Features of React Native
One of the essential steps in mobile app development is designing the UI (User Interface). React Native is considered as one of the best frameworks for creating the app UI because this framework has excellent rendering capabilities and is thoroughly responsive. Thus, React Native is a top choice among developers for front-end development.
This framework provides more accessibility. There are also changes in action support, flags, roles, and many more. Moreover, there are many other enhancements such as better android keyboard accessibility options, support for “reduction motor,” CALayer for drawing text, etc.
The live reloading feature of React Native empowers developers to easily check the aftereffect of the most recent change that they have made. This amazing feature is not found in native frameworks.
You can use one single code in React Native for Android and iOS deployment. Almost 90% of the code can be reused in this framework. Hence if you hire React Native developer, the development time and cost are reduced to half.
NPM for Installation
Using this framework, developers can get rid of tedious installation processes. How? The React Native uses NPM (Node Package Manager), which eases the whole installation process. If you understand NPM download well, you can use this framework without any hands-on React Native framework.
What is Flutter?
Flutter is an open-source framework used for building native mobile applications. It was created by Google and launched in May 2017. Due to the amazing features and functionality of Flutter it has become the top choice among the developer’s world. Like React Native, it also has cross-platform compatibility, providing cost-effective solutions.
It consists of two parts:
- SDK (Software Development Kit)- It is a collection of tools that are used to compile code into native machine code for both platforms Android and iOS.
- UI Library- It consists of reusable UI elements such as text inputs, buttons, sliders, and so on. We can personalize all these UI elements as per needs.
Flutter uses the programming language Dart, which is a typed object programming language focused mainly in front-end development. So, to leverage this technology fully hire professional front-end developers.

Features of Flutter
With the help of this feature, changes made by developers in the code can be seen instantaneously. As the changes made are reflected within the second; hence developers can fix the bugs immediately. It saves the cost of the project and time of application development. Moreover, hot reload gives designers and developers full freedom, boosting their creativity.
This framework provides developers to use existing Obj-C, code Java and Swift, hence ensuring native features which are platform specific. The platform-specific widgets are used for Android, iOS, and Google Fuchsia. To access the different platform-dependent functionalities, these widgets can be integrated into Flutter mobile applications. Hence, Flutter technology can easily incorporate third-party APIs and integrations.
As Flutter is based on Dart programming language, hence the application required minimal code to implement the whole functionality. Dart uses JIT and AOT compilation, wherein JIT enhances the development system by refreshing the UI without needing to build a new one. Thus, this framework accelerated overall functioning, startup time, and performance.
The widgets are given an upper hand in Flutter, and everything is considered as widgets. A widget can be a menu, colour, or padding. You can even customize widgets as per project needs. This framework has all sets of widgets, from Cupertino pack to Material Design, ensuring a glitch-free user experience.

2. Programming Language
Flutter, on the other hand, uses Dart programming language. As Dart supports most of the object-oriented concepts, its syntax is easy to understand for Java developers. It is easy to get started with this programming language with the help of detailed documentation available on the official website.
3. Technical Architecture
It’s important to understand the technical architecture of React Native vs Flutter before choosing anyone for your next project. If we know the internal architecture of the frameworks, we can make an informed decision.
Flutter uses Dart programming language. The Dart framework includes most of the components, eliminating the requirement for a bridge to interface with native modules. The various frameworks in Dart(Material Design & Cupertino) provided all the necessary technologies to develop highly robust mobile apps. Moreover, the Dart framework uses the Skia C++ engine, which contains all the composition, protocols, and channels.
The documentation of React Native is not as straightforward and poorly done. When you hire React Native developers, you will see they often look for third-party sources to get the kind of documentation your project needs.
Flutter documentation is easy to read, straightforward and streamlined. The videos and graphics available with the framework help developers easily optimize a current project
The installation should be straightforward so that newbie developers can easily learn it. Let’s see out of React Native vs Flutter who is the winner in terms of installation.
To install the Flutter framework, we must download the binary for a specific platform from GitHub. If you are installing for macOS, one additional step is downloading the flutter.zip file. This file is added as a Path variable.
