react native vs ionic vs flutter

It is no big surprise that the App market is growing at a faster rate; in fact its expansion has been quite remarkable. Moreover, It’s very difficult for developers to choose the right technology that can shape innovation in this tech-savvy world. Therefore, Companies need to be aware of the latest industry trends to create a competitive edge in the market and adapt quickly. When developing an application, developers need to make sure they are choosing right technology. But, which framework (React Native Vs Flutter Vs Ionic) they should choose seems intimidating for them.

So, there are various reasons why business owners prefer cross-platform app development over native – 

  • Firstly, Cross-platform app development reduces your development time as developers do not need to write different codes to develop an app. So, The same code will work on Android, IOS, and the web.
  • The development cost required to build native apps is higher than cross-platform app development. Hence, Developing apps through cross-platform saves your development cost by 30-40%. 
  • Finally, The maintainability cost of choosing cross-platform is less costly than native because of the same codebase.

Popular Languages Used by Developers to Build Cross-Platform Apps

There are 3 popular languages that developers use to build cross-platform apps quickly-  

1. React Native   

2. Flutter  

3. Ionic   

So, In this blog, we will do a detailed walkthrough of which framework (Flutter vs react native vs Ionic) is best for developing cross-platform applications. 

1. React Native  

React native was introduced in the year 2015. It is an open-source framework that uses JavaScript as its programming language. Moreover, React native enables developers to build cross-platform apps that run on Android, IOS, and Windows.   

Additionally React Native provides native-like app performance. Facebook backs it. Meanwhile, Various apps are built using react native framework, which includes Instagram, Facebook, Walmart, and Airbnb. 

2. Ionic   

Ionic is an open-source SDK framework that was introduced in the year 2013 and it was created by Drift Co. Additionally, This framework is used for developing cross-platform apps using web technologies such as HTML 5 and CSS to run the app on Android and IOS.   

 3. Flutter   

Flutter was introduced in the year 2018 to create high-performing applications. Futter is backed by Google so it is receiving massive support from the Google team. Moreover, Flutter is best at developing native-like applications. Moreover, Flutter is a new player in the market in developing cross-platform apps that run on Android and IOS.   

In addition, many top brands have leveraged the Flutter framework in developing scalable mobile apps including google pay, Alibaba, etc.   

Difference Between React Native vs Ionic vs Flutter

1. Programming language  

Firstly, React native combines react framework with JavaScript to deliver native-like experiences. React uses JavaScript as its programming language. Moreover, It is mostly preferred by developers as it is widely used in developing hybrid apps.   

Ionic programming language on the other hand , uses HTML 5, CSS, and JavaScript to develop high-quality apps for Android and IOS.  

Lastly, Flutter uses Dart, an object-oriented programming language to create cross-platform apps that work well on Android, IOS, and web.  In fact Google developed Flutter. 

Flutter vs React Native

Which framework (react native vs Flutter vs Ionic) does the developers use? 

If someone has expertise in an object-oriented programming language, then Flutter is good to use. So, If an organization has angular developers, they can choose Ionic. However, if someone has skilled React developers, then they can develop apps using react native framework. 

2. Performance  

When it comes to developing mobile apps, the performance aspect can’t be ignored.   

Firstly, React native uses native APIs and components to develop applications that are similar to native apps. Furthermore, The applications developed using react native framework provides high performance.  

Secondly, Ionic delivers better performance. Though Ionic offers a native-like app appearance, it does not develop native-like Apps. Hence, Flutter is the clear winner here.  

While, Flutter offers amazing performance (60 Frames per second) as it does not use JavaScript bridge to interact with native components.   

3. Popularity  

Most Popular Framework

React native is a more popular framework as it has a large community of developers. In addition to this, The number of react developers is increasing as react native framework uses popular JavaScript libraries. Additionally, react native framework is used by tech giants such as Walmart, uber, tesla, etc.  

