Flutter and React Native advantages and disadvantages

Though Flutter and React Native are two of the best cross-platform application development frameworks, but also the best multi-platform framework out here:

Advantages of Technologies

  • Pros of Flutter:

Performance: JS is faster than Dart, but apps created with Flutter are much faster and high performing for Android and iOS than React Native.

Hot-reloading: To enable experimentation, as well as rapid bug-fixing, to reflect changes immediately, without changing the overall functionality of the app.

Rich Widgets: Flutter with platform-specific SDK uses the proprietary visual, structural platform for feature-rich widgets for Cupertino (IOS) and material design (Android)

Easy integration: Flutter-based apps are very smooth in their performance which makes for great UX, with interaction with Java for android and Swift, C for iOS

  • Pros of React Native

Performance: Both Flutter and React native support superior and high-quality cross-platform application development for Android, and iOS

Native rendering: APIs are rendered natively without requiring HTML or CSS markup on the host platform.

Development Time: React Native provides shorter app development time for cross-platform application development

React’s benefits: Help developers save time learning new languages by leveraging React’s ecosystem and UI libraries.

Hot-reloading: It allows hot reloading to add new codes directly into a live application. Without hampering the application's natural state.

Disadvantages of Technologies

  • Cons of Flutter:

Limitations: Flutter SDK includes advanced libraries and tools, but develops drawbacks with time and in the use of third-party APIs.

Development: Flutter-based applications are fast to create and efficient, but there is room for improvement.

User interface: The plugins need to be fixed for better graphics visualizations, and to be improved for a better user interface.

Compatibility to other operating platforms: Dart is not the popular language, and apps cannot be developed for tvOS, Android Auto, CarPlay, or watchOS.

Regular Updates: There is no direct application updating without passing through the standard release process.

  • Cons of React Native

User Interface: Native rendering of APIs may not support certain native UI elements, which may make the UI look a little off.

Updates: Many APIs and plugins are outdated and don’t get regular updates

Performance: Has no parallel threading and multiprocessing support, and is even criticized for slow performing apps

Debugging: Developers may face problems with package compatibility or debugging tools.

Lacks the Security- Because the framework utilizes JavaScript, there is a gap in the security protection.

Flutter vs React Native Popularity

Flutter is only a few years old and has gained much popularity among developers loyal to Google products. As Google is behind Flutter, it has gained quite a bit of attention too since the e-commerce giant Alibaba recently adopted flutter. Flutter ranks higher with 75.4% among most loved frameworks.

  • The popularity of React Native

The concept of React Native has been around for several years, and due to the success of React, many people have already worked on React. Most react developers prefer React Native. However, 62.5% of respondents chose React Native among the most popular frameworks.

Winner: Flutter

It would be somewhat debatable, as respective communities of Flutter and RN divided over which is popular.

Flutter vs React Native Performance Comparison

  • How does Flutter stand out in terms of performance?

Dart code is compiled to native machine code, hence eliminating the JavaScript bridge to provide availability of default native components. The Skia graphics library is also used in Flutter to improve performance by redrawing the UI each time an application view changes and reducing the number of frames. Flutter can render at 60 FPS very efficiently and perform better than React Native.

  • How does React Native stand out in terms of performance?

React Native has a lower performance compared to Flutter, for the obvious reasons why Flutter is the better performant. React Native uses JavaScript to interact with Native modules, which are more time-consuming programs, making the application shutter. Although, the app’s performance can be improved using third-party libraries and open-source command-line tools to minify and optimize Java code for better app performance.

Application Architecture / Technical Architecture

Application developers can take advantage of several advantages offered by Flutter and React Native. Here are some details.

  • What Architecture does Flutter support?

Flutter offers a layered BLoC architecture introduced in 2019 by Google. Business logic components or BLoC is a layered architecture that is based on separate components. Just beyond rendering layers, Flutter BLoC contains a separate presentation layer and business logic to be easily shared between different dart apps making your code fast, easy to test, and reusable. Which prevents multiple rebuilds and makes it easy for developers providing flutter app development services.

  • What Architecture Does React Native support?

React Native architecture is based on JavaScript, where Java thread is the core element of its architecture. That requires Javascript to communicate with Native thread. Its platform and Native API through the bridge as per the functionality. In iOS, it uses JScore separately to run all codes, whereas it bundles the JavaScriptCore in Android. Which could increase the development time, the application size, as well as hamper the overall application performance.

Suitability for building complex apps- Flutter vs React Native

  • Is Flutter suitable for building complex apps?

Flutter is fast even if it has been pushed beyond limits. Usually, complex application development in Flutter is done in phases. It is important to build two different prototypes (iOS and Android) with Flutter and then analyze your results in the market. Then, you can invest more and take your idea to the next level of complexity.

  • React Native suitable for building complex apps?

React Native allows users to build a complex app when they involve Native app development. But almost every time it requires you to write bridges and have to use native APIs. At any level of complex app development in React Native involve native development expertise along with JavaScript. Which makes it time-consuming, and might hamper the app’s performance as well.

CodeFencer Views

Flutter is preferred for building complex applications despite both Flutter and React Native providing documentation, guides, open-source projects, third-party plugins, etc.

Ease of Testing Flutter and React Native

  • How easier is it to test a Flutter app?

Flutter comes with rich support for application testing in Flutter, from unit and widget tests up to integration tests. Flutter allows integrating and running automated tests to ensure a greater user experience. It provides detailed documentation for CI/CD setup and support for continuous testing and to build and deploy iOS and Android applications. The dart language functioning advantage, testing applications in Flutter can be done with numerous features at all levels such as unit, widget, and integration level.

  • How easier is it to test a React Native app?

React Native framework, does not support testing and CI/CD out of the box or specific tools and features that support UI level testing or in-built integration testing. Mostly due to the dependence on third-party libraries for app building and release automation. Application testing in React Native framework also commences with the use of third-party application testing tools like Appium and Detox. In most cases, React Native suggests developers define a manual process of deploying the app with third-party tools.


CodeFencers views

Flutter has an edge over RN for easy application testing. But despite the many limitations, React Native is pretty useful with advanced third-party tools.

Community around Flutter and React Native

Both Flutter and React Native is popular among the developer community and have strong open community engagement spaces. Where developers around the world can share their experience and get solutions.

In terms of community engagement, let's compare the two frameworks.

  • How big is the community around Flutter?

Flutter is gaining much popularity among the developer community that is open to all. There are a lot of exciting things happening in highlights of Flutter version 2.0 release with Dart 2,12 and more. Flutter SDK is a rapidly growing and vibrant community with 700+ professionals contributing with 14k+ live projects supporting the Flutter online developer community and Flutter ecosystem with exclusive resources since its launch in 2017.

Some popular platforms for connecting with the global Flutter community:

  • How big is the community around React Native?

React Native is supported by a strong open community of developers contributing to its development since the launch of React Native in 2015. The JavaScript-based framework has become one of the most popular open-source platforms on GitHub. The core of React Native is worked on full-time by Facebook's React Native team. But there are more than 3000+ developers around the world using React Native who make key contributions and fix things with 20k+ live projects.

Where you can find React Native developers, projects, conferences, and live events:

Modularity comparison in Flutter vs React Native

Application project growth and increased complexity make it hard to keep your code and project structure maintainable and reusable. Modular provides a bunch of solutions to deal with such problems. The best suited for both Flutter and React native.

Let’s check whether Flutter and React Native compare in terms of Modularity.

  • Does Flutter support modularity?

Flutter offers a public package system that allows the division of project codes into different modules and better accessibility for diverse teams. The plug-in feature allows you to create different modules and add or change codebases easily.

  • Does React Native support modularity?

React Native may offer less modularity support than Flutter. Developers of the Android, iOS and Reactjs platforms may find it hard to communicate. The code fragmentation problem in React Native may be problematic for teams without expertise.

Code Maintainability

It relates to how easy it is to make changes to code correctly. These best practices require organization-wide coordination, on finding, reusing, and changing code from other teams while managing dependencies.

  • How convenient is it to maintain code in Flutter apps?

Maintaining a Flutter application is easy. Developers are better able to detect problems, find external tools, and support third-party libraries when code is clear. Hot Reloading eliminates problems immediately when it is in full effect, as well. Quality updates and making immediate changes are more convenient with React Native than with hot reloading.

  • How convenient is it to maintain code in React Native apps?

Probably the biggest challenge with React Native is upgrading and debugging. By forking a framework's code to suit your application, you interfere with its logic and slow down its development. Moreover, most of the native components may be dependent on a third-party library. The issue is that these libraries are often outdated and cannot be maintained properly due to the issues that come along with them.

CodeFencers’ Advice

Even though React Native is one of the largest communities and has official support, there are challenges to maintaining the language for your application. Flutter is easier to maintain than React Native.

Comparing user experience in Flutter vs React Native

  • Flutter’s ability to give the best user experience

Flutter have simple simple tools, elements, and customized widgets for a great user experience. Dart has a robust junk collection feature that helps create UI frames for temporary object code. As a result of Dart's pointer bump feature, this avoids UI clutter, junk, and shutter lag during development.

  • React Native’s ability to give the best user experience

It's tough for React Native to keep up with the constant changes in native platform requirements as Material Design in Android and Style Design in iOS transform every day. Additionally, ready-made React Native UI kits such as React Virgin, make it even more difficult to create consistent designs across platforms.

CodeFencers’ Advice

An engaging user experience also allows you to define online journeys that are most conducive to your business's success.

Application size

  • Size of the application in Flutter

In Flutter, a simple hello world app weighed 7.5 MB. Flutter's virtual machine and C/C++ engine determine how big the app will be. To avoid size concerns, Flutter can self-contain all codes and assets. The use of a special tag, such as –split-debug-info, can help reduce the size of the code.

  • Size of the application in React Native

Hello, World with React Native had an initial size of 7 MB, and when native dependencies were added, the size increased to 13.4 MB. In contrast to Flutter, React Native can iterate faster and at a smaller size.


CodeFencers Advice

The choice of a mobile framework can greatly affect the size of the application code. For a large project, the application size should dominate the framework size. Smaller is better here.

Learning curve

  • How good is the learning curve of Flutter for developers?

Another reason for Flutter's rapid growth among developers is its simplicity. It offers seamless detailed documentation and a large number of examples that make learning easy. Creating code with Dart might seem unusual at first, but that's what makes it easier to develop with Flutter. This framework can be learned with some basic understanding of Android or iOS development. is very important for developers who want to learn a new platform, a set of tools, or a language.

  • How good is the learning curve of React Native for developers?

Those who have built applications using JavaScript should have no trouble learning React Native. However, web development is different from mobile app development, so mobile developers may find it hard to learn and implement the framework. Since its release, React Native has released various libraries, extensive documentation, and tutorials, which have improved the learning curve.

CodeFencers’ Advice

There are different learning curves for Flutter and React Native, so it will be difficult to underline which is better flutter or react native. And how feasible is it to learn Flutter and React Native?

Comparison for team size in Flutter vs React Native

  • How big should be the required team size for Flutter?

Flutter framework has a simple learning curve that not only makes it easier for developers to write code, but it also makes it easier for new developers to understand that code. Big players like Alibaba, BMW, Watermaniac, and PostMuse, among others, have built their apps using Flutter with as few as 5 developers. Because Flutter and Dart training is inexpensive, even a newbie developer can be trained quickly, and you won't have to hire numerous experienced engineers.Which ultimately down the need of a different developer for every different project.

  • How big should be the required team size for React Native?

You may require roughly 5 to 10 developers to build a React Native application. The team consists of people with different skill-sets and experiences, with at least two React Native professionals on hand to guide them through the development process. Because code maintenance across several platforms is critical to the success of a React Native application, you should work with developers with comprehensive technical experience.

CodeFencers’ Advice

Regardless of the benefits and drawbacks of Flutter and React Native, determining the team size before starting development is critical. This will allow you to budget and make well-informed decisions based on the Mobile app development company or hiring cost of mobile app developers.