However, Flutter improved the installation process with the help of supporting package managers like MacPorts, YUM, Homebrew, etc., to avoid this extra step.
It is not easy to decide between React Native vs Flutter, which has better performance. Because when we talk about performance, we have to consider a lot of factors like a codebase, type of app, animation, transition, layout, app size, data passing, and many more. Let’s see who is the winner.
Regarding performance, the approach of React Native is quite different from Flutter. Instead of the whole application getting compiled to C/C++ or a native language, only the UI components are compiled. For any action required through a bridge, the JS code runs in a separate thread and communicates with native modules.
While in the case of Flutter, the whole application is compiled using the C/C++ library. Unlike React Native in Flutter, the application is compiled. Hence mobile apps have better native performance.
7. Project Size
On the contrary, Flutter apps have huge file sizes. Thus, the mobile app developed with Flutter takes up more space due to its larger build sizes.
8. Device Compatibility
React Native and Flutter support Apple devices from iPhone 4s and above and Android devices with ARM processors. Moreover, both support iOS and Android simulators for developing apps. Let’s have a look at React Native vs Flutter compatibility.
React Native supports Apple devices iOS 11 and above while Android devices of API level 23 or above. It supports Expo-based apps for Android 5 or iOS 10 and above.
Flutter supports Apple devices of iOS 9 and above and Android devices of API level 19 and above.
9. UI Component and Development API
While developing cross-platform apps, ensure that the framework has an API to access the native modules easily because a mobile app won’t feel like a native app without the support of the native component.
This framework provides just device access APIs and UI rendering. Thus, React Native depends on third-party libraries to access most of the native modules. Check out the entire list of official APIs and development components.
This framework consists of a rich set of components; hence, third-party libraries are not needed. Flutter is bundled with device API access, UI components, stateful management, navigation, testing, and many other libraries.
Testing the code will help developers to fix the bugs and issues. Every technology has a testing framework that enables developers to create UI tests, units, and integration for the apps. Let’s check out React Native vs Flutter, who is the winner in terms of testing support.
In React Native, there are only a few unit-level testing frameworks. For snapshot testing, we can use tools like Jest. While regarding UI level testing and integration, there is no official support from React Native. React Native uses some third-party tools like Detox and Appium to test a mobile app, but they are not officially supported.
On the other hand, Flutter comes with rich testing tools to efficiently test the app at the widget, unit, and integration levels.
11. Community Support
A community helps developers to learn from each other’s experiences and help each other to solve the issues that arise during application development.
Since its launch in 2015, this framework has gained immense popularity. React Native has a developer ecosystem of over 10,000. Currently, it has 2359 contributors on GitHub. Hence, it is correct to say that React Native is backed by tremendous community support.
Compared to React Native, Flutter’s community of developers is small. Flutter was launched in 2017, and although slowly and gradually, its popularity is increasing, there are still not enough resources for developers to solve issues quickly and effectively.
12. DevOps and CI/CD support
Continuous integration and delivery practices are vital for any mobile app to avoid releasing buggy code and get constant feedback.
This framework doesn’t come with any official documentation of CI/CD. Read this article to understand the CI/CD setting process for React Native apps and constant integration and delivery tools for iOS, Android, Cordova, Ionic, and React Native apps.
Regarding Flutter, it has a rich command line interface that helps developers easily set up CI/CD. Moreover, it has a separate Continuous Testing and Integration section, which includes links to external sources.
13. Code Reusability
This framework allows developers to write code once and reuse it across the application. But compatibility is not guaranteed on each type of mobile app platform. Thus, React Native developers are often required to load a varying set of components that work. It results in an increase in the cost of React Native app development.
Flutter is based on Dart programming language; hence the code reusability is more. Proficient developers of a Flutter development company define a single UI widget tree and reuse the defined logic.
14. Development Time
Regarding development time, out of React Native vs Flutter, Flutter loses. Because the Dart language used in Flutter lacks the support of IDEs and text editors, it takes more time to develop applications.