86% of web developers use ionic, but it has gained huge support from the developers’ community as it is the oldest framework than react native and Flutter. 

On the other hand, Flutter, a new framework that entered the market, has seen increased growth in the number of developers. Though it has a smaller user base, its growth of development is expected to skyrocket than react native and Ionic in the coming few years.   

Additionally, Flutter is backed by Google and Google uses Flutter to develop its applications. Flutter framework is used by many companies such as invoice ninja, eBay, google, etc.   

4. User Interface  

 React native uses React JS library and native UI controllers to provide a native-like experience. Therefore, It uses third-party libraries as it does not have its UI components.   

Secondly, The ionic framework does not make use of any native elements. It uses web technologies such as HTML and CSS to give a native-like appearance to apps.   

While, Flutter has its own UI components, widgets library, and UI rendering engine to create user-friendly apps that work well for multiple platforms.   

5. Pricing  

React native is an open-source framework because it allows engineers to use various libraries for free.  

Though Ionic is a free, open-source framework, it offers a pro version called Ionic Pro. Additionally, Ionic Pro allows developers to expedite their development process.   

Flutter is also an open-source SDK that enables developers to use widgets and libraries for free. Moreover, The cost of flutter developers ranges between $35-$65 per hour. 

6. Execution of code   

React native is based on this principle “Learn code once, Use it everywhere.” Developers need not worry about wasting time and efforts in creating separate codes for multiple platforms.   

Secondly, One advantage that makes react native stand out from other frameworks is that it uses the JavaScript library with react to develop scalable apps.   

Whereas, The ionic framework uses the principle of “one codebase and all platforms,” which means developers can build highly interactive apps quickly.  

Flutter uses Dart programming language, and Dart is an advanced as a result and comprehensive language. Additionally, Flutter has rich features and platform-specific APIs to create interactive mobile applications. 

7. Maintainability  

It becomes challenging to maintain a cross-platform app that is developed through react native framework. However, it has a huge community support from developers. Moreover, Different plugins are used to ensure proper maintenance of an app.  

Ionic has less community support than react native. Hence, It is difficult to do backward compatibility.  

On the other hand, Flutter, being the new framework, has huge support from Google. Also, It is easy to maintain an app using Flutter framework as Google regularly tests the app against new versions.  

8. Availability of Developers  

The availability of react native developers is enormous.  React native framework has a community of more than 5000 app developers.  

While, Flutter uses Dart programming language. Dart is a modern and object-oriented language, and there has been a rising trend as most developers wanted to become proficient in this. Furthermore, object-oriented developers can quickly learn Dart to develop cross-platform apps.

Additionally, The demand for angular developers is fading away with the increasing popularity of Flutter. Therefore, it has become a least popular choice for developers to opt-in.

Q1. Will Flutter overtake react native?  

We want to refrain from commenting on which framework will dominate others in 2023; however, we can discuss the current trends and popular choices among developers. But according to a Statista survey, Flutter stays ahead of react native in 2021 and is considered the most popular platform for developing cross-platform apps. 

Q2. Whose performance is better: React native or flutter?

Flutter performs faster in developing mobile apps because it does not use any JavaScript library to interact with native components. Additionally, Flutter can provide 60 frames per second (FPS) performance which is much higher than what React native renders (40-45 frames per second). 

Q3. How do I decide which platform is best use for me?

Overall, There is no single answer to this question. On the whole, It depends on various things given below-
Firstly, If the developer has expertise in developing a cross-platform app, then he /she can use that framework be it React Native, Ionic or Flutter  
Secondly, It depends on the intent of an app. Additionally, Moreover, If an app has 3rd party integrations, then it is better to choose the platform for which you have SDK which is provided by 3rd party integration providers.
– Thirdly, If an app has a lot of data to show on the user interface, then you can choose either react native or Ionic because Ionic has less performance and extensive operations.
– Lastly, If you are doing lot of CPU and native operations then using Flutter is the profitable option in this case.
