Flutter Vs. React Native- Which Framework is Better?

With growing business applications, every organization strives to build mobile applications to stay competitive in its niche. Flutter is a free and open-source framework offered by Google that allows businesses to develop cross-platform mobile applications. React native is a free and open-source JavaScript framework that enables the development of cross-platform applications for iOS, Android, Windows, and MacOS.

Flutter and React Native are vital cross-platform frameworks that share code across different platforms utilizing native widgets to deliver a customizable and responsive UI. These frameworks are native and offer advantages over traditional native application development since they share a vast proportion of the codebase across platforms.

Both these platforms are efficient in building cross-platform mobile applications; however, the right decision to choose one narrows down to business requirements. Here are a few noteworthy characteristics of Flutter and React Native.

Flutter

• Development and Installation

A Flutter application houses a widget. Flutter offers multiple ready-to-use widgets that implement material design concepts. Unfortunately, two kinds of widgets- stateless and stateful- are not adaptive. Due to this, businesses will have to make platform-specific adaptations manually.

Getting started with Flutter is pretty straightforward. Developers must download the package, unzip and create an environment variable that caters to a folder within the unzipped folder. They might also need to download the Android Studio to set up an emulator to avoid using the phone.

Moreover, it supports the Hot Reload feature, enabling developers to rerun the application with the amendments during development. Android Studio, IntelliJ Idea, and Visual Studio Code currently support Flutter.

• UI Components and Ecosystem

This framework comes with multiple UI rendering components, navigation, libraries, and Application Programming Interface (API) access helping developers to develop top-notch applications. Numerous widgets also make businesses build UI on Android and iOS devices. Flutter has a bunch of mobile development core packages available publicly. Its ecosystem offers sufficient momentum due to an active and dedicated community.

• Performance and Documentation

Flutter’s application utilizes the arm C/C++ library to compile, making it closer to a machine language and providing a powerful native performance. Moreover, Dart is high-performing, giving Flutter a smooth upper hand of 60 frames-per-second speed.

It has good documentation with an active sharing community. Simultaneously, Flutter’s team is helpful, making it relatively easy for developers to utilize the platform. Developers must understand that though the documentation is comprehensive, it might pose challenges when the user does not have programming experience.

• Architecture

Flutter makes developers skeptical about the architecture to implement for the application since it is relatively new. One of the famous architectures is the Business Logic Component (BLoC) architecture. Google’s depiction of the architecture states that omission of the business logic from the presentation layer and placed in the business logic components.

Moreover, the BLoC pattern mostly relies on streams and Reactive Dart (RxDart). Developers might feel Redux/Flux is more comfortable, which is true with a few Flutter packages. These will serve well if developers want to create small applications and are new to Flutter.

• Efficiencies and Pitfalls

It allows developers to build applications using the same codebase quickly. The “hot reload” feature makes the experimentation and bug resolution seamless. Its layered architecture maximizes customization control preventing errors.

On the contrary, it is s young framework with redundant issues that are hard to rectify. Applications take more time to download and take up more storage space. More importantly, it offers good libraries and support but is less productive than native development.

React Native

• Development and Installation

React native utilizes components; developers must use the features offered by the react-native library for mobile development instead of web components like H1 and Div. It uses a virtual DOM to communicate with native UI elements. Moreover, it does not have many widgets; it includes adaptive components. To run React Native, developers must install the create-react-native-app package with npm, allowing them to create a new React Native application.

One crucial factor in the development of React Native is its provision of “Expo integration.” This provision lets developers run the code on their mobile devices without wiring it up. Interestingly, they will need to scan a QR code that appears on the console.

• UI Components and Ecosystem

React Native provides UI rendering that relies on third-party libraries for accessing native modules. Some developers believe that it relies more heavily on these third parties. The platform has a hot reload function, like Flutter. It has more packages while the framework is mature and stable.

• Performance and Documentation

The entire approach compilation is not to C/C++ or a native language; instead, it is compiled to their native equivalents along with a JS code running in a separate thread and simultaneously communicating with native modules. Initializing Javascript, unfortunately, and requiring the modules is a difficult task.

React Native performs better than hybrid alternatives but falls short in performance. The documentation is sufficient and more user-friendly since it includes prop explanations, guides, and popular cross-platform development topics like installing native modules.

• Architecture

The two main patterns in creating React/React to native applications- are Flux and Redux.

These frameworks are about one-way data flow and store the application’s state in one central place- Store. These can make the application components stateless while allowing developers to utilize content API- a new React feature for state management.

• Efficiencies and Pitfalls

It has extensive base packages due to the widely popular JavaScript language. Developers can simultaneously leverage one codebase feature to develop an application for numerous devices. It encourages developer freedom of choice, allowing code reuse and saving costs. Moreover, it has an active and vast community with ample documentation for React developers to learn.

On the contrary, it still requires native developers and has debugging issues. It has a fragile UI, and applications are more significant than the native ones.

React Native and Flutter have robust characteristics and adequate documentation. They have features like live refreshing or building graphic UIs with adaptable software. The idea is to fill in the gaps between the iOS and Android platforms. The bottom line is that both platforms serve different purposes; hence, businesses must consider the requirements before committing to one platform.
