and take the lead. That will likely continue. Sooner or later it could become more difficult to convince developers to support cross-platform applications with other technologies. This process often takes a long time, probably several years, but it has happened again and again within the software developer community.

Flutter is extremely fast

Flutter applications can be compiled into native binary files that rely on graphics and rendering engines created in C / C ++. This creates a very fast and high-performance application. Flutter applications are able to achieve a stable 60 fps on most devices. On supporting devices it is even an unbelievable 120 fps.

A driving factor behind the rapid spread of Flutter is that many mobile application developers are using it tremendous performance improvement compared to other cross-platform frameworks.

While it's true that developing truly native applications is hard to beat for performance and smooth playback, when it comes to cross-platform frameworks, Flutter has clear advantages over the competition.

Flutter is (relatively) easy to learn

Sure: there is no real production language or toolkit really easy to learn. But there is a big difference between those with clear documentation and standard design patterns that work for a large number of use cases, and those with incomplete documentation and very different ways of actually doing very simple and uncomplicated tasks.

These excellent documentation von Flutter and the large number of high quality reference examples are another reason for the widespread use of Flutter in addition to the performance. This makes a big difference for developers who want to learn a new framework, toolkit, or a new language. This is especially true for experienced programmers who can identify problems with the design of a language or toolkit on their own.

Someone who has programmed for decades will quickly become frustrated when they encounter poor documentation or conflicting standard design patterns.

Experts and beginners appreciate Flutter for its clear documentation and the supportive community. They are very willing to share their experiences and provide solid, working examples of great design and development patterns that others can benefit from. There is no trace of elitist thinking.

Flutter is well thought out

Google developed Flutter on the basis of an excellent language (Dart) and a fast, high-performance rendering engine (Skia). These design decisions avoid years of experimentation at the expense of others. The result is an outstanding framework. Conflicts of standards or built-in technical debts do not play a role here, Flutter encourages developers of all skill levels to good design patterns and best practices to use in their applications.

Anyone who has developed applications for a wide variety of devices for many years will likely see the clear benefits the program offers within minutes of working with Flutter. And beginners will be spared a lot of frustration as there are great examples on the internet from which they can learn.

UX for Android and iOS in one

An app for iOS and Android - that is the great promise of crossplatform development. If only it weren't for the UX! Because iOS and Android differ in look and feel: what can produce an excellent user experience on one platform always feels a bit strange on the other.

Flutter has found a great solution for this by making certain things for iOS and Android automatically represents differently. Scrolling lists, navigating and much more feel to the user as they are used to from their operating system. The developer can sit back and relax and let his SDK do the work for you.

Full stack development in the future?

The web support announced by Google will be a particularly big win for the future. This means that backend and websites could also be written with Flutter in the future, so that full stack development is within reach.


Redesigned from the ground up to enable high-performance applications to be built in record time, Flutter avoids many problems. How many can hardly be put into words. Flutter offers an excellent development platform that is must-see. To know it is to love it.
