What is Flutter?

Flutter is a reactive cross-platform mobile development platform developed by Google that uses the Google Dart language. Flutter was first announced at the launch of the Dart Summit in 2015. Three years later, Google released its first version, Flutter 1.0, at the Flutter Live event on December 5, 2018. It is used to enhance apps for Android, iOS, Windows, Mac, Linux, Google Fuchsia, and the web using a single source code. With strong Google support, Flutter can quickly integrate with other cross-platform options like React Natives. The Flutter theme is a redesign process that includes a wide variety of widgets designed to be used. Flutter applications are compiled using the C / C ++ mobile library, which is similar to machine language and improves field performance. Let’s look at some of the pros and cons of Flutter vs React Native:

Flutter pros

Some of the advantages of cross-platform mobile app development using Flutter include:

  • Hot reload: The main advantage of using Flutter is that you can make your changes almost instantly. A quick reinstallation allows developers to make changes to their native code without having to restart the application for the changes to take effect.
  • Cross-platform development from one codebase:  With Flutter, you can support iOS and Android platforms by creating a single source code. The same database can be used for other Flutter-enabled platforms, including the web. Flutter also has widgets and layouts, giving you the option to build the same app on two platforms. Or change it if necessary.
  • Cut down on debugging time: Using the same application on both platforms and having the same database means that you only have to make a debug once instead of debugging for every different platform.
  • Fast Fluid UI: The flutter app offers a fast and fluid user interface thanks to its Skia graphics library. With libraries, the UI is reused whenever the concept changes. With the help of the GPU, Flutter UI offers an ever faster experience.
  • Great app design: Flutter has its custom widget and does not use any elements of the native system. Flutter also has a simple yet user-friendly user interface. It looks good, and it gives Flutter a huge advantage over react native.
  • Same app UI, even on older devices: Being independent of the basics and being on the right platform works for both new and old devices. This app is similar to older iOS / Android devices and newer versions.
  • Perfect for MVPs: An important factor in looking for cross-platform development options is how you can create your application quickly and easily. There is a lot of need to build an MVP (Minimum Viable Product) for an application, and Flutter is the best option to get it done.
  • Flutter community and support: Traditionally, Flutter was a newer option than react native, so community support was always at a disadvantage.  However, due to its popularity among the community, Flutter has surpassed all the fame and community support when compared to React native.  Flutter currently has more than 102,000 stars on Github, while React Native has more than 92,200 stars.  Google also continues to significantly support Flutter and its developments.
  • Open source and completely free: Flutter is completely free, unlike other options such as the use of an application builder and a non-code-based solution that meets the needs of cross-development.

Flutter Cons

The popular Flutter is growing in popularity among current platform development products, but it is not necessarily perfect.

  • Dart language: Dart itself is a very strong programming language, but it was only developed with Flutter. To improve your application with Flutter, you need to learn the details on how to use and write the Dart script. This installation barrier can be discouraging for many users who can configure standard languages ​​such as JavaScript, as in the case of React Native.
  • Libraries compared to native development: Google is strongly supporting Flutter and its community, but it’s relatively new. Libraries have come a long way but there is still some functionality that would be available, with better implementation in native development.
  • Apps in the wild: Flutter became famous in popularity in development circles. Not many apps adopt it. The lack of examples of complex applications running Flutter in the field can be problematic, but this can change quickly.
  • App sizes: Flutter has been researching this issue, and they have their guide to reduce file size. But flutter applications tend to be larger than native applications.

What is React Native?

React Native is a cross-platform native mobile application development framework created by Facebook based on its React JavaScript library. React Native mainly uses JavaScript, JSX is an extension of JavaScript, ES6 (ECMAScript6) is the main update of Java script, including dozens of new features, and React JS, a JavaScript library for building user interfaces. React Native allows you to build a mobile application using React Native components and then compile it into a native application that is almost the same as an application written with native tools.

Let’s look at some of the pros and cons of React Native vs Flutter:

React Native Pros

  • Reusable Code: Develop an application and export it on multiple platforms from one codebase.
  • App Stores:  Publish your application on the app store of the respective platform.
  • Performance: React Native compiles your application into a native application, almost the same as an application created with native tools, making it faster than a hybrid application that has to run code in platform-specific web components.
  • Native UI Components: React Native allows you to create views using React Native UI components, which are compiled into platform-specific UI components, unlike other cross-platform tools that use HTML markup. By providing ready-made components, you save a lot of time compared to writing everything from scratch.
  • Hot Reloading: A feature in React Native allows code changes to take effect immediately in iOS and Android applications so that you can visualize the changes immediately.
  • Testing: Debugging React Native applications is quite easy because it publishes local applications and can be tested on physical devices using tools such as Expo. This is a free and open-source toolchain built around React Native without the need for Xcode or Open them in AndroidStudio
  • Native Code: Unlike most other cross-platform development tools, ReactNative allows you to further modify the published native application individually. It allows you to choose or even combine ReactNative code with native code, whether it is Swift, Objective-C or Java. This is great if you want to use platform-specific code to implement separate visualization components for different platforms.
  • Reliability: React Native was created by Facebook, and many of the top mobile applications in the world use React Native, including Facebook, Instagram, Sound Cloud and Skype. So needless to say, it is very stable and reliable.
  • Free and open-source: React Native is completely free to use, instead of other options, such as using an application builder or a no-code solution for cross-development needs.

React Native Cons

Although React Native is currently one of the best cross-platform development tools, it is certainly not perfect.

  • New Technologies: Learning JSX and ECMAScript is not so easy, and may take more time than other familiar technologies (such as HTML and CSS).
  • Native UI Components: Although UI components are one of the greatest advantages of React Native, considering that it is still a fairly new cross-platform development framework, only a few off-the-shelf components are currently available. This will change over time.
  • Native Code: In some cases, you may have to write native or platform-specific code in a mobile application, especially if you need to access device hardware, such as a camera or GPS, which may defeat the purpose of cross-platform development and may Think ReactNative is useless for smaller teams.
  • Almost-Perfect Performance:  Although React Native is superior in performance to most other cross-platform development frameworks, it is still inferior to developing native applications using platform-specific tools and languages.

Who wins?

Every application and every mobile team is different. In the market, there will be room for Flutter and React Native. Traditionally, as React Native is built and used much more in large applications, it usually starts. But this is not the case now; there are very reasonable reasons and chatter. Mainly a great UI, it is supported by a rapidly growing community and library.
