Developing a comparison for the two most popular cross-platform frameworks; Flutter vs React Native is a tricky task. Because it all depends on why and how you use UI frameworks while developing hybrid mobile applications. Flutter and React Native are open-source platforms that allow writing native mobile application codes from scratch, offering multiple unique features.  

React Native Overview  

React Native uses JavaScript language to build hybrid applications. To develop React Native applications you require expert JS developers. Expo is the free core feature of react-native that is useful to embed and execute react native hybrid projects. Furthermore, react native offers a convenient conversion from React to react-native; that’s why it has become the center of attraction for professionals.  

Flutter Overview   

Flutter is a UL toolkit useful for developing dynamic, open-source, and responsive hybrid applications. Flutter hybrid applications are written in Darts, an object-oriented language. According to flutter developers, dart-based applications are powerful, fast, and offer control for rendering stack.    

Evaluating Flutter Vs React Native  


React Native  

React Native offers web apps a native look and performance. React Native code consists of two different parts; native and JS codes. React native developers can optimize app performance by manually fixing coding errors.   


Flutter does not utilize web views and operating system native controls. Flutter framework allows developers to develop widgets using Skia Engine. Therefore, the compilation of flutter applications with C and C++ libraries enhances their performance. But flutter is dependent on packages; you need to add packages if you want to develop a larger app.   

Code Structure    

React Native  

Direct styling with JavaScript allows developers to build MVC from scratch. Comparing with react, react-native has intuitive architecture. Furthermore, setting development for react native is very simple by using React Native CLI or Expo. Expo is a free tool that enables you to build and deploy react-native applications with native coding.   


The main dart file is the most important because it executes code for both iOS and Android. This part only consists of a simple and short code and presents an application overview. RunApp function usually runs widgets that should be simple to understand and execute.   

Development Time   

React Native  

React native coding is faster because of numerous libraries that optimize the designing process. Moreover, the availability of custom libraries also assists the development process. But development usually depends upon developers’ expertise and application architecture.  


Flutter hybrid app development takes less time because developers can reuse their code for different applications. Furthermore, developers need to write one code for all platforms that make it time-effective.

Critical Analysis Flutter vs React Native  

Most of the time businesses are struggling to analyze flutter vs react native. Both of them are emerging technologies. No doubt they have multiple benefits, but still, they have some flaws too.  

React Native Pros and Cons  

  • React Native uses JavaScript that is well known to everyone, unlike flutter where you need to explore Dart.   
  • React Native is a valuable instrument to create minimal products because of JS.   
  • React native has a bigger community solution and libraries that make it reliable.   
  • While coding in reacts native you need to write style design from scratch, or you can find the design in spades.     

Flutter Pros and Cons  

  • Flutter offers a multi-tier architecture that is best for UI customization. It also helps developers to animate text, images, and videos.  
  • Flutter has updated with a wide range of new platforms from single code.  
  • Flutter application usually does not support web browsers.  
  • Flutter applications are 3 times larger than native apps.    
  • Flutter has messier styling because of the separation between templates.  


Flutter vs React Native a challenging task where react native is the best choice for applications with ordinary functionalities, and flutter is well fit for cross-platform applications. However, flutter is still improving its framework; you need to consult an experienced development company before choosing the platform. If you do not have in-house expertise, you can ask OptimusFox for hybrid app development services.
