Facebook’s React Native and Google’s Flutter are two examples of the most popular and well-known technologies used in cross-platform application development today.

Since React Native and Flutter are designed and presented by professional and powerful companies, most activists in this field are always looking to compare them with each other. Therefore, in the following, we will examine and compare React Native and Flutter from the perspective of a developer. But before that, it’s not bad to see what React Native and Flutter are and what technology needs in today’s world.

What in the world today needs to react natively and flutter?

Given the vast world of mobile applications, which is growing in size every moment, every company needs to compete with others to stay in this space. So, companies are looking for a way to produce apps compatible with iOS and Android in the shortest possible time and with minimal resource requirements.

Google and Apple have provided native technologies and tools for designing and producing applications for their audiences. Xcode and Swift can be used to design and produce suitable applications for the iOS system. In contrast, those interested in producing Android applications can use Android Studio or Kotlin / Java.

Engineers and programmers who intend to produce applications with each of these technologies must learn how to work with them separately.

Also, if a company intends to produce its application and publish it in both iOS and Android versions, it must spend a lot of time separately on each of these technologies.

Thus, intermediate technologies such as react native, and Flutter emerged to allow programmers to design their applications on an interface platform without learning the skills of working with technologies such as Swift, Xcode, and the like under a specific programming language. Then, it will be adapted to iOS and Android systems on the same platform and made available to the public.

Familiarity with React Native and Flutter

Facebook started the React Native project as an open-source company in 2015. Flutter, on the other hand, was introduced and launched by Google in 2017.

Both technologies are for helping app developers and developers, intending to eliminate the need for them to learn Android and iOS-specific technologies, as well as save them time and energy.

Although React Native and Flutter were released two years apart, since they are two powerful manufacturers, they must be compared in different ways to better understand them.

React Native and Flutter can be compared and examined in terms of the following indicators:

• Programming language
• Technical structure
• installation method
• Set up and receive approvals
• UI and API components developed
• Developer efficiency
• Support forums
• Testing and testing support
• Production and publishing automation support
• CI / CD support

In the following, we will compare these 10 indicators of react native and flutter.

1- Comparison of react native and Flutter in terms of programming language

As mentioned earlier, a strong point in both react native and Flutter technologies is the ability to write applications in a specific programming language for iOS and Android.

React native and JavaScript.

React Native uses JavaScript to design cross-platform applications. JavaScript is currently one of the most popular and widely used web programming languages. This language is used with React and many Java frameworks. In this way, a person who is proficient in JavaScript programming, with just a little time to learn React Native technology, will be able to easily design and produce an application for iOS and Android.

Flutter and Darts

Dart, unveiled by Google in 2011, is one of the few programming languages ​​rarely used by programmers. The syntax of darts is such that learning it is easy and fast for JavaScript programmers. Therefore, learning darts and then using Flutter is an easy and feasible topic for programmers who intend to use this technology to produce their desired applications.

Conclusion

If we compare React Native and Flutter only from the point of view of programming language, we must say that using native is much easier and more acceptable for programmers fluent in JavaScript. Although learning to use Flutter is not a difficult and complex subject, in this index, the superiority of React Native over Flutter is evident only from using a more well-known programming language among users.

2- Technical structure

It is important to be aware of its technical structure when choosing a suitable framework for developing cross-platform applications. This way, we can choose the best framework whose structure is according to our needs and the type of project we want.

React native – FLUX stream.

The overall structure of react native is based on the JavaScript bridge. In this way, JavaScript code is converted to native code at runtime. React native uses the Facebook flux structure in its structure. For more information on this topic, you should read the articles and resources published in the introduction of Flux. Still, in general, it should be said that the structure of react native is such that JavaScript code by JavaScript bridges to native modules intended for iOS And Android converts.

Flutter – Skia

We know that Flutter uses the Dart framework and thus has unique internal components in its core structure that convert the program written by its user to native modules without the need for bridges.

The start framework structure provides the user with various frameworks, including Material Design and Cupertino, as a package. The Dart framework uses the C ++ Skia engine, which has all the protocols, ballads, and channels.

Conclusion

Given what I have said, if we want to compare react native and Flutter only in terms of technical structure, we must say that Flutter, by default, has many components in its structure, and designing an application by it does not need to use bridges. It does not have to be into readable and executable majuses on iOS and Android. In fact, from this perspective, react native has performed and appeared to be slightly weaker than flutter.

3- Compare react native and Flutter in terms of installation method

According to the previous statement about the emergence of react native and Flutter to save developers time and energy, it is obvious that our chosen one should have the easiest installation method to achieve this increase in speed and prevent energy loss.

React native – NPM

React Native can be installed by NPM or Node Package Manager. Developers and programmers familiar with JavaScript can easily install React Native. Other programmers need to be trained in how to work with NPM. NPM can install packages locally or globally. Developers need to know the exact location of the binary.

Flutter – Download binaries from resources

To install Flutter, you can download the appropriate version for one of the platforms from the GitHub binary.

Conclusion

Although both of these technologies lack easy installation and one step, as it turned out, Flutter has a few extra steps to install compared to react native. So, if we just want to compare these two options based on how they are installed, I must say that react native is easier to install.

