Since we got into the 21st century, every person has a smartphone to connect themselves to the web. Now every business wants to reach their customers through smartphone apps. As it provides better services to the customers and it further helps companies to grow their user experience. Nowadays, these small applications have solutions to every single problem. With better devices, the speed and reliability of these apps are increased.

There are majorly two operating platforms for smartphones: Android and iOS. So for the best mobile app development companythere is always a challenge- which framework should they use to build their apps? Flutter and React Native are two major app development languages that can be used to build apps. Both of these frameworks are cross-platformed and are rated among the best software for developing apps.

In this blog, we will go through complete features and a comparison between Flutter and React Native. 

An overview of Comparison

So both Flutter and React Native is currently the top software to build applications. It makes it hard for us to choose one out of them. We will get into the depth of features and limitations of both software. It will help you to determine which one is better for you.  


This open-source UI software was developed in 2018 by Google and Community. It is written in DART language, which is based on object orientation. The primary purpose of this software is to enable better customer services by making apps more optimized and well-defined. It is among the top rankers of app development software. 

It is free to use for creating cross-platform applications. It is used among 68% of developed countries. Flutter builds +150,000 apps on the play store. 

Special Features

  • Can create MVP mobile apps
  • Highly optimizing in terms of functions
  • Better with hardware requirements
  • Easy user interface with better widgets
  • Plugins can be installed with less hassle
  • Integrating applications is more straightforward with FLutter

React Native

React Native is a Java language-based open-source platform for developing applications. The framework allows you to build native rendered apps for iOS and Android. In addition, you can create apps for different platforms with the same codebase. For example, react Facebook and Community made native app development software in 2015. You can also write apps in other languages like JavaScript, Objective C, and many more. 

The popularity of this software can be known because- 40 percent of developers will use React Native in 2020.  

 Special Features 

  • Simple to use and it supports cross-platforms
  • The codebase can be utilized towards different platforms
  • Prototype applications can be designed
  • APIs can be used with React Native
  • Supports different languages
  • The community trusts this software

 Limitation and Advantages – Flutter vs. React Native

 Advantages of Flutter


It is the most popular feature of Flutter as it uses unique design models to build an application. Top-notch widgets can be made by Flutter, which is based on Google models. It provides high-end optimization and works superior to other open-source software. In addition, it gives a better engagement to the customers and helps them use the apps more effectively.

Integration Capabilities

Flutter can easily integrate with either Objective C or Swift when it comes to iOS. Java can enhance the android experience. There is less repetition of code writing. It helps with the performance of apps. They can work faster hence improving efficiency. 

 Easily Share Codes

It helps with MVP development as the code sharing is smoother between platforms. This further adds to the advantages of Flutter.


The Flutter works on a high-performance engine called Skia. It is an open-source graphics engine that enables the user to build custom design apps that provide a better experience to customers. It is crucial when you are making an application with close touch. 

 Better Shipping Time

It saves from the time required for the software to build apps as you have to test only one codebase. 

 Limitation of Flutter

Third-Party Library

As Flutter is among the latest ones, it does not have a better library. Though it is increasing its choices, it still has limited access to the library. It is also limiting third-party tools, which can further add to the convenience.

 Larger Size

The cons of Flutter are that it builds apps with large sizes and affects the application's runtime as the user has to give more space to store apps. On the other hand, the small size helps to increase performance which is a limitation in Flutter. 


Programmers have to learn DART before using Flutter. Therefore, it increases the overall cost of the project. Learning another language can cost more hence making it long and expensive.  

Advantages of React Native

Better Performance

React Native creates native APIs and UIs other than existing threads that help with the app's performance. 


It is equipped with an ecosystem that renders the application on different stages. Providing you with better UI 

 Hot Reloading

Users can add codes to the existing apps that help the developers to deliver a better update. It allows a developer to change the source codes of a live application. 

 Simplified Interface

It has a simple easy to use interface that helps developers to build applications with more ease. 

Limitation of React Native

Lacks UI Components

If you are building any application, the React Native API may not support some UI elements. It is because it fades the experience of UI.


Multi-processing makes apps slower because high-end codes use more resources. Hence the performance is sacrificed when a parallel thread is used.


After going through different aspects of both frameworks, we cannot say that any platform has a better hand against others. The decision is entirely biased towards the requirement and resources of your project. Both of these frameworks can build a cross-platform application.

The significant difference is that if you are into heavy apps that require native programing. Then Flutter is the software of your choice. The react Native is more suitable for plug-and-play models. If you want to develop an application with a personalized touch, you should go with Flutter. But you have to learn DART before switching to Flutter.
