How Does Flutter Work? Here’s How

Flutter, which Google released in May 2017, is widely recognized as one of the most useful, open, flexible, and expressive user interfaces available. It is a framework for developing apps for smartphones and other mobile devices that is quick and safe. Flutter offers useful services for developing fast apps and has proven to be a paradigm of open development.

In this article, you will get to know how Flutter works.

Flutter: Defined

In dealing with many apps on the devices, these questions may arise: What is Flutter? How does Flutter Work?

Essentially, Flutter is an excellent solution for developing apps for both Android and iOS. Many of these devices’ features get integrated using the Dart programming language. Developers can make proper use of a single code base for the compilation of multiple platforms.

What Makes Flutter Stand Out?

Flutter is a cross-platform development framework that combines the quality of native apps with the flexibility of cross-platform development.

Many cross-platform tools allow you to write code once and utilize it on both iOS and Android. However, not all can imitate the look of a native app. But that is what Flutter does: rather than being a wrapper on native UI components (like React Native and Xamarin are), Flutter creates the UI from the ground up.

Flutter keeps the app’s native look and feel; thus, you will not have to worry about its performance on any platform.

The Benefits of Flutter Apps

You must consider the following points to comprehend Flutter’s benefits and features better:

Simple and Quick

One of Flutter’s strongest advantages is how quickly and frequently it responds to changes. Changes in code on hardware, emulators, and simulators may be to blame for these changes. This modification can happen in a matter of seconds, and there is no need to restart it. This modification is successful in terms of issue correction and adds significantly to the rapid development of user interfaces.

Moreover, many programmers and non-programmers have contributed to the development of flutter apps. Such an advantage demonstrates how simple it is to use.

Highly Productive

Flutter is a cross-platform application. Thus, both Android and iOS apps can share the same base code. This adaption can help users save time.

Easy to Handle

Flutter is a user-friendly platform with various features that make it more efficient and intuitive to use. If you are already familiar with Swift, React Native, or Java, you will be able to tell Flutter apart quickly. Flutter is simple to use since it lacks a set of codes, rules, or rigorous regulations. Developers find this app genuinely easy to work with and use.

Exceptional Performance

Flutter is the only mobile SDK that does not require the Java Script Bridge. The feature’s adoption makes it the most dependable and loyal buddy and companion among all the available substitutes.

An Excellent Platform for Building MVPs

If you want to provide products to your investors on time, the Flutter app is a good choice. The following are some of the reasons why Flutter is important and useful for MVPs:

  • Flutter is similar to native applications and performs better than the competition.
  • On mobile phones, developing an app with Flutter is the most affordable and cost-effective option. This affordability is due to the lack of formality required to construct it separately on two devices, namely iOS and Android.
  • There is only one developer that is responsible for creating MVPs.
  • Flutter includes widgets that are sufficient for creating a relevant user interface for clients.

How Does Flutter Work?

After going through the basics of Flutter, you will now see how Flutter works.

Flutter is not built into iOS or Android apps directly. The rendering engine (written in C++) and Flutter get used for launching apps (built on Dart). All the files created in this manner are attached to each program. Plus, the SDK software gets assembled for a certain platform.

It is similar to game development in that a game’s structure does not get allocated, and the game engine handles functionality. Similarly, Flutter software replaces components of native frameworks with Flutter elements in all programs built on the Flutter SDK.

Even though it impacts the size of the final app, performance is still fairly good — rendering occurs at speeds of up to 120 frames per second. Flutter also simplifies the development process, thanks to native compilation for ARM processors, straightforward rendering, and a set of integrated widgets and tools. It also has a few unique features, such as Hot Reload.

Notably, when you press the Hot Reload button, all code changes are immediately visible in gadgets, emulators, and simulators. The software continues to function as before you pressed the hot reload button: the code changes, but the execution continues.


Flutter is worth exploring if you just have a limited amount of time and resources to build apps. It is as good as it appears, and with each new release, Google developers add additional cross-platform programming tools.

In the end, Flutter has a bright future. If it does stick around, it may provide you with valuable mobile development expertise and prospects in the future.
