Why is Flutter a Good Choice for Cross-Platform App Development?


In today’s fast-paced digital world, businesses and developers are constantly seeking efficient ways to deliver high-quality applications across multiple platforms. Cross-platform app development has emerged as a popular solution, enabling developers to build mobile applications that run seamlessly on different operating systems like Android and iOS. Flutter, an open-source UI framework created by Google, has gained significant attention and acclaim as an excellent choice for cross-platform app development.

In this blog post, we will explore the reasons why Flutter is a good choice for developing cross-platform apps.

What is Flutter?

Flutter is an open-source UI software development kit created by Google. It is used to develop cross-platform mobile applications that run on Android and iOS devices from a single codebase. First described in 2015, Flutter was released in May 2017.

Benefits of the Flutter Framework for Mobile App Developers:

Easy to Learn

Flutter is built using Dart, Google’s own programming language released in 2011. While Dart’s adoption at Google has been extensive with Google Fibre and Adwords teams, using it to write their customer facing web apps, externally its adoption has been a bit slow. However, this is likely to change soon with Flutter.


Well, for starters, Dart has many Object-Oriented features that the typical JavaScript programmers might be unfamiliar with, but they’re essential for serious development. Secondly, according to Dru Keppel, Dart is Google’s replacement for JavaScript. In simple terms, Google feels that JavaScript cannot stretch itself more to the stature of being called a modern programming language, which Dart is, and that gap is what Google aims to fill.

Reduces Development Time

Uptil now, Android app developers as well as iOS app developers had to push each set of changes on a device to test them, which really added a lot to the total app development time. But with Flutter’s new “Hot Reload” feature, developers will be able to see the results of the changes in fraction of seconds, eliminating the waiting time to deploy and test an app on a device.


Well, the Hot Reload works by injecting the updated source code files into the running Dart Virtual Machine. And once the Dart Virtual Machine updates classes with the new versions of functions & fields, the Flutter framework automatically rebuilds the widget tree, allowing developers to quickly the view the results of changes.

In a nutshell, Flutter’s hot reload will multiply the productivity, cut down cost, and reduce app development time.

Widgets for Everything

If you know the basics of mobile application development, then you might be familiar with Widgets – they’re critical for app’s view and interface. Furthermore, they need to look interactive and natural, despite the different screen sizes. In addition, they also must be customizable, extensible, and should be able to perform fast.

Guess what?

Flutter makes it all these possible with its own widgets. That’s right! Flutter’s widgets incorporate all critical platform differences such as scrolling, navigation, icons and fonts to provide full native performance on both iOS and Android. Dig deeper, and you’ll find that each widget is made of smaller widgets. Those widgets are further bifurcated into smaller widgets. Programming with widgets in Flutter would ultimately boost productivity.

Unified App Development

When developing a mobile application, native development usually costs more for both, coding as well as ongoing support. Plus, you’ll spend that amount of money twice, considering the fact that sooner or later, you will be targeting both Android & iOS platform.

What’s More!

We all know that the process is tedious, time-consuming, and extremely costly. But with Flutter, you’ll be building ‘a mobile app’, and not an Android app or iOS app, which means you build just once, and use the single codebase for both platforms. Voila! With Flutter, you’ll be building ‘a mobile app’, and not an Android or iOS app. This way, your mobile app development team will only have to write the UI and navigation just once, and simply share it across Android and iOS. In simple terms, it offers a great opportunity to ‘write once and deploy everywhere’.

Bottom Line is…

In the ever-evolving landscape of cross-platform app development, Flutter stands out as an exceptional choice. With its ability to create apps with a single codebase for multiple platforms, its fast development cycles, and its beautiful UI capabilities, Flutter offers a highly efficient and cost-effective solution. The framework’s high-performance rendering engine and strong community support further solidify its position as a top choice for mobile app developers.

As businesses seek to leverage the benefits of cross-platform app development, partnering with a Flutter app development company can unlock the full potential of this powerful framework and ensure the delivery of exceptional and successful applications.
