React Native vs Flutter (Which is best for startup ?)

Hybrid mobile frameworks are gaining popularity. The appearance of React Native (RN) in 2015 opened amazing opportunities to build apps for iOS and Android using one code base. Hence, it allowed us to kill two birds with one stone and not rewrite the same code twice. Big firms such as UberEats, Discord, and Facebook moved to RN, an effective promotion.

Google didn’t stand aside; they noticed the tremendous popularity of RN. Therefore, Google introduced an alpha version of their own hybrid framework called Flutter in 2017. Flutter also became a very popular framework. The emergence of a framework similar to React Native lead to confusion over what to choose for hybrid mobile app development: React Native or Flutter? However, there’s another important question which you should decide before this: Is it better to develop hybrid or native mobile apps?

We’d like to showcase an easy-to-read guide to which framework is worth learning and using in your work if you need to develop cross-platform apps.


What is Flutter?

Flutter is an open source mobile application development Software development toolkit which is developed by Google. It’s the first release in May 2017. Flutter is written into the C, C++, Dart, Skia Graphics Engine. Flutter works with existing code and ease with which it has been provided has been created by participants and organizations around the world. Flags have been developed by Google. It is also used to develop Android and Android applications. Flutter has been released in May 2017. The SDK is free and launched as a source developer to explore and create powerful, powerful tracking applications around.

What is React Native?

React native is the real mobile application, also open source application development framework which is developed by the Motivate that concepts should be developed on the web for mobile development. Reactive native is used to creating iOS and Android applications. Reactive native was released in March 2015. In this regard, JavaScript is developed. However, the app appearance seems to be a native app.

In this blog, we have compared the two mobile app development frameworks(react native vs flutter) on the basis of various parameters as listed below.

This would help startups choosing the best one for their mobile app development project at an ease. You can also hire developers from top mobile app development companies** **to excel your full stack development work.

The list of parameters on which the comparison has been done is given below:


1. Architecture

React Native

React Native application architecture is known as Flux. Facebook uses Flux to build client-side web applications. Every framework mostly follows MVC framework. The unidirectional data flow is the main concept of Flux. here React takes care of view part and Flux, a programming pattern takes care of the Model in the MVC.


A Dart app architecture library with uni-directional data flow inspired by RefluxJS and Facebook’s Flux. Flutter-flux implements a uni-directional data flow pattern comprised of Actions, Stores, and StoreWatchers. It is based on w_flux but modified to use Flutter instead of React.

Flutter Flux’s implements a unidirectional data flow pattern that consists of Actions, Stores, and StoreWatchers.

2. User Interface (UI/UX)

React Native

Unlike Flutter’s Flat App, React Native App Development requires to use third-party libraries since React Native does not have a UI components library of its own.We used components such as NativeBase, which is an open-source UI components library created by geekyants. React Native Elements, React Native Material Design and Shoutem are other similar UI libraries that are available to the user.

While comparing user Interfaces between React Native vs flutter, React Native is like similar to using HTML without any CSS framework. It is based more on the native components both for Android and iOS also better User Experience (UX) when a user taps into the Operating System.

Unlike Flutter’s Flat App, React Native does not have a UI components library of its own it uses third-party libraries and components like NativeBase. NativeBase which is an open-source library builds a layer on top of React Native that provides you with the basic set of UI components .

Currently, there are 3 main UI libraries:

  • Shoutem UI Components
  • React Native Elements
  • Native Base components


Layout widgets are currently part of the application, new widgets can be included and existing ones can be modified to give them an alternate feel and look, the trend has now changed and the UIs have become more user-friendly, easy to use, increase user engagement, and win grants.

Flutter accompanies built-in beautiful Material Design and Cupertino like iOS-flavor widgets, rich motion APIs, smooth natural scrolling, and platform awareness. Flutter has its own UI components, material design, adaptable widget sets and along with an engine to render them on Android as well as an iOS platform.

Here are a few examples of Flutter Widgets:

  • Shoutem UI Components
  • React Native Elements
  • Native Base components
3) Development Time

The bunch of mobile app development companies that have emerged these days have demonstrated their excellence in the timely delivery of projects and React Native has remained one of the best partners for all these companies. This framework reduces the time frame for mobile app development, adds more to the user interface and takes less time to develop projects.

