Why Choose Flutter For Mobile App Development?

Flutter is a free and open-source mobile UI framework developed by Google that was introduced in May 2017. The official version was released in December 2018. Dart is a client-side programming language introduced by Google in 2009 and is the foundation upon which Flutter is built. Since its release, Flutter has gained recognition and is now incredibly popular amongst developers for mobile app development. As far as numbers are concerned, more than 400,000 apps have been built using flutter, and hundreds of millions of devices are running these mobile applications. If you are looking for a skilled developer for your business, you have landed on the right page.

It is widely used to build multiplatform and natively compiled applications extending cross-platform development support for Windows, macOS, Linux, and Web development from a single codebase. However, the most exciting thing about Flutter is that it is neither a framework nor a library. Instead, it’s a complete Software Development Kit (SDK). As a complete software development kit (SDK), Flutter contains a rendering engine, pre-built ready-to-use widgets, integration and testing APIs etc.

Benefits of a Software Development Kit over libraries and frameworks:

Broadly speaking, a library is simply a piece of code that is reusable and that developers use in an application to perform a specific standard function that helps them in mobile app development.

A framework provides the developer with a basic architecture and is a skeleton for building software and developing applications. Therefore, it can be considered a collection of tools that help the developer and serves as a foundation for development wherein the developer must add his code to fill in the blanks required by the application’s functionality.

An SDK offers a massive range of tools, such as APIs, libraries, frameworks, proper documentation and more, making it a more comprehensive resource for mobile app development and Flutter, which comes pre-packaged with all the tools needed to create cross-platform mobile apps.

Architectural layers of Flutter:

The Embedder offers the ability to execute a programme on any operating system through a platform-specific language.

An Engine written in the powerful C/C++ language provides a low-level implementation of Flutter’s core APIs. There is also support for text layout, network I/O, graphics, accessibility features, plugin architecture, and a Dart runtime and compilation toolchain.

A Framework is based on the Dart programming language. It provides a rich set of libraries that can be further classified into layers. These are the basic foundation classes, the rendering layer, the widget layer, and Material/Cupertino libraries.

Benefits of Mobile Application Development with Flutter

Flutter is the result of a group of mobile application developers at Google who sought to make their jobs productive and more efficient. These developers questioned the use of existing frameworks and developed a modern solution that included a new set of tools, a redesigned layout, and a faster rendering engine. Being a brainchild of Google, developers are likely to have faith in its robustness and have no reservations regarding its excellent functionality. However, the Flutter team’s main objective is to completely eliminate the cross-platform mobile app development challenges that every app developer has ever experienced.

Features of Dart and its Integration with Flutter

The Dart language, which aims to displace JavaScript as the default scripting language for web browsers, is entirely compatible with Flutter. In addition, Dart’s Hot Reload function is one of its main strengths, allowing developers to see changes they make instantaneously and runs efficiently across all platforms.

Developers benefit immensely from the Hot Reload feature because it can save them a significant time when developing new mobile and web apps. In addition, Dart’s Hot Reload functionality can cut the build time for big native applications to effectively zero.

Its syntax is comparatively easy compared to other well-known languages like Kotlin, Swift or TypeScript. As a bonus, Dart is the foundation for the open-source project Fuchsia, which aims to build a production-ready environment. Fuchsia is a work-in-progress framework with a vibrant community of contributors, and there are many exciting new features in the works which will further enhance the experience of mobile application developers.

Dart’s code is interoperable with all modern web browsers. Therefore, browsers do not need any kind of integration to embrace Dart. Furthermore, Dart comes with a large number of pre-built libraries and also employs the Ahead of Time (AOT) and Just in Time (JIT) compilers, which makes it faster and more effective. Talking about speed, it has been witnessed by many developers that Dart can sometimes outperform JavaScript.

Easy Deployment and Maintenance for Developers

Flutter is a framework with a single codebase, which implies that the same code may be used in mobile app and web development projects. Another aspect that distinguishes flutter is its custom widgets, which make prototyping much more accessible.

Flutter offers a discrete hot load feature that allows developers to tweak the application code and see the modifications fully effect in real-time without needing to reboot. This has made attempting new things more accessible and practical for developers, saving them time and sanity.

Because there is just one code in Flutter for all platform application upgrades, they can be released concurrently. This also makes it easier to maintain the application because there aren’t several developers working on it.

