Have you ever played with LEGO or any other block-building games?
Such games give oneself an opportunity to play without structure, to build and take apart as necessary. And when the blocks are a bit more sophisticated, as LEGO is, a broader range of things can be built.
Google wants developers to start off with the question – “What am I going to build today?” without having to worry about “What device do I want to target?”
Things About Flutter That Will Interest You
Flutter will help Google achieve what it calls Ambient Computing – the idea of building digital, online, native apps completely free of device limitations, thereby making app development cost effective.
So no matter where you want to run your apps – mobiles, laptops, tablets, wearables, TVs, and smart displays – Flutter will automatically optimize the code for you.
The UI toolkit uses the programming language of Dart. Flutter chose Dart as their preferred language to support its two critical features:
- A JIT-based fast development cycle that allows for shape-changing and stateful hot reloads without needing a full recompile
- Ahead-of-Time compiler that emits efficient ARM code for fast startup and predictable performance.
Further, Material (for Android) Design and Cupertino (iOS-styled) widgets are incorporated into comprehensive sets of controls for enhanced app UI. It not only looks and feels native but can also imitate the platform itself to behave naturally on any platform, even though you’re using the same codebase.
Below is the architectural layer diagram of Flutter.

Flutter vs its Competitors: in a brief
Google has developed Flutter as an open-source UI framework that is designed to compete with the likes of Facebook’s React Native, Microsoft’s Xamarin.
What is Xamarin? Xamarin is an open-source, cross-platform application builder that uses .NET and C#. The robust platform is widely-used in an enterprise setting. Off late, it is only used to build web apps.
Some developers say that React Native components are pretty basic while Flutter offers a more comprehensive suite of widgets. Flutter even boasts more libraries and fewer native calls to the bridge.
1. Community & Support
- Open-source platforms rely on the popularity of their user community and their contributions to the platform.
- React Native has been around for more time than Flutter. It is powering thousands of applications around the globe including Instagram, Shopify, and Walmart.
- The size of the technology community is still modest in size, however, Google’s support to the platform cannot be overseen. There’s a distinct upward trend in the number of Flutter supporters who are willing to adopt it for cost effective application development.
2. Code reusability
- It is easy to build a mobile or web application – the challenge lies in delivering it within the agreed time and budget.
- Using React Native, code can be reused across platforms but requires rewriting a number of sections like styling elements and finer nuances. Moreover, about 70% of the code used in a web app can be reused in the corresponding mobile app using React Native.
- However, with Flutter, native digital app development becomes extremely efficient thanks to hot reloading, predefined widgets, and pre-built tooling. Flutter proposes to offer a single integrated code for mobile, web, and desktop. Allows developers to easily rewrite sections of code that need to be customized to the platform.
3. Project Documentation
- The popular app stores like Apple App Store & Google Play Store follow strict documentation guidelines before any application could be listed on it. Comprehensive, user-friendly documentation support can make developers’ lives a whole lot easier.
- The official React Native provides insufficient support on the automated deployment of iOS apps into the App Store and offers no help with CI/CD best practices.
- Flutter seems to be much better in this regard. The framework provides rich, well-structured, and detailed documentation for setup, testing, and deployment, to simplify the developer’s job and speed up the delivery of mobile apps.
- A detailed performance review, CPU/Memory usage of Flutter and React Native are conducted, and the results of the same are analyzed in this article.
Why Choose Flutter For App Development?
Split-second compiling for instant preview: The hot-reload functionality of Flutter enables developers to instantly look at the changes made to the code and adjust accordingly.
Access to original source code: Flutter has preferred an open-source framework, with a permissive BSD license. Thanks to the thriving ecosystem of third-party packages, it supplements the core library functionality, ie., the ability to alter the original source code to suit your requirement. (remember, widgets are the building blocks of flutter which makes it easy to code and create graphically intuitive apps)
For example, you can access the code for a predetermined button widget, ie., floatingactionbutton(). You can customize its shape, color, elevation for visual appearance, which otherwise would be impossible with iOS native app builders.
Flirting with Flutter - Building Popular Apps!
1. The New York Times
Flutter is not just popular for building mobile applications but is equally powerful for building web-based applications. The best example for this is The New York Times, and they are doing it on their crossword puzzle app – KenKen.
The New York Times is famous for its crossword and other puzzle games. Since avid puzzlers want to play on whatever device they’re using at the time, their development team was attracted to Flutter as a potential solution for their needs. Discovering that they could reach the web with the same code was a huge boon.
Rather than rewriting code for their puzzle app for every different platform, they can just write it once with Flutter.
Eric von Coelln, Executive Director of Puzzles at the New York Times has to say about their experiences with Flutter:
“The New York Times Crossword has more than 400,000 stand-alone subscriptions and is a daily ritual for puzzle solvers. Along with the Crossword, we’ve grown our portfolio of digital puzzles that reach more than two million solvers each month.
We were already beginning to explore Flutter as a potential solution to the challenge of quickly developing engaging, high-quality mobile experiences. Now the addition of being able to publish to the web makes Flutter an even more appealing option to quickly deploy across all of our user platforms. This update of our old Flash-based KenKen game into a multi-platform playable experience is something we’re excited to bring to our solvers this year.”
Reflectly is a Health monitoring app that was essentially built using React Native. However, the makers did not enjoy its Android version and decided to make a switch.
They found Flutter as a convenient platform. They “fell in love with the cross-platform consistency, near-instant stateful hot reloading, great tooling and high performance of the platform”.
The complete experience of Reflectly in shifting from React Native to Flutter is detailed here.
One of the world’s biggest e-commerce platforms decided to go in with Flutter for their mobile app development. They wanted an app that delivered beautiful graphics yet loaded fast. Flutter’s fast Frame Per Second (FPS) and sharp UI and navigation are some of the best things they needed.

4. Philips Hue
Philips is the leading smart lighting solution. Its smart mobile application- Philips Hue is designed to let users control and create vibrant automated lighting solutions from the app itself.
Flutter’s platform helped them deliver an app with intuitive controls, one that would provide real-time sync for the smart lights to the media hub.
There are other popular applications such as Google Adwords, Google Fiber that are built using Flutter. Further, Flutter’s vibrant Developer Community is now 150,000+ strong and active on GitHub, google groups, stack overflow, discord, medium, and more.
There are very specific use cases where you may not want to use Flutter though.
- If you are for some reason completely devoted to having a native app, you’ll go through native app development.
- If you require an app with 3D touch, Flutter does not support that as of now.
Flutter’s package ecosystem supports a wide variety of hardware (such as camera, GPS, network, and storage) and services (such as payments, cloud storage, authentication, and ads). However, if your app requires heavy interaction with device hardware such as the camera or phone call, you may find Flutter just a little bit lacking.
- Flutter apps tend to be heavier in terms of application size so if you want a particularly small app, you may want to skip over
The multiple benefits offered by Flutter overshadow the few shortcomings. Google’s backing makes it an even stronger candidate to dominate cross-platform native digital, online app development.
Google is regularly releasing new updates, adding widgets and libraries to extend app features in the stable and beta channels of the Flutter framework.

Here’s what Larry McKenzie, a senior developer at eBay had to say about Flutter:
“Flutter is fast! Features that once took us multiple days to implement can be finished in a single day. Many problems we used to spend a lot of time on, simply no longer occur. Our team can now focus on creating more polished user experiences and delivering functionality. Flutter is enabling us to exceed expectations!”
Summarising: When to Use Flutter
Since its launch in 2017, Flutter has not only gained immense popularity among developers, but it’s also catching on with businesses/marketers. As a developer, you save weeks of writing platform-specific code. As a business owner, you save time and money and get your product to market sooner.
Win-win in any case!
Even as Google is perfecting its new open-source operating system- Fuchsia OS, Flutter is on the right track to becoming the next big thing in native and hybrid app development.
- Highly recommended by the creators of Flutter for the delivery of 2D cross-platform apps.
- This is to suggest that it works best with brand-first designs.
- Wherever aesthetic design and seamless UX are the priority, Flutter offers the best results in building an intuitive UI on your application.
- Best suited for projects impacted by a tight budget and time constraints.
- The technology creates a good match for mobile apps focusing on e-commerce, healthcare, lifestyle, and banking, and finances.
