The aim of this article is to provide the readers with complete information on the two cross-platform frameworks for mobile app development - and . React Native Flutter These technologies have proved to be the most popular among developers, as reflected in the diagram provided by Statista. In the article, React Native and Flutter are compared on criteria called to simplify the choice of the best tool for developing your next digital product. This debate is extremely relevant nowadays as the popularity of mobile applications is growing day after day opening more and more prospects for businesses and their owners. Source: Statista If you want your business to stay competitive in the market, you will definitely need an app or a couple of apps. The more platforms your app is available on, the higher the chances of your success are. That is why app development using cross-platform technologies is so much in demand. They provide the opportunities to kill two birds with one stone making your app available on multiple platforms and allowing more people to know about your business. Why the comparison between Flutter and React Native? Frankly speaking, the issue of which one is better: or is not new. This topic has already been discussed for quite a while, but the solution hasn’t been found yet. Flutter React Native That is why the question "which tool is better" can hardly have a definite answer. Both frameworks have their pros and cons, as well as their own community of followers. But we hope that after reading this article, you will have a better understanding of and and break down the nuances of these hybrid technologies. And perhaps be more likely to choose your favorite tool. Flutter React Native A few words about Flutter is an open-source, cross-platform SDK (software development kit) created by . Although it is a quite new framework (it was released in 2017), managed to gain popularity among developers very quickly. Flutter Google Flutter uses the programming language, which was also developed by Google. One of the most outstanding features of Flutter is its abundance of versatile widgets, which help to build apps with impressive UI. A detailed description of all useful features and functionalities of Flutter was described in this . Flutter Dart article A few words about React Native is an open-source framework that helps to create sophisticated mobile applications for various platforms simultaneously. React Native was developed by which is why most of the apps from the Facebook family-like , have been created using this tool. The programming languages used by React Native are and which is a great advantage for software engineers since they don’t have to master new tools from scratch. React Native Facebook, Skype Instagram JavaScript React.js, Compared to Flutter, React Native has seen the world a little longer as it was released in 2015. The major benefits of React Native are vast libraries along with a great number of training guides. So now, let’s have a closer look at these cross-platform frameworks and highlight their pros and cons as well as the aspects they have in common. In this article, we are going to compare each of the frameworks according to 8 criteria: UI Components Development process Architecture Performance Documentation Community Testing UI Components The support of native-like components is extremely important for the development of a cross-platform mobile app, as, without it, the app won’t feel like a native one. is bundled with a real army of highly customizable widgets, which help to create as much of an app as you can imagine. Moreover, is armed with a rich number of elements such as UI rendering components, device API access, navigation, testing, and loads of libraries. Flutter Flutter On the other hand, framework provides only . React Native relies greatly on third-party libraries when access to native modules is needed. So because of this, it is inferior to Flutter. Of course, React Native is able to use lots of components and UI elements from but without access to them, React Native is characterized by a smaller number of elements than Flutter. React Native UI rendering and device access APIs third-party libraries Development process It is impossible to predict how long it will take to build an application. This period can vary from several months to a couple of years. The choice of the platform does not really influence the release speed. However, working with simple applications can be due to a large number of components out of the box. Flutter also allows using native code so your application can seem native. Flutter more profitable and faster The development process for since the framework uses native components, which are ready to use. These components help to speed up the process of mobile app development, eliciting many pains. React Native apps is also fast But the most valuable feature of both frameworks is the Hot Reload function, which allows developers to introduce changes to an existing state of the app without having to recompile all of the code from the start, which improves efficiency and accelerates the whole process. So we can conclude that in terms of development speed both frameworks are great. Architecture provides the use of two main patterns when building applications - and . While the former is created by Facebook, the latter is more popular with developers. Both of these structures follow a unidirectional pattern of data flow during development and provide the storage of application state in a central "store", making app components stateless. React Native Flux Redux Since is relatively new to the world of cross-platform application development, most developers find it hard to figure out what architecture is the best option to implement in an application. Flutter offers a number of architectural patterns; each is with. The most popular solution is . At the same time, Flutter makes it possible to if you find these architecture samples more convenient. Flutter highly reliable and convenient to work BLoC (Business Logic Component) use Flux or Redux Performance The architecture consists of two main parts: the and the . In the beginning, it only uses JS. But for the interpretation and rendering of UI components, it must use the JavaScript bridge as it helps to convert the variables to native ones. So, yes, React Native is powerful, but the necessity of using a bridge makes and influences the animations' speed. React Native JavaScript language native language the performance slower , on the other hand, goes a bit behind and the main reason for that is the use of the Dart programming language. Flutter compiles the whole code to the native machine code and between the interface and the code. This makes and results in better and . Flutter avoids any special connection rendering incredibly fast quicker performance Let's look at the operational principles of Flutter and React Native frameworks on the scheme below. Documentation Well-structured documentation and a user-friendly set of tools are essential for software developers. In terms of documentation, Flutter surpasses React Native as it is supplied by . Flutter developers can find any information in seconds. Although it is a relatively new framework, because Dart is similar to Java and Kotlin programming languages. sophisticated and thought-out documentation by Google Flutter is quite easy to switch So it’s not a big deal for a Java developer for instance to start using Flutter for the development of mobile apps. What concerns It would be reasonable to state that it doesn’t provide such thorough and full-scale documentation as Flutter in spite of the fact that React Native is “older”. Nevertheless, React Native can boast a vast and loads of useful guides, which provide opportunities to find necessary solutions in no time. React Native? community of users Community One of the essential issues influencing the reliability of a framework is the community making fundamental contributions to the overall framework advancement. As was released earlier, it is not surprising that it has got a , who can share the knowledge on some new technologies with less experienced developers as well as offer help in solving various problems. Since its release in 2015, the community has significantly expanded, and the interest in this framework only keeps growing. React Native much bigger community of followers React Native As a younger framework, (released in 2017) can’t boast such a vast community but from the very beginning, it was actively supported by software engineers. At the moment, and since the release of a new stable version, the popularity of is sure to increase at a blazing speed. Flutter Google Flutter has got quite a big fan base, Flutter Testing and are cross-platform technologies, which means that the testing time is cut in half. It also makes the QA team easier to work with because they only need to test one application. But surely, if these are different applications on different platforms, they have to be tested. React Native Flutter Developers have all frameworks available for testing React Native apps at the unit level. However, when it comes to UI testing and automation, the situation is not as good. JavaScript is a new framework, and when it comes to testing a new framework, it can be a bit tricky. But Flutter uses , which offers a great unit testing framework to use. So Flutter provides great options for developers to , at unit testing speeds. Flutter Dart test widgets offline Conclusion When approaching the issue of choosing a platform for hybrid app development, you need to analyze a lot of factors such as the budget, time, app size, platforms, and so on. This means that choosing the best solution for mobile development will mostly . However, many experts agree that the expanding interest in , its use, and support from will eventually end up in its leadership. On the other hand, the strong support of the community, its stability, and reliability also make this platform very popular and actively used. depend on the specific task Flutter Google React Native To sum let’s briefly go through the most important features of both technologies: So, for the time being, neither nor can boast of superiority since both technologies have their strengths and weaknesses. Flutter React Native Yes, tool using one of the most popular programming languages, . However, is developing faster, , and is becoming more and more popular with software developers every day. React Native is a more robust cross-platform JavaScript Flutter perfectly adapting to the needs of today's technology world Hopefully, now that you know enough about each platform, you can make an informed decision and choose the one that best suits your needs and expectations.