Flutter makes bug fixes and app maintenance super easy. Developers may even accomplish it in-house without the assistance of the development team or have only one developer do the modifications which makes it very cost-effective for any business as it requires less manpower.

Intuitive and Developer-Friendly UI

Aesthetic development applications are popular among developers. Therefore, the idea behind creating the UI is geared toward making the graphical user interface as appealing as possible to encourage developers to use it for longer and more consistently.

Flutter is more than just a simple framework with user-interface components like sliders, buttons, etc. It is a full-fledged software development kit with everything that any developer requires for high-quality mobile app development.

Flutter contains a range of discrete and appealing pre-built widgets, which ease the development process for developers ensuring they have little trouble working with them. In addition, the Flutter team is constantly improving the libraries providing users components to make applications more appealing.

Flutter’s Rendering Engine

Flutter’s UI rendering is pixel-perfect. Flutter does this through its engine, which is in charge of translating the code into what is displayed on the device’s screen. Flutter app development for any platform has a rendering engine that handles graphics at runtime.

This also illustrates how Flutter is cross-platform and efficient in terms of user-interface rendering. However, this is primarily about the engine’s efficiency. Flutter uses the Skia graphic engine, a 2D graphics library and manages the rasterisation of visuals on various hardware and software.

Skia is not the only component of the Flutter rendering engine. It also provides minimal implementations of Flutter’s fundamental APIs (such as text and network I/O).

The Flutter engine is sufficiently strong that it can re-render user interfaces at 60 frames per second. As a result, whether there are UI updates or animations, the machine does them as quickly as if it were a native programme.

Flutter is Scalable

The Google Firebase application powers flutter at its backend. It assures quick data synchronisation and enables real-time database change. As a result, the number of updates needed for synchronising was minimised. Flutter enables developers to add functionality to the app or grow the user base in the future while maintaining excellent performance. This capability allows enterprises to extend their apps effortlessly.

Device Adaptability

While existing smartphones have a variety of screen dimensions and different aspect ratios, upcoming modern gadgets with flip displays and folding screens are being introduced, which makes it difficult for developers to create an app that will work on all of these different screen sizes. However, with flutter, this is likely very simple. In addition, they feature a layout framework that allows the developer to fit the application into any screen size.

Flutter offers an ambient computing experience bringing the idea of apps that can be available anywhere without device limitations to reality.

Reusable Widgets

Widgets such as menus, fonts, colours, buttons and more may be combined to build complicated or customised applications. Gadgets help developers to build apps without having to write code from scratch and thus results in saving their time while increasing productivity. For example, Flutter has a plethora of ready-to-use widgets that enables developers to create various designs that adhere to the best standards. Developers can never go wrong when using these pre-designed widgets.

Flutter is future-ready with support for Fuschia

Fuschia is the most talked-about new operating system amongst techies that Google is actively working on and is set to replace Android in the coming years. Flutter App Development will be easier as it will be interoperable with Fuschia, so it is indeed future-ready, while other native apps will still be pondering the changes. Despite the lack of information, developers may not be concerned about this modification when using Flutter.

Cost Effective for Businesses

Flutter enables the creation of both the iOS and Android operating systems from a single codebase, drastically reducing the time required to produce separate applications. As a result, businesses do not need to hire additional developers to build code for applications compatible with multiple operating systems. Instead, they save time and money by hiring reputable and dedicated Flutter mobile app developers. This even gives businesses the flexibility to create an MVP (Minimum Viable Product) to try and test on the audience before committing to a full-fledged native or cross-platform software.

Wrapping Up

Flutter has made it possible to replace traditional architecture, and it is no secret that Flutter has gained a lot of traction in the developer community lately. Flutter’s ability to support six distinct platforms with a single codebase is a significant factor in the project’s overall success.

With the pre-built and ready-to-use widgets, state management capabilities, and much simplified debugging tools, Flutter makes it easier for developers to get the apps up and running in no time. It is also backed by a large community of developers and industry leaders for support in favour of the simpler Dart.

Google dropped the idea of using JavaScript due to its complexities and inconvenient nature. However, the organisation successfully met this goal, making the framework convenient for developers and advantageous to entrepreneurs. The technology undoubtedly saves time, money and human resources while offering almost native productivity of an application.
