Why Flutter is the Most Popular Cross-Platform Mobile SDK


Our mobile gadgets and applications are crucial to our lives. There are currently over six billion smartphone subscribers worldwide. Furthermore, there are nearly five million mobile applications accessible for download across the Google Play Store and the Apple App Store. Despite the fact that the mobile application market is becoming increasingly competitive, many companies and developers are concentrating their efforts here.


As a result, it’s only natural for mobile app developers to explore for easier, faster, and less expensive ways to get their products to market. In this process, effective development tools are critical. The tools that developers employ, from programming languages to app frameworks to software development kits, impact how quickly they can get a product in front of customers.


Let’s look at Flutter’s meteoric growth in popularity and the qualities that make it so appealing to programmers. Hire Flutter Developer


What Exactly is Flutter?

Flutter is a free, open-source software development kit (SDK) from Google for creating cross-platform mobile apps. Flutter allows developers to create high-performance, scalable Android or iOS apps with appealing and functional user interfaces using a single platform-agnostic framework. Flutter is based on a collection of ready-to-use widgets that allow even those with little programming or development skills to swiftly launch their own mobile apps.


Flutter was created by Google in 2015 and released in 2018, and it has swiftly become the toolkit of choice for developers. Flutter has now eclipsed React Native to become the most popular mobile app development framework, according to Statista.


How does Flutter Function?

The framework, engine, and platform-specific embedders make up Flutter, which is a layered system. Google’s Dart object-oriented programming language is used to create Flutter apps. The Flutter engine is mostly written in C/C++. Flutter’s graphics capabilities are built on the Skia library.


Many of Flutter’s performance advantages are built on Dart. It can compile ahead-of-time (AOT) as well as just-in-time (JIT). AOT compiles code into native code at a lower level, resulting in apps that start up faster and perform better. Flutter’s hot reload capabilities (described in greater detail below) is made possible by JIT, which decreases development time. Dart now compiles to native ARM or Intel x64 code, reducing the speed gap between Flutter apps and native programmes that rely on runtime intermediate code interpretations.


Flutter’s architecture also allows adding features or accommodating new users straightforward and rapid, making it highly expandable and scalable.


Why is Flutter so Popular Among Mobile App Developers?

Flutter’s popularity is on the rise, and with good reason. Flutter provides a slew of advantages to developers that speed up development and result in more user-friendly mobile apps.


Flutter is Platform-Independent

Any developer planning to release a mobile app understands the importance of having versions for both Android and iOS. With a 72 percent market share as of September 2021, Android has a tight grip on the mobile market. However, with nearly a 27 percent market share, iOS has a sizable user base.


Focusing on a single native application misses a significant portion of the market and limits the app’s potential future success. Separate native programmes, on the other hand, might be time-consuming and expensive to develop.


Flutter makes developing for multiple platforms a breeze. Rather than writing code for each platform separately, developers can use Flutter’s one codebase.


However, Flutter’s cross-platform adaptability extends beyond code portability. Flutter-built user interfaces (UI) are also platform-agnostic, unlike other cross-platform frameworks like React Native and Xamarin, because Flutter’s Skia rendering engine does not require any platform-specific UI components.


Flutter makes Application Development Easier and Faster

Flutter includes a number of capabilities that enable developing cross-platform mobile apps easier and faster. The ability to use a single codebase and UI engine for cross-platform development, for example, decreases the time and work required to create versions of an app for Android and iOS.


Flutter’s vast widget library also provides developers with ready-to-use functionality, which cuts down on overall coding effort. Reduced coding time also means lower development costs.


Flutter’s stateful hot reload functionality is one of the most crucial aspects for saving development time. The use of JIT compilation in hot reload speeds up the implementation of code modifications. Flutter uses hot reload to insert code changes into a running Dart VM while preserving conserved states. Because the app code is not completely recompiled, the consequences of code updates are displayed more immediately when using hot reload. Hot reloading allows developers to see the impact of changes in real time without having to change the application’s current state. As a result, developers can test new features and versions more quickly, as well as repair errors. As a result, both original applications and updates require less time to reach the market. As a result, Flutter is ideal for creating and launching MVP applications.


Flutter is a fantastic solution for companies with low funds due to its efficiency. For example, a startup may have already spent at least $75 per hour on a web designer and may expect application developers to spend similarly or more. Flutter is a cost-effective development platform for organisations who want to reduce development time and get products to market faster.


Flutter is Simple to Learn and Use

Flutter is straightforward to learn, even if you don’t have a lot of programming experience. Developers that frequently deal with other object-oriented languages, such as Java, Python, C#, or others, will find Flutter and Dart to be a natural fit, as Dart is structurally and syntactically similar to those languages. Furthermore, for people with less programming experience, Flutter’s rich widget library makes it simple to create apps without writing a lot of code; some platforms use Flutter to create apps without writing any code!


