React Native VS Flutter


UI Frameworks Intro

Choosing between these super popular frameworks, React Native or Flutter, may be a tricky task. It all depends on what for – and how – you’re using these UI frameworks when building your mobile app. Flutter and React Native are both open-source frameworks for writing native mobile apps from scratch.

We’ve gathered the most crucial points to compare these technologies, and your question, React native vs Flutter which is better, will be fully explained in this guide.

Developed by Google, Flutter is a framework built to suit Google’s development tasks. And, thanks to this fact, Flutter has gained popularity. In contrast, React Native is like an adaptation of all existing technologies for mobile web development. If you’re familiar with both of the technologies,  both of the frameworks, you could have heard an opinion that Google tried to absorb the best aspects of React Native to create their own tool. 

Someone has compared Flutter’s Dart to such high-level programming languages as C#, Kotlin, or Java. At the same time, he has some features of JavaScript. But keep reading to see the whole picture of the mobile development market.

What is React Native?

React Native is a well-known cross-platform framework used for building mobile apps, using popular JavaScript language. It appeared a long time ago, in 2015. So, deciding to start coding in React Native you will undoubtedly find your support in the face of professional JS engineers. 

Provided by Facebook, such leaders as Discord, Tesla, Shopify, Pinterest, Delivery Hero, Walmart, Baidu, Bloomberg, UberEATS, Vogue, Soundcloud, Skype, use in their apps React Native technology for their modern and interactive UIs.

One of the core features of React Native is Expo. Expo is a free and highly useful way to embed and run React Native projects for web, iOS, and Android platforms. 

React Native developers tend to use Flux or Redux state containers when working with the architecture of an application. React Native functions don’t produce side effects that return what the views look like at any point in time. 

Also, React Native is loved for the highly convenient transition from React to React Native thanks to one ecosystem and really huge community of professionals. 

What is Flutter? 

Flutter is a UI toolkit for web and mobile app development, broadly used for making dynamic, responsive, and open-source applications from a single codebase. Flutter was created by Google in May of 2017 for building cross-platform applications.

Flutter apps are written in the Dart programming language, the object-oriented and class-based language mainly for building fast and powerful apps with control over the rendering stack. Dart is really easy to learn, its syntax is really similar to Js. Flutter is loved for its developer friendliness and beautiful widgets within Flutter’s technical architecture. Btw, Flutter is utterly embraced by Material Design. Such huge products as Google Adwords,, Alibaba, Tencent, and Hamilton apps were made with Flutter.

At first, Flutter was made for OS, and Android development, but later Flutter was released for desktop and all the other popular platforms. One of the crucial points of Flutter is clean UI interfaces of the apps which will run smoothly on Mac, Linux, iOS, Android and Windows, and the web. That can be equal to 6 products with a single codebase. It is a faster, and easier way in terms of long-lasting project development. The evident minus of the cross-platform tools is that they have many limitations in terms of implementation and performance.

In Flutter, you work with widgets, stateless and stateful. Widgets are the same as components in React Native. But, Flutter widgets are not adaptive, so you have to perform platform-specific adaptation manually. The main architecture of Flutter is BLoC (Business Logic Component). Well, what is BLoC? Business logic, also called domain logic, is the way of your entities to be in relation to the business problem that you’re trying to change. All the business logic components (BLCs) are separate and prepare the frontend data for sending to the backend and prepare the backend data for display in a visual application component (VAC). In other words, BLoC is like an intermediator, responsible for managing the relations between its components: widgets submit events; other widgets respond. The main plus of BLoC is that it helps to separate the presentation layer from the business logic that enhances the coding and testing process.
