Flutter Vs. React Native – What is the Best for Mobile App Development in 2021

Looking to go responsive? But feeling confused over which technology should you choose to get an application developed quickly at a reasonable cost? If you answered yes to both these questions, you have two options: Flutter and React Native. Again, you must be wondering which can be the best one for cross-platform application development? Let us have a detailed look at both these technologies to find out the best one:

What is Flutter?

Flutter is a popular open-source framework. It working using Dart language created by Google. Flutter is an enhanced UI toolkit which is used to create cross-platform apps using only one codebase. With Flutter, Toronto App Development Companies can develop flexible and expressive UI that deliver native performance.

Pros of Flutter

  • Rich Widgets
  • Hot-reloading
  • Quick shipping
  • Seamless Integration
  • Codesharing

Cons of Flutter

  • Lesser Operating Platforms
  • Problems in rendering plugins timely
  • Cannot push updates instantly

What is React Native?

Running on JavaScript, React Native is another open-source framework. It mainly focuses on native rendering of apps compatible with iOS and android. RN is written combining JavaScript and XML- Esquemarkup.

Pros of React Native

Performance

Debugging

Native Rendering

Rich Ecosystem and excellent UI libraries

Hot Reloading

Cons of React Native

  • Outdated third-part libraries
  • UI is a bit off
  • No support for multi-processing and parallel threading
  • Inconvenient to edit chrome debugger

Flutter Vs. React Native – What is the Best for Mobile App Development in 2021

Both these frameworks have the same niche when it comes to application development . They share the same features as well. Both of them are great to create a cross-platform MVP having the possibility to re-use the code later and extend it using a free community-provided or official add-on. They are also known to reduce project expenditure and time-to-market when building for various platforms. But how do both of them still differ?

Learning Curve

React Native is better than Flutter because it uses JavaScript, which is the most famous programming language around the world. But, JavaScript is not the most exciting and simplest programming language. Most developers in an app development company Canada enjoy working with languages that are convenient and fun to work with. So, which is simpler to learn- React Native or Flutter? From the perspective of a developer, Flutter is simpler to learn compared to Flutter. Flutter is developer-friendly. But React Native is not. It is mainly because React Native uses JavaScript which is not the most friendly programming language. There are classes within classes along with all kinds of other quirks.

Performance

The architecture of React Native needs a bridge that allows interaction between native UI components, device-specific elements, and JavaScript. Due to this bridge-based communication RN is slower than Flutter. When it comes to Flutter, no bridge is there. Rather, Flutter’s Skia– the core graphic machine – complies the user interface to native codes when the users interact with the application.

Maturity

A technology’s maturity is reflected in positive and wide adoption and long-term support. RN has lots of high-class third-part libraries. Moreover, it has been included in many tech stacks of top brands. Though, Flutter is also catching up quickly. It can be concluded that both these technologies are maturing to be securely used in production.

Hot-reload

It is a convenient feature that lets developers reload the application and look up for changes within the  UI. The counterpart of React Native is Fast Refresh that works same as Hot Reload of Flutter. The drawback of both versions of this feature is that  superior changes cannot be hot reloaded in the code. Complex changes need app recompilation.

Programming Language

Flutter uses Dart language which is similar to Java and Kotlin. It is simpler to learn for developers who know native mobile development. However, JavaScript is lesser intuitive and harder to master.

Code Maintenance

React Native has one of the largest official support and communities, still there are issues that you may face while maintaining this language. Flutter, on the other hand, can be maintained more conveniently.

Cross-Platform Capacity

Using Flutter, you may write applications that work on Windows, Linux, macOS, embedded systems, web, iOS, and Android. Flutter 2 offers a promise of true cross-platform development capabilities, with this SDK allowing developers to share codes between every compatible platform.

React Native lets developers create apps for Android and iOS and the web through React. Desktop apps can also be written in RN both for Windows and macOS.

Debugging

Debugging can be a little problematic in React Native, particularly when a particular error or exception originates in thee native segment of the application. On the native end, bugs can come either from third-party libraries or React Native. However, a new tool is coming to help for debugging in React Native, that is Flipper.

Debugging in Flutter is simpler with the help of tools that easily support development in Visual Studio and Android Studio. OEM Debugger and DevTools help devs find and understand errors.

Conclusion

React Native is an excellent framework to create cross-platform and simple native applications. Flutter is good at building MVP and multiple iterations applications. To help further, here is a checklist that must help you select which of the technologies should be best for you.

Go with Flutter, if:

  • You have a quick delivery timeline and tight budget.
  • Your idea doesn’t need complete native functionality.
  • You want to customize UI with less testing and widgets.
  • You want reduction in development cost by writing only one codebase with support for multi-platforms.
  • You are looking to write faster codes and deploy them quickly in the market.

Go With React Native, If:

  • You have sufficient money and time to invest into a project.
  • You intend to build an application with a responsive UI and asynchronous build.
  • You are looking to scale your current app with cross-platform module.
  • You want possibilities to build outstanding shared APIs.
  • Your need is to create lightweight native apps.