Flutter also comes with a wealth of documentation. The Flutter support materials include multiple example apps, a “cookbook” instructing developers how to execute typical tasks, and even a recommendation for a Flutter training camp, in addition to the general reference handbook.


However, Flutter’s widespread acceptance has resulted in a lively community that offers support and resources to new and seasoned Flutter developers. Developers can get advice and information from a variety of blogs, forums, and other online groups, such as:


The Flutter wiki and question pages on Stack Overflow

Flutter Awesome is a one-stop shop for all things Flutter, with tutorials, libraries, UIs, apps, and more.

The flutter-dev Google Group is a great place for developers to get help with technical concerns.

The official Reddit Flutter community’s flutter-dev subreddit, where participants share resources and expertise.

These are only a few of the materials available. Many more can be found with a fast search.


Flutter is a Good Scale to Use

Developers must be able to easily add functionality to an application or expand its user base without breaking it. On the backend, Flutter relies on Google’s Firebase application, which was designed with scalability in mind. Firebase provides real-time database changes, ensuring that data is synced between clients promptly. Firebase additionally optimises and reduces the number of changes required for syncing, so adding new users of functionality has no detrimental influence on performance.


Flutter Apps Provide a Fantastic User Experience

Mobile apps must have well-designed, beautiful, and functional user interfaces in order to be genuinely successful. Flutter, on the other hand, specialises at creating a fantastic user experience.


The built-in widget catalogue in Flutter is dedicated to provide high-performance, visually appealing application pieces. Flutter makes creating UIs with numerous components, from the most basic to the most complex, almost trivial.


There are no intermediate code interpretation processes in Flutter apps because they are compiled directly into native code. Flutter eliminates additional processing steps that slow down speed, making it substantially faster than competing cross-platform development apps like React Native, which require bridges between their code and native parts.


What are the Drawbacks of Utilising Flutter?

Flutter, like any other SDK, isn’t flawless. While its advantages outweigh its drawbacks, aspiring Flutter developers should be aware of its restrictions.


Apps that are Large

Many developers are concerned about the size of their applications. Despite the fact that most mobile devices have plenty of storage, a device can quickly fill up with images, movies, and graphics-intensive games. The problem gets worse as the equipment gets older.


Instead of relying on platform aspects, Flutter apps are self-contained and contain all of the necessary code to execute the app, resulting in bigger app sizes than traditional applications. The scale of Flutter applications may be an issue for developers wanting to appeal to a wide spectrum of potential customers, leading some to select a different language.


There aren’t any Third-Party Libraries Available

Third-party libraries aid in the reduction of development time and expenses, and many developers rely significantly on them. The built-in widget library in Flutter is large, and the official Flutter package site has thousands more alternatives. However, because Flutter is still a young programming tool, third-party libraries have fewer resources than other development tools. However, as more people switch to Flutter, the third-party Flutter ecosystem is fast expanding, and you should expect this issue to decrease over time.


Platforms are Limited

The number of platforms on which Flutter applications can run is currently limited. Flutter, for example, cannot be used to create applications for watchOS, tvOS, or Apple CarPlay. This is a crucial constraint, as overall wristwatch sales are estimated to exceed a quarter of a billion units in the next five years. Flutter tries to solve this problem by giving workarounds like adding native Apple Watch extensions to Flutter apps.


You Must Learn Dart

You must be familiar with Google’s Dart programming language in order to use Flutter. While Dart is not difficult to learn for object-oriented programmers, it is less well-known and used than other object-oriented languages like C#, Java, and JavaScript. As a result, developers that want to go to market fast may choose to avoid Flutter due to the increased learning curve.


It May be More Suitable for Android than for iOS

It’s not unexpected that Flutter’s functionality on Android is superior to that on iOS. As Flutter fixes and updates hit the market, there are already cases of iOS functionality lagging Android. After all, Google, Android’s most vocal supporter, is the driving force behind Flutter, and Android accounts for the great majority of the mobile market. Flutter is used by more Android developers than iOS developers because it is a Google product. There are also rumours that new Android features make their way into Flutter faster than new iOS features. As a result, iOS developers should keep an eye on future Flutter releases.


What does Flutter have in Store for the Future?

Flutter’s market share is beginning to plateau after a rapid growth in usage over the last three years. However, this should not be interpreted as an indication that Flutter will be phased out anytime soon. You can only presume that, given the tool’s present popularity, Google will attempt to remedy some of Flutter’s more serious flaws, such as application size, and that the lack of third-party resources will be addressed. Developers are likely to continue to utilise Flutter because of its simplicity and power. Hire Flutter App Developer


Will there be new and popular tools that try to take Flutter’s place? It’s almost certain. Flutter, on the other hand, has a bright future ahead of her.
