The world of app development is constantly evolving, and businesses are now realizing the importance of cross-platform app development services. With cross-platform app development being cost-effective and helping to increase revenue, it has become an essential aspect for many companies.
Two popular options for cross-platform app development are Flutter and React Native, which are bringing a paradigm shift in this realm. One of the main reasons for their growing popularity is their UI libraries, which offer flexibility to developers. These libraries allow them to create more compelling and durable apps that perform well in the market.
UI libraries are essential for apps to work consistently on both iOS and Android platforms. They also enhance the overall app navigation process, resulting in an improved customer experience.
In this blog, we will delve into the nuances of the Flutter UI framework and React Native UI framework, exploring their similarities and differences. We will also highlight the top 10 Flutter UI libraries and React Native UI libraries that can be used to create stunning app designs.
Difference between React Native and Flutter

Before diving deep into the details of the top React Native and Flutter UI libraries, it is essential to understand the difference between the frameworks. Although used for cross-platform application development, both Flutter and React Native are unique in their own right. Let us have a look.
1. User Interface
It is important to understand that React Native does not have its own UI components library. Thus, it is essential for the framework to use third-party libraries such as NativeBase. On the other hand, UIs in Flutter UI framework are easy to use, more user-friendly and help in increasing customer engagement.
2. Unit Testing
In React Native for unit testing, the developers have the entire set of JavaScript frameworks available. Moreover, the picture is not as bright in UI and automation testing for React Native.Despite the fact that the framework has a myriad of third-party libraries, the overall picture is not as bright.
Flutter uses Dart so despite being a new framework, it offers excellent unit testing. There are great options for quality analysts to test the widgets on a headless runtime with Flutter.
3. Community support
React Native is the popular open-source framework on Stack Overflow and the numbers back this fact. It has 101k user subreddit, 68K stars on Github and 9000 support on Stack Overflow and user Discord chat. Flutter ui library is still growing, it has 30K stars on Github, 4.5K user subreddit, and 740 users on Stack Overflow and Google Group. React Native ui library has a bigger community support compared to Flutter ui library.
Since in cross-platform app development, the app is designed for both iOS and Android, stability becomes an important factor. Flutter UI library offers improved tools to the developers and assets system for better stability. Moreover, as React Native has a large community of contributors, the apps developed through it are stable as well.
4. UI Library
When looking at a flutter ui library, it is important to understand that React Native does not have its own UI components library. Thus, it is essential for the framework to use third-party libraries such as NativeBase. However, flutter ui library is easy to use, more user-friendly and helps in increasing customer engagement, making it an ideal choice for UI design.
In the React Native ui library, for unit testing, the developers have the entire set of JavaScript frameworks available. Although the framework has a myriad of third-party libraries, the overall picture is not as bright for UI and automation testing. Flutter ui library, on the other hand, offers excellent unit testing as it uses Dart, which makes it easier for quality analysts to test the widgets on a headless runtime.