In the comparison of flutter vs react native, Flutter is new and requires considerable time to develop projects and if we talk about this framework in this particular aspect. React Native has ready-to-use components that help accelerate the landscape of mobile application development without creating much problems for app developers. Flutter also promises high-quality usability, but the framework for application development needs to get more recognition over react native.

**Winner(react native vs flutter): **React Native

4. Stablility Comparision : React Native or Flutter?

The stability becomes an important factor when you are developing a cross platform app. And yet again, we have a tough competition here. At first, Flutter was lacking behind since it had only its alpha version, which was not very suitable for longer projects.

However, last month Google has announced the Flutter Beta 2, which offers improved developer tools and asset system.

React Native was quite stable from earlier and it also enjoys the support of large community of contributors.

**Winner(react native vs flutter): **React Native

5. Programming Languages

RN utilizes JavaScript (JS), which seems to break into software development for every existing platform. It’s used as a default scripting language for web development. Tools like React Native made JS suitable for mobile development, and Node.js introduced JS to server development, as well.

Flutter doesn’t appear to be in the winning position here. It uses a lesser-known language called Dart. This language was created and is being promoted by its originator, Google. However, developers who have tried it out mostly share positive reviews about Dart.

6. Performance

RN includes two parts in its architecture: the JS language and native components. An app built via RN uses JS, but to interact with native components (like OEM widgets, audio, and GPS), a JS bridge is required. It’s used to turn JS variables to native ones. Of course, the conversion creates an additional task that slows React Native down.

What is revolutionary in Flutter? It’s the architecture that enables us to build fast-performing, native-looking apps. Because Flutter doesn’t need a bridge, it can work much faster. Therefore, Flutter is able to run animations at 60 frames per second. The overall speed of an app is so fast that it seems like it’s a browser inbuilt app.

Unit Testing

React Native

Developers have all JavaScript frameworks available for testing at a unit level. However, when it comes to UI and automation testing, the situation is not as bright. Although a number of third-party libraries are available, there is no clear picture there.


Flutter is a new framework and when it comes to testing a new framework it’s somehow difficult but flutter uses Dart which offers an excellent unit testing framework which can be utilized and Flutter provides you with a great option for testing the widgets on a headless runtime, at unit test speeds.



So we have seen a detailed comparison of both the mobile app developmentframeworks for start-ups. Both have their own plus points in terms of stability, performance, documentation etc. as discussed above.

However, it is difficult to decide which one is the winner as they have their own pros and cons. In my opinion, Flutter being new framework would take time to get stable and would travel miles to compete successfully with already popular mobile app development framework i.e. React Native. Hence, React Native is a good choice to start with and can be declared as the winner right now.

No doubt, Flutter can also be a good choice as it creates beautiful mobile apps and can help start-ups to earn well in less time. Moreover, it has an impressive future too.

What is the future of Flutter? Will Flutter kill React Native? What are the benefits that Flutter provides over other popular frameworks?

An Overview of the two most popular and trending frameworks for Hybrid Application Development. Introduction

Hybrid Application development is ruling the Mobile Application development industry rather than Native Development from a couple of years onwards. Business needs are changing from day to day because of an increase in growth and demand. One of the most popular frameworks that became a friend for most of the mobile application developers is React Native, which was introduced by Facebook in the year 2015. until 2015 there was no perfect framework for hybrid application development even though Phone Gap was available in the market. Phone Gap is based on the C# programming language. Developers didn’t love that framework much because there are certain disadvantages in Phone Gap.

The Reasons for the Increase in Demand for Hybrid Application Development

Developing a Mobile Application is really fundamental for the business, but developing the applications for different mobile platforms is becoming an issue for the business investors because of the following problems

  1. They need to maintain different developing teams for different platforms which might lead to a waste of time and money.
  2. It is difficult to find skilled developers, especially in the Asian countries like India, China, Bangladesh, Russia etc… because Apple has a low market in the Asian countries.
  3. There is a development gap between some of the more popular platforms. Deciding which platform to use or focus on can cause confusion.

The above reasons gave birth to the idea of creating cross-platform mobile applications.

