What Is Flutter?

Flutter is an open-source framework created by Google for building user interfaces for web and desktop applications as well as mobile apps that run across iOS and Android platforms. In contrast to most cross-platform development frameworks, Flutter doesn’t use web technologies such as JavaScript or WebView. Programmers write apps with the Dart programming language.

Flutter is a young and fast-growing technology that has recently become the center of attention of various companies. Google presented the first version of Flutter in 2015 with the two main goals:

  • to replace the traditional layout model used in cross-platform development on the whole;
  • to increase the app rendering speed from 60 to 120 FPS.

Back in 2015, Flutter had a codename Sky and ran apps only on the Android OS. By the end of 2018, the company launched the stable version of the framework. Now, it allows rendering some apps with the stated 120 FPS speed and running them on both iOS and Android platforms. The Flutter SDK is also the only toolkit used for developing apps running on Google Fuchsia OS. In 2019, thousands of people started to actively use the apps made with this technology. Our list of top 10 apps built with Flutter will help you understand how developers create UIs with this technology and make it attractive for users.

Top 10 Apps Made with Flutter

Using Flutter, developers can create simplistic applications with interactive multimedia support. They usually are 2D apps with high-performance animations and simple mobile games. Programmers can also develop full-featured applications able to easily access device capabilities (such as storage, network, camera, geolocation, third-party tools, etc.). The types of applications powered with Flutter mostly include:

  • Apps using Business Intelligence tools;
  • Banking apps;
  • Credit card managers;
  • Wallets and money exchange systems;
  • 2D games (puzzles, doodles, etc.);
  • Social media aggregators;
  • Audio, video, and photo editors;
  • Tracking applications;
  • Markenline shopping apps;
  • News aggregators;
  • Task managers;
  • Music players, and so forth.

Although it’s been only a year since Google Flutter appearance, the apps created with this framework are already on top positions in different categories on Google Play and App Store. To understand how companies currently use the framework in their products, let’s make a review of the 10 most interesting apps built with Flutter. The applications for this top were chosen from the official Flutter showcase page and the additional resource provided by the Flutter community “It’s All Widgets!”.

The platform also offers the Social Splash feature for monitoring every social channel, check business performance and view the competitors’ performance.

Benefits of Flutter Framework

When developing Flutter, Google aimed at replacing traditional cross-platform app architecture with the simpler one and using Dart as a single language for coding to enable the Ahead-of-Time (AoT) compilation. The AoT compiling makes it possible to dynamically execute binary files in a native manner. The company successfully achieved this aim, which made the framework beneficial for entrepreneurs and convenient for developers. Thus, the advantages of Flutter are:

  • Cross-platform development. The ability to build apps running on both Android and iOS is an undeniable advantage of Flutter. With this solution, business owners don’t have to control two separate teams that specialize in building an app for two platforms. One team is enough to create a cross-platform app with Flutter, which means you can cut costs and save time.
  • Native Feel and Performance. The Skia 2D graphics library helps developers create fast-responsive apps with neat glitch-free graphics at the native speed of a mobile device. The Dart language enables compilation to binary code, which allows reaching the operational speed just like that of the native languages of iOS (Objective-C or Swift) and Android (Java or Kotlin).
  • Faster development cycles. Sometimes, the development process can be slow because programmers must compile the entire application every time they change it. With Flutter, a developer can save the app’s state and update it in less than a second with hot reload. This feature allows adding the updated files to the Dart Virtual Machine (VM) and, as the VM reloads, the framework rebuilds all widgets automatically.
  • User-friendly and eye-pleasing UI. Android and iOS differ by the element layouts, so it can be difficult for a developer to create the same look of an app for both operating systems. With Flutter, a developer can make apps UIs look the same with the layered structure and pixel-perfect rendering of the UI elements.
  • Customizable widgets. Flutter doesn’t use native components. That means that a developer doesn’t need to use a bridge to provide communication between the native UI and code thread. A set of Flutter widgets includes Material Design elements for Android apps and the Cupertino library that helps implement specific design components for the iOS platform. Any element – be it a button, text, background, or media – is drawn only with Flutter capabilities.
  • Easy integration into an existing app. A development team can add the Flutter packages or use its module template as a library in the existing codebase. This enables the team to improve native or non-native apps with new UI components and functions like it was with the Groupon Merchant application.

Disadvantages of Flutter

It’s been only a year since programmers started to use Flutter capabilities in full, so there’s no surprise that the framework has its flaws. They include:

  • Young technology. Since this technology is relatively new, some companies fairly distrust it. Still, the technology matures rapidly and has a high potential to win the entire market in a couple of years.
  • Small developer community. Since the Flutter community has just started to grow, the framework has only basic libraries that help with app creation. There’s a need for engaging more people in Flutter app development to share their experience and provide additional packages and libraries for solving specific problems.
  • Need for learning the new language. Many cross-platform technologies use JavaScript, so switching from Apache Cordova to React Native, for example, would be easier because they use the same programming language. Since Flutter doesn’t use JavaScript, it’s obligatory for a developer to learn Dart. However, Google states that Dart is understandable and intuitive.

Conclusion

Flutter provides developers with a wide range of built-in tools that help them create apps faster and easier. It has a unique architecture, offers a powerful pixel-perfect rendering engine, and doesn’t use any traditional web technologies. The Dart language makes it possible to build simplistic 2D applications and games with high-performance animations. Flutter-powered apps stay simple but are able to handle great loads of multimedia and provide easy access to device features.

Despite all the advantages of Flutter, there are two groups of people that have different attitudes towards it. The first group wants to try this technology because they like the idea of Dart and a faster rendering engine. Others mistrust this technology because they think it has yet to mature. What group to select for yourself is up to you.
