What is Flutter Framework?

You are probably already using applications made with the Flutter framework. Be it a Google ad you see on a website, a payment you make through Google Pay, or shop on Alibaba, you have come under the Flutter radar.

After its launch in 2018, it took only a few months to gain popularity. It is basically an open-source technology introduced by Google to create dynamic web, mobile, and desktop apps.

Since Flutter is an SDK, it includes testing APIs, rendering engine, ready-made widgets, integration APIs, and many more. Dart is the name of the Flutter programming language that forms the foundation of this technology. It is object-oriented and client-optimized, and the best part is it has the potential to compile native code without any additional bridge to interact, for instance, React Native.

Another fantastic part of Flutter app development is the widgets that serve as the building blocks and cover almost all aspects of development. The tool also automates the whole unit, widget, and integration testing process.

Take a look at the skyrocketed popularity of Flutter that has set it apart from the rest of the app development frameworks:

Why Do Developers Choose Flutter as Their Mobile App Development Framework?

You might be wondering what's so unique and innovative about Flutter? Every cross-platform app development framework has some out-of-the-box features to offer you, and you are absolutely right about that.

However, Flutter does not play by the same rules and is many steps ahead of the existing development tools. Let's walk through the biggest reasons why you should opt for mobile app development using Flutter:

Dart as the Programming Language

Dart is the official Flutter language that promotes dynamic design and powerful architecture. Using cutting-edge compilation tools, Dart offers faster load times, quick execution of codes, and a lightning-fast development cycle, which other currently available mobile programming languages cannot do.

Enhanced Development Process

Since Flutter works on rendering libraries, graphics, and native binaries based on C or C++, creating high-performance and futuristic flutter app is way simpler for an app developer. Additionally, since apps made with Flutter can reach up to 120fps on compatible devices and improve the efficiency of digital products, it has become the best framework for app development.

Skia as the Rendering Engine

To provide the best user experience, Flutter provides variations within the application. Skia, being Flutter’s rendering machine, makes it a lot simpler to install Flutter on Windows, Mac, Android, or any other virtual platform or device.

The reason behind using an individual rendering machine is to allow developers to use the same UI codebase for any platform without the need to adjust or recreate it.

Superior Accessibility

Flutter is the best framework to develop mobile apps for startups. With a range of tools for efficient development. Flutter comes with application APIs, third-party integration, and local codes to simplify the application development life cycle.

Reduced Development Time

The Flutter team has put in a lot of effort to make it the best app development framework by providing a wide variety of fully operated and ready-made widgets that enable customizing the app as per your unique business requirement. It also lowers the risk of writing codes for each functionality or widget from scratch.

This not only saves time but also saves the effort of the developers. With the improvement in the accessibility of these tools, any developer can customize the software with complex app architecture patterns through a smooth development experience.

Platform Benefits of Flutter Mobile App Development

The ability to customize anything and everything on Flutter is what we can understand in the big picture. But, regardless of the obvious ones, there are many more possible advantages of this progressive mobile app development framework

It comes with cross-platform compatibility

Flutter is the best framework for mobile apps because of its SDK that allows developers to share both the UI and the UI code on multiple platforms. As a result, developers can build an application that works and looks like a native app on every platform.

It takes less time to code

As mentioned earlier, since it is single code-based and cross-platform, it reduces the time of development. For example, you can ship a mid-size Android app in just 40 seconds to a test device.

It is easy to use

Flutter is one of the easiest development frameworks. It functions way quicker than all its alternatives, and developers do not need to write any platform-oriented code for this SDK.

It is fully customizable

One of the biggest advantage of Flutter is its rich SDK and API, which enables developers to create custom UI elements and access platform-specific features with ease. What can be better than that? Though the part of customization is offered by many other frameworks as well, with Flutter the reduced amount of effort is head over heels satisfactory.

Why is Flutter the Best Mobile App Development Framework for You?

For you to have clarity, here’s an overview of the Flutter architecture and how the characteristics of this tool have gained the limelight as the best framework for mobile app development.

Native Approach to Stay Relevant

Applications built with Flutter have a completely native look and feel without compromising performance. The preconfigured widgets can incorporate all the critical platform differences like scrolling, navigation, icons, and fonts.

Apart from that, Flutter also offers brand customization, where you can modify the widgets based on your target audience and brand preference. Moreover, if you want your mobile apps to target end users of a specific geographic location or a common cultural background, the internationalized libraries empower Flutter mobile developers to build and modify the UIs of the application based on the preferred language, text, and layout.

Hot Reloads for Instant Updates

Flutter for app development offers a virtual DOM that helps you store widget trees and apply changes only to the relative code in the tree. But, unlike other frameworks, Flutter has taken it a step further by introducing Ahead of Time (AOT) which gives developers the chance to review changes instantly.

The AOT compiler of Flutter has managed to convert everything into a widget. Other reactive platforms have to use a JavaScript bridge to pass information from the application to the platform. But Flutter has its own widget platform, so there is no need for the JavaScript Bridge. This makes Flutter a perfect choice for mobile app development for your business.

Apart from that, when developers choose Flutter for app development, they don’t have to use multiple platforms for managing their applications. Developers can use Flutter itself to develop, deploy and render changes to the application. They can also use it to allow other non-technical users to contribute and supervise the development, making it a one-stop solution.

Complete Customization and Reusability

Flutter allows third-party development vendors and individual developers to build and customize their own widgets and make them available in the market. Thus, even in the future, if Google shifts its attention from the platform, the development company undertaking Flutter app development can create and customize their own widgets.

In other words, not only do you get access to standard UI widgets that has a high user acceptance probability, you get to build your own customized widgets and the best Flutter apps that are completely brand or industry-focused.

Constant Upgradation and Developer Community

Flutter is not only dominating the current mobile app development market, but it also seems that the Flutter team from Google is planning to retain its position in the market. The agenda is simple, “If you can’t innovate, your product will suffocate in the competition!”

Google understands this really well and is vigorously working on updating its platform. For instance, recently, Flutter 3.19 - the latest version of this framework - was released with a range of enhanced features and functionalities.

Cost-Effectiveness at Its Best

The Flutter app development cost is another reason why it's the best framework to develop mobile apps. The framework's benefits to development teams and enterprises outweigh its drawbacks by a wide margin. Flutter is a great option for startups, no matter where they are in the world, to build an MVP and, subsequently, a feature-rich app.

For instance, Flutter reduces the app maintenance cost by 20% while cutting the app development cost by practically half.
