    Why Use Flutter for Web App Development

    Google has recently released Flutter 3.0, a new version of the framework chosen by thousands of developers all over the world and successful businesses. It inspired us with features, significantly simplifying and speeding up the process of creating IT-products, so we decided to describe 8 reasons to use Flutter for web app development.

    At Surf, we have implemented more than 15 Flutter-powered projects. Our developers know everything about the framework: they hold conferences and podcasts, create open-source tools, and test existing ones. We have in-house projects to test its new features before using them for clients’ projects. In this article we share proven expertise—so read it until the very end, and you’ll find the most up-to-date information on the matter.

    Using Flutter for web apps: powerful technical solutions for developers

    Here are the main benefits Flutter offers for web development.

    High performance

    The first thing that makes Flutter good to use in web development is great performance on a par with native technologies. It stays high even if you need to create a web app with complicated visual effects.

    Flutter has its own graphics engine with optimization comparable to native ones. Images change at a speed of up to 60 FPS, which is more than enough for most services. Moreover, in Flutter 3.0 you can build user experiences for 120 Hz ProMotion displays. And faster animations, such as scrolling, feel smoother.

    Flutter shows perfect results in apps that have typical processes and logic, without any extra requirements. Requests to the server, working with files, and the APIs — all these things are implemented asynchronously and do not degrade performance.

    Flutter uses the programming language Dart and a virtual machine created specially for this language, DartVM. It allows us to compile the language with AOT (Ahead-of-time) or JIT (Just-in-time) compilation. Interpretation or compilation into other languages is common for this one as well.

    As a result, developers get the Hot Reload, a feature that helps load the code into the app in debug mode instantly and without loss of state. The development process incredibly speeds up, and IT specialists do not have to rebuild the app every time to review every change. In the release, the program gets high performance thanks to AOT-compilation.

    Easy code maintenance

    Dart is an easy language, especially for developers writing in Java, C#, or JavaScript. Skilled developers need about 2 weeks to master it and start to use Flutter for creating web applications, while new specialists need about 3-4 weeks for it. Besides, several days is usually enough to learn Dart’s syntax. The programming language was designed to make the development process and onboarding fast and comfortable.

    The easier the language is, the easier code maintenance is. Developers can onboard to the working process in a short period of time, and after that they write the code, correct it, and make tests without any extra help from teammates.

    Great architecture solutions

    The framework has simple, modern architecture providing businesses with an opportunity to release MVP as fast as possible. It’s a great choice if you need to present your Flutter web app to investors, and not only.

    Toolset for web development

    The toolset offered by Flutter is useful and effective. Choosing Flutter, you will be surprised how convenient the process is, and what new features the 3.0 version has delivered.

    One of the important features updated recently is image decoding. Flutter began to automatically detect and use the ImageDecoder API in browsers that support it. Now, most Chromium-based browsers (Chrome, Edge, Opera, Samsung Browser, etc.) have added this API.

    The new API decodes images from the main stream asynchronously using the browser’s built-in image codecs, so the image decoding is 2 times faster and does not block the main thread. It helps to avoid lags when loading images.

    The second important feature is web application Lifecycle API. With it, you’ll have more control over an initial load of a web app using Flutter from a server-side HTML page. In addition, the feature makes it easier to analyze the performance of your app in Lighthouse.

    Welcoming and active community 

    According to Statista, Flutter is the most popular cross-platform framework. Flutter enthusiasts from all over the world join the community to develop the framework, create new open-source tools, organize and attend meetups with 60k specialists involved, actively participating in them. 

    Surf isn’t an exception. We have a strong Flutter team participating in world-famous projects: our developers use Flutter to build web and mobile products for various niches including fintech, foodtech, and entertainment industry.

    To optimize Flutter development, we developed Surf Gear, a set of libraries and tools and are glad to share it with the community. Our solutions have been gaining popularity among developers from various countries. And we continue to use Surf Gear in all our Flutter projects, supporting and upgrading its tools.

    Why do businesses choose Flutter for web applications?

    Now, let’s overview some case studies when companies have used Flutter for their projects.

    Supernova case study

    Supernova chose Flutter for their collaborative design system platform. It is a compute-heavy tool, requiring high performance. With Flutter, they tried the lower-layer rendering and got excellent results.

    Rive website

    The Rive was searching for a tool able to handle heavy graphics rendering across different browsers and platforms and help them reduce development cycle management time. Having chosen Flutter, they get easier maintenance of the codebase, deliver richer experiences, and simplify a process of adding custom things. 

    iRobot expands access to coding

    iRobot wrote production code with Flutter for the time it could be spent on writing the original iOS app and released a multiplatform version of the iRobot Coding App on Android, iOS, and web. By today, the iRobot Coding App has expanded to three major platforms and 170 countries with thousands of active users.

    Flutter for web apps: promising perspectives for business

    Flutter is a prospective technology. Read further to learn why. 

    Time and cost efficiency

    Flutter helps businesses save time and money. As the framework is cross-platform, you need less specialists and less time for launching and developing an MVP. The same codebase is written for various platforms and adopted for each of them. As a result, depending on the project specific nature, you can save about 40% on app creation.

    At Surf, we had the experience of building a single Flutter app for 3 brands of a pharmacy chain—it took us less than 4 months and allowed us to save 40% of the budget that would otherwise be spent with native technologies. Read the full story to find out more about the results.

    Proven quality supported by Google

    Flutter and Dart were developed by Google, and they are actively used by the tech giant for projects like Ads, Fuchsia, and Google Pay. Many other companies, such as BMW, Alibaba Group, Nubank, and Toyota trust Flutter to develop their applications.

    Enthusiastic Flutter app developers to hire

    Teams of Flutter enthusiasts grow together with the technology and know all the possible details and fine points, so they know how to implement each feature you wish to see in your Flutter-powered app, and do it fast and with high quality. 

    However, the technology is young, and choosing a qualified developer team, able to use all the advantages of this framework, is a challenge. So, it’s important to pay much attention to this factor.
