Flutter x React Native

(6 minutes of reading) It is impossible to program nowadays without using a framework. There are many on the market and Flutter and React Native are two of the most popular ones. What's the difference between them? And which one is better to use in your project? Come read our text today to understand a little more about it.

Flutter x React Native

(6 minutes of reading)

Flutter and React Native are two of the most used frameworks nowadays in the mobile development area. But before we start talking about them, do you really know what a framework is?


Framework is a programming architecture that brings together a variety of generic codes with the aim of simplifying, structuring, and facilitating the web development process. That is, they are ready-made codes that can be used in the development of applications and websites. The purpose of this tool is to apply ready-made features, commands, and structures to ensure quality in the development of a project. Its main objective is to solve recurring problems with a more generic approach. It allows the developer to focus on the “problems” of the application, not on the architecture and configurations.

Its main objective is to make the developer focus more on application problems since a framework solves recurring problems.

There are many framework options nowadays and two of the most used ones are Flutter and React Native.

Let's talk a little more about these two frameworks now.


Flutter is an open-source framework on the BSD License and multiplatform. Flutter has Dart as its base language, a language also created by Google that is very similar to JavaScript.

Flutter allows the application developed from it to run on any type of platform: mobile, desktop and web.

So, it can be used for development on Android, iOS, Windows, and all other operating systems.

We see many companies betting on Flutter, such as: Google, Alibaba, Groupon, Nubank , iFood , among others. One of the main reasons for this is the way Flutter works for creating applications.

Structural elements in Flutter such as menus, layout options, buttons and more are widgets and are optimized to decrease time spent on testing, ensuring there are little or no compatibility issues with different versions of an operating system.

And when creating an app with Flutter, your code is compiled into the base language of the device, that is, the applications are truly native and therefore able to access device resources without the help of third parties and with greater performance.

You can use them through the framework's ready-made packages or create them from scratch.

We cannot ignore that Flutter's acceptance curve is increasingly on the rise, and do you know why?

With Flutter, the programmer can create apps for both Android and iOS using the same base code, that is, there is no need for specific coding for each operating system. In addition, there is a great expansion of its community, easy access to the programming language (Dart) through the official website and the learning curve is relatively short compared to React Native.

Using only the Dart language in Flutter you can develop apps that in React Native would require you to be knowledgeable in three other technologies: HTML, CSS and JavaScript.

React Native is a framework developed by Facebook and based on JavaScript to create native apps for iOS and Android. It is an alternative to cross-platform hybrid app development tools like PhoneGap.

The framework assists in reusing existing code and libraries, which speeds up the development process. The framework's design philosophy aims to be easy to learn, use, and extend by providing a reliable way to manage the application lifecycle in terms of state management.

It is worth noting that React Native is one of the most popular frameworks among developers because it provides a nice upgrade from HTML5/CSS3 web apps to native mobile apps with little effort on the part of developers. Today it is widely used by companies like Instagram, Facebook, Tesla, Discord, among others.

The community has also been very active in terms of supporting new features, APIs, and libraries to make React Native even more flexible and easy to use.

Can we compare these two frameworks? It is a very difficult task, despite being direct competitors, the choice of each one is very related to the project you are working on.

What we can say is that both frameworks have very similar characteristics. Both Flutter and React Native are new and with that, not very stable and mature.

We can use both to build a nice cross-platform MVP with the possibility to reuse the code. We can also point out that so much React Native and Flutter reduce development time and project expenses.

As previously mentioned, each project has its needs, and the choice depends entirely on what the business specifically needs.
