In 2015 there was no Flutter, but there was a so-called browser war. Developers of Chrome were thinking about how to optimize their browsers. This led to the team deciding to cut CSS out of the browser engine — which showed a very big increase in performance.
Realizing that it must be somehow used grew into what we call Flutter now. In our article, we will cover topics such as what Flutter is and when and how to use it for building beautiful applications in a short time.
Flutter was introduced by Google as an open-source technology for coding and creating native apps for Android and iOS. Flutter is relatively new as it was officially presented in December 2018 as the first stable version 1.0 at the Flutter Live event.
Google uses Flutter for various Google Assistant modules and the Google Home Hub user interface. Moreover, there are already 50,000 Flutter apps available in the Google Play Store, and this number is increasing at a high rate. Alibaba Group, eBay, Groupon, and other popular e-commerce providers use Flutter as well to give their web and mobile applications uniform looks.
Tim Sneath, Group Product Manager at Google, says, “Our vision for Flutter is something that many of us have been dreaming of for years — a powerful, general-purpose, open UI toolkit for building stunning experiences on any device-embedded, mobile, desktop or beyond”.
The framework of Flutter, written in the Dart programming language, has the Flutter engine, Foundation library, and widgets. The approach to development in Flutter differs from others by its declarative UI writing. Here, there is a need to start from the end, meaning before starting the development of some element, the user needs to have in mind a complete picture of what kind of UI it will be. Many developers distinguish this UI writing as a more clear one, but it also causes certain difficulties for developers at first.
The main idea of Flutter is that developers can build the entire user interface by simply combining different widgets. The application interface consists of various nested widgets, which can be any object. This applies to anything from buttons to padding, and by combining widgets, the developer can customize the application radically. Widgets can influence each other and use built-in functions to respond to external changes in the state. Widgets are important elements of the user interface and comply with the design specifications of Android, iOS and conventional web applications.
With Flutter, developers can create custom widgets, which can be easily combined with existing ones. Note that there are no OEM widgets, but Flutter Gallery provides developers with their own ready-made widgets — a set of application examples that show how to use standard widgets — which look like native Android and iOS design languages (Material and Cupertino).
When it comes to developing applications, developers are not restricted to a single cross-platform mobile framework. In fact, statistics show that while the majority of developers use React Native (42%), Flutter usage in 2020 (39%) has highly grown in comparison with Flutter usage in 2019 (30%).
Let’s take a closer look at explaining why Flutter application development can be a better choice.
Flutter creators wanted to invent a technology with the quickest opportunity to deliver a great-performing, cross-platform mobile application. The following features allow this:
Hot Reload Operation
Flutter helps make developers’ lives easier through its third-party integrations and native codebase. With Flutter, developers can access native features.
That’s what makes quick code development possible, thus the whole process faster, easier and less disturbing.
Will Larche, Software Engineer at Google, says, “Flutter’s architecture is designed for building beautiful, custom UI. Flutter’s main goal is to make building polished, custom app interfaces a faster, more delightful experience for designers and developers. Flutter is powerful enough to draw anything designers dream up.”
Reflectly App Attractive Design Made on Flutter
Flutter doesn’t need any platform-specific UI components to render its UI. The one and only thing Flutter needs to show the application UI is a canvas to draw on. It can be illustrated the following way:
There are things that are of great value to the business — platform stability, its performance, a guarantee of successful support, and improvement of technologies and products. Any problems and shortcomings in any of these aspects may lead to risks, including direct and indirect financial losses.
With this in mind, Flutter lowers risks for your business due to the following points:
A good UX is incredibly dependent on the performance of the application. Flutter application performance in most cases will be indistinguishable from the native application. This is because Flutter doesn’t rely on intermediate code representations or interpretation. Application on Flutter is compiled directly into machine code, eliminating any performance errors in the interpretation process. This provides it with the highest performance and makes it the most resource saving software among cross-platform technologies.
Also, finding Flutter engineers in 2020 is not a problem — the community of fans is growing, especially among Android developers. According to Stack Overflow Developer Survey 2020, 68.8% of developers — which is among the top 3 — love to use Flutter and have expressed interest in continuing to develop with it.
“Getting started with Flutter was truly awesome. The huge power and productivity you get with instant stateful Hot Reload was mind-blowing,” says Jacob Kristensen, Co-Founder of Reflectly.
While Flutter has a lot of benefits that businesses can take advantage of, there are some areas in which it still needs work.
If you define Flutter as your solution after reading the material above, check through the points when Flutter perhaps should not be your choice if you are:
Although Flutter is young enough, it is already used by such global services as Google Ads, Alibaba, AppTree, Reflectly and many others.
“Flutter significantly reduced the time we need to develop new features from 1 month down to 2 weeks.” says Bruce Chen, Senior Development Engineer, Alibaba.
Flutter has also been picked as the solution for Nubank for all app development. Nubank is the largest digital bank in the world outside of Asia. With over 20 million customers, they could easily see the benefits of unified app development.
As for the question, “What apps can be made with Flutter?”, the answer is quick and simple — any. You can develop applications for any purpose — from small business (online stores, banks) to large ones (contact centers, courier control, organization of internal processes). However, Flutter is the best option for start-ups and R&D projects, primarily because of the ability to quickly prototype and check business ideas.
The NIX team also has experienced cases on Flutter, so let us showcase one case of NIX’s expertise in Flutter development — Meeting Room Booking App:
The client — a large enterprise with about 2,000 employees offering insurance services — had a web version that required an update and approached NIX to create a co-working space management app for iOS and Android with minimal cost expenses. We proposed a cross-platform solution that will cover both the client’s and users’ needs.
After two months, the client received multifunctional booking and scheduling software for co-working spaces.

Flutter’s popularity is easy to understand, and while half a million developers use Flutter monthly, the top five territories for Flutter developers are the US, China, India, Brazil, and the EU.
“You see today, how Flutter is already enabling developers all over the world to deliver beautiful apps to hundreds of millions of people throughout the globe. But this is also just the beginning.“ says Eric Seidel, Engineering Manager at Google. “Flutter is highly portable and already works on many form factors beyond phones… So if I look forward a few years, I see Flutter running in a ton more places.”
A technical preview of Flutter Web was introduced by Google, which allows developers to run Flutter applications in a browser in a clean form without changing the source code. It means that with Flutter, developers can 100% go further beyond app development on mobile. Moreover, this marks Flutter’s transition from a cross-platform mobile application framework to a full-blown cross-platform development tool. However, for now, NIX experts see in Flutter web development more difficulties, since it takes a lot of time to get the correct display of elements and the operation of the application from a single base. We are looking forward to new web updates.
Despite the fact that everything, except the mobile part of the framework, is not yet considered ready for production, an experienced Flutter developer can make a pure flutter application, running today on any major platform — including Android, iOS, Web browser, Windows, macOS, Linux and even embedded devices — and the application will function properly without changing and customizing the code for each platform separately.
While Flutter is new, its creators are not resting on their laurels. They are continually innovating and improving Flutter to make it a more useful and powerful tool for developers. Some key improvements that are worth calling out in 2020 are as follows:
