Flutter vs. React Native – What to Choose in 2021?

Flutter vs. React Native

Let’s say you’ve decided to develop a cross-platform mobile app. What do you choose, Flutter vs. React Native development? What instrument will provide better performance for the app? Which one has a faster response? Is it easier to find a Flutter or React Native dev and what are the costs? Depending on the goal you pursue, these are the main factors you have to take into consideration when working with boat instruments:

UI and Design

The main idea of Flutter is that you can create your own interface by using widgets. These include not only various buttons, texts, and pictures; they are also animation, different options, sensor integration, etc. Widgets define how the interface will look depending on configuration and its position. When the position of the widget changes (for example, if a user presses the button,)it rearranges its description, and the interface changes as well.

Flutter has two widget packs, Material Design and Cupertino. The first Group imitates and native Android design because Material Design is the programming language oriented for Android and developed by Google. The other group is oriented toward iOS. Because of that, Flutter apps look seamless and work for both platforms. But most importantly, Flutter has a unified UI for every device, even for those with the older ОS versions. 

When it comes to React Native, it works with JavaScript. Flex and other components describe the UI while JavaScript is responsible for logic. Everything gets embedded into JSON.

How Fast Does It Take to Develop an App? 

Both frameworks have mechanisms embedded to increase the speed of development. One of the key components of Flutter is called Hot Reload; it allows developers to foresee the effect of changing the code. This option is more than comfortable for the collaboration of devs and designers because this parallel task increases the speed of development. Moreover, Flutter consists of two widgets worthy developers can place one into another. This principle gets the job done quickly, facilitating the work. There are many ready-to-use widgets, but the dev can write their own. Flutter is also easy to update; all you have to do is write “flutter upgrade” for the console, and all of your components will be updated automatically.

When it comes to React Native, it has the option called Fast Refresh, allowing devs to input your code directly into a working app. But when you work with React Native, there might be some problems coming along the way. For example, your attempt to update React Nativ might lead to crushing the libraries. The instruments for automatic updates sometimes don’t work, that’s why devs have to update some components manually.


Flutter is supported by Google and is a result of open-source software. The community organizes events, such as Flutter Engage where you can get the latest news, talk to Dart representatives, get your hands on the new strategies, and many more.

React Native is supported by a Facebook open-source community. Besides, it has a Discord community called Reactiflux, a bunch of forums, and cooperative events. One of the main events dedicated to React Native is called React Conf.

Libraries, Instruments, and Plugins

Although we are used to thinking that Flutter’s ecosystem is not so widespread, the framework has a wide variety of ready-to-use packages with more than 14000 elementsю because of it, developers can increase productivity, as well as turn URL-addresses and emails into interactive embedded links for e-commerce services.

React Native has a wide variety of libraries. For example, it has a list of high-quality add-ons called awesome-react-native. However, in some cases, you have a risk of bumping into old or low-quality packages.