There are lots of solutions available in the market but the most popular and trending one right now is by creating compiled apps that can run on both IOS and Android platforms without creating any issues by providing a good performance to the user. The most powerful competitors in that field at this moment are Flutter and React Native. Let’s discuss the strengths and weaknesses of both Flutter and React Native and perform an objective comparison on React Native and Flutter I’ll give the conclusion weather React Native is going to die or not.

React Native

React Native is a powerful javascript framework developed by Facebook for developing cool amazing applications within a short period of time, which is having a capability to run on both IOS and Android platforms. It is developed based on React, it is a Facebook’s JavaScript library for building user interfaces — but instead of targeting the Web Platform, it targets on mobile platforms.


Flutter is a new Hybrid mobile application development framework developed by Google and released in the year 2017. It is built and based on the compiled programming language called Dart, which is agoogle’s general-purpose programming language released in the year 2011. this newly introduced framework will help us to build a variety of critical applications within a short period of time.

One of the advantages of Flutter is that it uses Dart as a programming language, the applications that build with the help of Flutter is able to run on both Android and IOS platform. the applications that are built with the help of Flutter are ridiculously fast in performance.

The Differences Between React Native and Flutter

Till now I’ve completed the introduction of React Native and Flutter and also I explained about why Hybrid Application development is in demand, let’s look at the key differences with React Native and Flutter.

User Interface

React Native

React Native’s UI experience is like using HTML without any CSS framework. While that sounds weird, it actually helps you to build on the native components for both Android and iOS, which provides a better user experience (UX). There is also huge community support, and there are third-party libraries that let you get off the ground in no time.


Flutter has built-in UI elements which are probably called as widgets — All the required shapes, graphics, animations that are required for an application will be created with the help of widgets. If you want to customize your UI easily and quickly, you can use Material Design widgets in your Android application development and Cupertino widgets for IOS application development. However, there is limited support to the community for building and maintaining these widgets. As the framework matures, widgets will be the way to quickly iterate and build Flutter apps.


React Native

Applications that are built with the help of React Native is having an issue with rendering large dataset because React application runs with the help of javascript bridge, we can improve the speed of an application with the use of third-party libraries. However, in the race of a competitive world, React Native can’t able to beat flutter in terms of performance.


Applications that are developed with the help of flutter are having the greatest speed over React Native because it is having an advantage of using Dart. Dart is one of the fastest compiled based languages in the world. Flutter applications don’t require any intermediate bridges to run the application like React Native that’s why Flutter is more powerful than React Native.

Development Time

React Native

React native is having several third-party libraries to design a good user does not require you to write and add separate files for complex UI support, which reduces the development time and improves workflow for the developers. with the help of React Native, developers can develop the cross-platform applications very quickly within a short period of time.


The biggest disadvantage of flutter is that we need to add separate code files for Android and IOS platforms when building complex UI elements. To customize the UI elements we require Dart programming language, Developers need to keep a lot of effort for designing the UI for an application. But once the UI is designed with good looking features then automatically it will give better user experience in both platforms rather than Native Applications.

Developers usually say that Applications that are built with the help of Flutter will give more user experience than Native Applications.

Community Support

React Native

React Native’s community support already exceeded Flutter’s — React Native is currently the most popular framework on Stack Overflow, with community support as proof. React Native is completely open source. there are many blogs and forums to help for beginner programmers.


Flutter was released in the year 2017. it has been almost 2 years and also there is no much love for the Dart programming language in the StackOverflow community. the community support for the Flutter is quite minimal, but the flutter developers at Google are really good, Flutter documentation is really fantastic and easy to follow for the beginners as well.

Code Structure

React Native

React Native has really done a fantastic job in segregating logic, navigation, and design for an application. This allows you to build out complex mobile applications in an easy manner. this is one of the reasons why developers love towards React Native more than other Frameworks.


Flutter doesn’t separate any data, template files, and UI elements. because it uses Dart has a core programming language for building the UI elements even in the complex applications also. So we can simply say that everything is Inline.


React Native currently has steady growth, great community support, amazing code structure, and a really good adoption base for developers. while it comes to Flutter —

It has great potential as part of the future of mobile app development. what I think that

Flutter + Dart + LargeCommunity = Recipe for Success

The only thing that’s stopping most of the developers is that Google’s well-known move of shutting down open source and acquired products.

Hope this article helps you to understand the main difference between Flutter and React Native and the future scope.
