The popularity of cross-platform applications is constantly growing. In recent years there has been a lot of buzz around React Native and Flutter. Everyone seems to be talking about apps using those particular technologies. For most developers, they are still a bit “exotic”. That’s why, after writing our article about React Native apps, we decided to take a closer look at mobile apps in Flutter.

What is Flutter?
Flutter is a cross-platform framework that uses just one code to create apps for different devices. Applications that are programmed in Dart language act almost identically on each mobile operating platform (Android & iOS) and they have similar efficiency to their native solutions. Moreover, apps made with Flutter are indeed native.
Using Flutter is justified in many cases when it comes to mobile apps because it has several benefits. A hot-reload function allows developers to introduce changes in almost real-time. Material design widgets in Flutter are used to create visually impressive mobile apps. This open-source framework is praised for splendid performance, logical architecture and thorough documentation. Flutter is often recommended as a cross-platform tool for building iOS and Android apps because working with it is productive and effective.
What is Dart?
Dart is an open-source, object-oriented and multi-platform programming language created by Google and released in 2011. Its universal nature and robust capabilities made it one of the mainstream tools for building mobile apps, but also web and desktop software. Apps created with Flutter are coded in Dart. This language can compile both in AOT and JIT, which gives developers’ a choice when building Flutter apps.
JIT compilation (just-in-time)
For when you want to compile while developing the app to enable hot reloads.
AOT compilation (ahead-of-time)
For when you have finished development and the product is ready for release. It helps with fast startup and better execution of the app.
Why brands pick Flutter?
Dart and Flutter were used in big projects by influential brands – you will find it in Google Ads, eBay, BMW, Tencent, Groupon and so much more. In this article, we are sharing the details of all the well-known mobile apps we use daily that are made with Flutter.
But you might wonder why big corporations would even bother with using a cross-platform technology like Flutter? Well, its convenience is undeniable. Having applications that can share the majority of their code allows developers to introduce changes and update them within seconds quickly. Also, Flutter has a stunning UI that provides almost a native-like feeling, so if any project team can save time and resources on development and achieve similar results – why not try?
Apps made with Flutter
Here is a list of brands that have their own Flutter app or even several apps for powering their primary services. We take a closer look at the app development process and implementation to determine how established worldwide famous companies took advantage of material design, hot reloads and other robust functionalities of Flutter.
Google products – Stadia, Google Ads, Google Assistant
Google Stadia is a streaming platform for gamers. This service is available on mobile devices, both Android and iOS. On November 18th, 2019, UI Engineering Lead confirmed that the Stadia app was built using the Flutter SDK. The Stadia team decided to use this technology during the prototyping stage of the project.
Flutter received support a while ago and now it makes it possible to code apps for other platforms – like web and desktop. But Stadia developers acknowledged that for the implementation time of Stadia, only mobile apps are using Flutter. Nonetheless, this is proof for devs from all around the world that they should give this framework a chance. Not only did Google create it for themselves, but they also use it in their products.
Flutter is also used in the mobile app for Google Ads management. Unlike a previous application, the new Google Ads app offers better insight, campaign management alerts and editing current campaigns. It also allows Google experts to be contacted through it.
Flutter also helps power an ever-growing number of Google Assistant apps.
Reflectly is an example of an app that was created in React Native at the beginning. The team programmed it for iOS using this technology. When they decided to introduce the Android app – a problem occurred. Because of the enormous popularity of the app, in 2018, they decided to rewrite it altogether. They chose Flutter, which was perfect for this purpose. In 2 months, they rewrote their app and made it available for both Android and iOS. The new version was shared in May 2019.
“Using Firebase Analytics and Sentry, we meticulously monitored the release for any unforeseen issues as it was being deployed to new and old users. Despite Flutter’s beta label, we did not, and have not, seen any major issues using Flutter in production across hundreds of thousands of users, running on a multitude of different iOS and Android devices.” ~ says Daniel Vestergaard, Co-founder & CTO at Reflectly.
Alibaba Group used Flutter in the Xianyu app
A development team from Xianyu (闲鱼), which is the second biggest retail platform of Alibaba Group, created an app using Flutter. It was downloaded more than 50 million times and has over 10 million active users every day. Choosing Flutter helped to save time because, with a single codebase, they could easily create and maintain the app.
Alibaba already had a pre-made app. That’s why their work began with implementing Flutter features step by step, adding more functionalities based on that framework to it. You can read more about Flutter and how it’s used in the Alibaba Group on their blog.
Groupon app is built with Flutter
Groupon is another example of a company that used a pre-made application. It had two types of apps – customer-facing and merchant-facing. The first now has more than 50 million downloads. The second one was much smaller, downloaded over 500 thousand times, that’s why it wasn’t so risky to implement new technology into it.
Groupon decided to integrate Flutter with an existing solution instead of rewriting the app from scratch.
One of the products from the major retail platform is built using Flutter. This mobile app allows users to sell and buy vehicles with their smartphones. With just a few taps, they can browse the offers, post advertisements and bid for the cars they like.
The main challenge that the eBay engineering team had to face was limited time – they had only one year to hit the market. They also wanted an impressive user experience that would include all the features known by eBay users. They stumbled upon Flutter that was in its 1.0 version and thought that it perfectly suits their goal. The main advantages included almost none platform-specific code, fast programming and awesome UI. They described the whole process – from discovering Flutter to finishing the app in their blog post: eBay Motors: Accelerating With Flutter.
One of China’s biggest enterprises that operates internationally and offers digital products and services also uses Flutter – and not for one but several of their applications. That includes DingDang, AITeacher, K12, QiDian, Mr. Translator and Now Live.
The main goal for Tencent was to create a smooth and beautiful experience for all their users, no matter which product they will be connecting with. Their applications are genuinely universal – they help with work, studying, traveling and many other daily activities. Hitting multiple platforms allowed Tencent to be flexible and highly available with their software. Developers used all the benefits of Flutter wisely – to code faster, integrate better and achieve spectacular results. They talk about all their processes in a YouTube video made together with Flutter.
Hamilton Musical Flutter app
GoPosse had a quest to develop a mobile app for Hamilton Broadway Musical. It was supposed to work on Android as well as on iOS. The team picked the Flutter framework because, according to them, it was faster and more fun to work with.
“Flutter made it possible to deliver more and at a higher level of quality. If we had developed two independent fully native apps, we never would have shipped the feature set we had at launch. The ability to do more continues to be a major benefit as we grow and add features to the app on a weekly basis.” ~ they stated in a blog post on the Posse Medium account.
Philips Hue Flutter apps
Philips Hue is a smart-home lighting system. They sell lamps, bulbs, accessories and starter kits for customers who want intelligent lights in their homes. Two of their apps are built using Flutter – Hue Sync and Hue Bluetooth. Thanks to these mobile controllers, Philips’ clients can change the tone of the light and synchronize lamps with their media kits.
Philips has used Flutter since 2018 and picked this technology even though other great solutions were available on the market. With Flutter, it just clicked and they knew it’s a perfect match for their project.
