Flutter for cross-platform development

Undeniably, presently, life seems to be impossible without mobile applications. Worldwide, nearly five million apps are floating around the Google Play store and Apple Store, which users can download. The growing prominence of mobile apps has made the app market very competitive, which has made businesses rethink their mobile app development strategy.

Businesses are looking for a quick, simple, and easy way to get the app developed for multiple platforms in low-budget. That’s where, building the app for two different platforms android and iOS using one codebase, which is a cross-platform app development approach is gaining traction. Here the selection of the frameworks and other developmental tools for cross-platform development play a vital role in getting build a product that renders high performance and delivers the best user experience on all the platforms.

Flutter turned out as the best alternative that helps businesses shape the app idea into a full-fledged solution for multiple platforms using a common codebase without compromising on design, UX, performance, or any other factor. Top Flutter developers leverage pre-built widgets and UI components for attractive and functional app development that works seamlessly on various platforms.

Yet, if the popularity and growing usage of Flutter do not convince you to use the framework, a couple of more reasons are enlisted. Let’s understand in detail how a platform-agnostic framework- Flutter is the best choice for cross-platform app development.

7 Reasons to Choose Flutter for Cross-Platform Development Project

Flutter offers several advantages when leveraged for mobile app development for cross-platform devices or multiple mobile OS that we will discuss in this section extensively.

Flutter for Cross-Platform Development Project

Single Codebase for all Platforms

With Flutter, you write one codebase that can run on multiple platforms, including iOS, Android, web, and desktop. This means you don’t have to maintain separate codebases for each platform, thereby saving time, development cost, and effort. You can achieve up to 95% code reuse across platforms, which leads to faster development and easier maintenance.

In addition to mobile platforms, Flutter has expanded its support to desktop and web applications. With Flutter, you can build applications that run on Windows, macOS, Linux, and the web, further extending the reach of your codebase.

What’s more? when it comes to updating the cross-platform app with more features or UI redesign, updating the code once enables reflecting changes in all the apps without needing to concern about platform-specific coding.

Faster Development and Updations

Businesses look for a framework that helps them launch apps on various platforms in reduced time and low budget. Flutter’s hot reload feature speeds up the multi-platform mobile app development process by allowing cross-platform developers to make changes quickly without needing to restart the app or lose its current state.

Flutter injects the modified source code snippet into Dart virtual machine wherein Flutter rebuilds the widget tree and classes are updated with new fields and functions automatically. This way changes in code get updated and are viewed in real-time.

Hot reload enables rapid iteration, experimentation, and fine-tuning of the user interface, leading to faster development cycles and increased productivity. Thus saving your time and money.

Native-Like Performance

Flutter apps are compiled into native code, which enables them to achieve high performance. Taking a step ahead, The cross-platform framework facilitates User Interface and UI code sharing as there’s no need for platform-specific UI components for UI rendering.

Flutter’s architecture eliminates the need for JavaScript bridges or interpretation layers. Instead, it uses a high-performance rendering engine called Skia, which provides smooth animations, efficient UI rendering, and excellent performance on par with native applications. Thus, the usage of Flutter for your cross-platform helps you to connect with your mobile app users without spending extra budget on native app development.

Beautiful UI that Easily Adapts to Different Screen Sizes

As a top framework to build custom cross-platform applications, Flutter offers a rich set of customizable UI widgets, animation libraries, and extensive graphics enabling the creation of visually appealing and consistent user interfaces across different platforms.

It includes an extensive library of Material Design and Cupertino widgets, which follow the design guidelines of Android and iOS respectively. These widgets are highly customizable, which allows you to achieve pixel-perfect designs for your cross-platform apps that seamlessly adapt to various aspect ratios and screen sizes of different digital devices. Also, The support for 3D graphics allows the use of 3D tools for creating 3D meshes and models to build your cross-platform mobile app.

Access to Native Features

Businesses are increasingly opting for progressive web apps as an alternative to native apps, but not-up-to-the-par performance deters them. Unlike other cross-platform development frameworks, flutter excels in building high-performant PWAs as they are directly built into machine code and enable accessing native features.

Flutter is a cross-platform technology that provides a flexible bridge called “platform channels” that allow direct communication between Flutter and native code. This means any platform-specific features or APIs that are not yet available can be accessed and utilized through Flutter’s core framework. Flutter developers that you hire can leverage existing native code, access device sensors, use camera functionalities, and interact with third-party libraries seamlessly.


Flutter’s cross-platform capabilities can save significant costs compared to developing separate native applications for each platform. With a single codebase, you can reduce development efforts, testing efforts, and maintenance costs. Moreover, Flutter’s fast development cycles and hot reload feature contribute to faster time-to-market, which can be cost-effective for businesses.

Additionally, Flutter ensures that there will be no compromise on the cross-platform app’s quality, design, and performance when the apps are built for multiple platforms, it saves huge amount of money that need to be spent at a later stage to fix the issues.

It’s Open-Source that improves Accessibility

Flutter enables easy access to the cross-platform development project’s codebase that provides great insight into the development process. Flutter has a vibrant and rapidly growing developer community for cross-platform development. This means finding resources, libraries, and packages to help solve problems and speed up development can be done easily. Additionally, the cross-platform app development framework benefits from strong community support, including regular updates and improvements.

While reporting bugs for cross-platform app development, the active community developers provide the necessary assistance that your hired Flutter app developers can avail of for better results.
