Flutter Vs React Native


Share

Installation

React Native - NPM
Flutter - Binary Download from Source


The installation method should be straightforward without having too many complicated steps so that it could be easily learned by developers that are just starting with it.



Programming Language

The key benefit to using a cross-platform mobile app development technology is the ability to use a single programming language to develop apps for both iOS and Android.

React Native - JavaScript
Flutter - Dart

As JavaScript is widely used by most web developers, it's easy to adopt the React Native framework. Dart also has a great feature set but it's rarely used and less known in the developer community. Considering this, it's clear that React Native wins the point in the programming language category.



Technical Architecture

When choosing a cross-platform mobile app development framework, it's essential to consider its technical architecture. By knowing the internals of the framework, we can make an informed decision and choose the one that is better for our project.

React Native - Flux
Flutter - Skia

Flutter engine has most of the native components in the framework itself and it doesn't always need a bridge to communicate with the native components. React Native, however, uses the JavaScript bridge to communicate with native modules, which results in poor performance.



Setup and Project Configuration

The process of setting up the developer machine to use the new framework takes time. It requires lots of configuration of software installations. The technology should have proper documentation to get users up and running. From the comparison above, it's clear thar Flutter offers better documentation and CLI support for setup and configuration



UI Component and Development API

React Native - Less Components
Flutter - Rich in Components


Flutter is rich in development APIs and UI components while React Native is too much dependent on third-party libraries.



Developer Productivity

Developer productivity is the key to building apps faster. In this regard, it's very important to be able to focus on app development without any kind of wait or distraction. Being a mature framework, React Native has great developer support in terms of IDEs and language features. Flutter is fairly new at this point but will catch up very soon as the community around Flutter grows.



Community Support

The React Native community and resources have grown in size since the framework was launched. Flutter is still fairly new, although community support is growning repidly.



Testing Support

The React Native community has no official support for integration and UI level testing. While Flutter has great documentation and a rich set of testing features.



Build & Release Automation Support

Flutter has a great build automation tooling and can be used to deploy apps from the command line. React Native apps lack support for the CLI tools that are officially supported for build automation.



DevOps and CI/CD Support

Flutter apps are easy and painless to set up on CI/CD services by using its strong CLI tools. React Native doesn't provide any official instructions for CI/CD practices.



Conclusion

React Native and Flutter both have their pros and cons, but Flutter came out as the winner in this match. Some of the industry experts have predicted that Flutter is the future of mobile app development. Considering the comparison above, it's clear that Flutter has entered the cross-platform mobile development race very strongly. Let's not predict the future but wait and watch!