4- Launching and receiving approvals

In fact, after installing these programs, receiving approvals and activating them is a category that requires time and energy. So, if we still aim to use these programs to save time and prevent energy waste, we must see which has brought us more speed and ease of action.

React Native

React Native has all the necessary approvals to activate and transfer the project to readable iOS and Android modules. A reputable source should provide a list of them.

Flutter

It has a tool called CLI or Dr. Flutter that lets you know and get any information or confirmation you need. When Dr. Flutter is happy, the operation works properly, and your project does not need further approval.

Conclusion

In this comparison, it is clear that Flutter helps the user receive approvals much better than React Native by providing a smart and up-to-date assistant.

5- Compare react native and Flutter in terms of UI and API development components

Our selected framework must have the necessary API to access the native module and perform the desired operation without any damage or defects.

React native – fewer components.

The core of the react native framework provides output from the UI and device or device access to the API. To access most native modules, react native has to do things based on third-party libraries. React native relies heavily on third-party libraries.

Flutter – Rich in components

Flutter has many features, including UI output, device API access, navigation, testing, full management, and library retrieval. Therefore, there is no need for third-party libraries in Flutter. Flutter also has widgets for UI output and API access in Material Design and Cupertino.

Conclusion

In this comparison, flutter has many more advantages than react native.

6- Developer efficiency

A programmer must use a framework that is compatible with his knowledge and skills and generally causes him the least concern in order to design and produce the desired application with the least amount of time and energy.

React Native

If a developer is proficient in JavaScript, he or she can easily apply his or her skills and knowledge to cross-platform application development frameworks. Among these frameworks, React Native is one option that greatly avoids wasting programmer time and energy. IDE support, the ability to use any text editor, and the like are some of the benefits of using React Native for a programmer fluent in JavaScript.

Flutter

To work with Flutter and enjoy the benefits not found in React Native or other frameworks, the user must spend some time learning the space and its commands. Then, the task becomes easier, and all the simple things will happen. Went. However, Dart is not a common programming language and is not supported in many editors.

Conclusion

React native has become more mature and appropriate regarding up-to-date, common programming languages and related tools.

7- Compare react native and Flutter in terms of support forums

The world of technology is such that people can not access all the knowledge contained in it through educational classes and videos alone, and suffice to learn theoretically and presented by professors. Rather, it is necessary for individuals and activists in this field to be in constant contact with each other and to learn new tips and experiences from each other. Therefore, in all branches of technology, there are usually online support forums and blogs through which the activists of that branch share their questions and experiences.

React Native

In 2015, React Native came and flourished among the people. In the same year, an association was formed on GitHub for this framework, which included many conferences and online and face-to-face visits. Reactive meetings and conferences are taking place in many cities and countries today.

Flutter

It took a while for Flutter to be released, but when Google unveiled it at the Google I / O conference, it quickly became popular. Hence, the Flutter backup community is rapidly developing and operating. However, many users still have no resources to answer and fix the problem.

Conclusion

Obviously, there are many resources and people to help a React Native user solve potential problems, but these features still need room for growth and optimization for the Flutter user.

8- Test support

We know very well that writing tests and tests are the best way to discover possible flaws in the written code. There is always a framework for testing each technology. It allows users to test items such as the UI and other important points of the designed application.

React Native

Because JavaScript is the native language, the tools in JavaScript can also be used to test code. Tools like Jest can be used to test snapshots. When it comes to testing things like the UI, React Native uses third-party libraries like Appium and Detox.

Flutter

Flutter offers many testing possibilities. It provides widgets and test programs for various applications. A list of these widgets can be obtained from reputable sites in this field.

Conclusion

It is clear that in this comparison, Flutter is more successful than React Native because it has provided much more complete possibilities for testing the designed application with its users.

9- Comparison of react native and Flutter in terms of manufacturing and publishing automation

Publishing an app designed separately for iOS and Android alone is a troublesome and challenging project for developers. The code required for this part of the project is very complex, and it involves designing and publishing an application.

React Native

For react native, there are no automatic steps for releasing apps on iOS and Android. There is also a manual process for deploying an application designed in Xcode, for which we have already given instructions.

Flutter

According to Flutter documents, there are rich steps that automatically perform some sort of application release operation. There are strong commands for releasing multiple apps designed for both iOS and Android systems.

Conclusion

The application release process for Flutter is much more professional and user-friendly than react native.

10- CI/CD support

CI, or Continuous Integration, and CD, or Continuous Delivery, are essential for any application. They allow it to receive continuous feedback and subsequently prevent the publication of faulty code.

React Native

React Native does not have an official document for launching CI/CD. Of course, there are articles and content about CI/CD in React Native. There is also an article explaining this with NeverCode.

Flutter

It has a Continuous Integration and Testing section that links external resources. However, flutter allows us to set up CI/CD as easily as possible.

Conclusion

This index reveals that Flutter is easier to set up CI/CD than React Native because React Native does not follow a specific mechanism.

total resulting

Although both React Native and Flutter frameworks can be as effective and efficient as their users need them to be, Flutter appears to be much more efficient and successful than React Native. In other words, although Flutter does not have a common programming language, it may be chosen and used by many developers because it has many special advantages.
