Flutter Components vs React Native Components

Picture this scenario on a construction site, where the construction workers are stacking the bricks on top of each other. Layered with cement, these bricks create the foundation for a stable structure.

Components are the foundation of your applications. When you focus your energies on creating a defined component, you spend less time on actual development.

Moreover, you can reuse components throughout the application, which will help accelerate development. As more of us are opting for cross-platform development, reusable components can enable faster and more reliable development.

When you say cross-platform application development, both React Native and Flutter frameworks top the developer’s mind. You can choose to build components with either framework.

We will discuss the component development using both frameworks in this article. It will help us realize the ideal framework for component development and imagining.

Overview of Flutter Components

Flutter uses a widget-based architecture to develop the interface structure and design. Widgets are easy to add, reuse and include in the application interface. We will look at the different components of the Flutter design that can enable better design and app solutions.

#1. The Hot Reload Feature

When you are working with the Flutter framework, the hot reload feature can offer great respite to the developers. It can help develop Flutter UI components without impacting the live code. You can even make changes within the reused components, and ensure the changes are updated across all of them.

This would enhance the overall development and debugging abilities of the mobile app developer. Moreover, it can help accelerate the deployment of the application.

#2. Widget-driven Architecture

The best part about working with Flutter components is that it offers a widget-based architecture. This can help build a lightweight and fast application that is built using self-contained blocks. These blocks are the base structures for the application.

You can create two different widgets- stateless and stateful widgets.

When you use stateless widgets, you are using UI elements that may not change with time. however, if there are widgets that can change with time, you can use stateful widgets.

#3. Responsive Interface Design

This is the third key component of the Flutter app design. You will get an extensive range of widgets and tools in the Flutter framework that can help build a responsive mobile application. The user interfaces can easily adapt to the different screen sizes and resolutions.

You can create adaptive layouts with the defined functionality. Moreover, you can also create a constraint-based system to define a more restricted layout.

#4. Material Design

Material design is the language that was created by Google to build stable and reliable interface designs. Flutter follows the guidelines defined by Material Design to create versatile and interactive app solutions. Most of the functionality determined by the Material design is used to create visually stunning app designs.

You can use AppBar, FloatingActionButton and BottomNavigationBar to create a defined interface.

#5. Customizations

The fifth aspect of the Flutter component system is customization. You get excellent opportunities to customize your interface elements with Flutter components. You can even create customized widgets to plan the layout and define the design.

Flutter components will allow you to customize the theme, style and even animations. The component-based architecture induces greater flexibility in terms of design and layout.

  2. As Flutter is a Dart-based framework, you might experience a slight learning curve.
  3. While customized components can help you achieve consistency, you might notice slight pixel-level differences for iOS and Android. They cannot be translated into a native-like application.

Overview of React Native Components

The components or building blocks of the React Native framework are important when planning your upcoming project. They help you create an exclusive structure and explicit app design to attract users. We will discuss the components of the React Native framework that helps design applications.

#1. Component-based Architecture

In React Native, you will use the component-based architecture to create the interface design. The components are the foundational blocks that help derive the ultimate structure. Each component can be reused within the application as needed.

As a result, you can enjoy a modular codebase that is easy to maintain. You can also enhance the capabilities of the React Native application.

#2. JS Components

You generally use JavaScript to create and manipulate components in React Native. A lot of developers also use JSX (JavaScript XML) to create the codebase for the application.

Using JSX, you can define the structure and the appearance of the interface elements. This can occur in a component-defined way. Moreover, you get to use the core components and also build custom components with this approach.

#3. Native-like Aesthetics

React Native is known for rendering UI elements with native-like aesthetics. You will get a native feel and look when you work with the React Native UI components.

They use UIView to render the View in iOS and a native View for Android. Using this method, the framework ensures high-performing and quality app solutions for the users.

#4. Third-party Libraries

The rich and extensive ecosystem supports your goal as a developer in creating unique and highly styled component-based architecture. You can easily extend the functions, create more customized components and build a unique system. All this is possible with the third-party plugins and packages.

Pros and Cons of React Native Components

The React Native components are the foundation of any mobile or web application created with this framework. However, you must know the pros and flip side associated with using the component-based architecture.

Pros of React Native Components

  1. With the React Native reusable components, you can speed up UI development. Moreover, you can create consistency across the application by using the same component design.
  2. As the components are rendered using native UI view approaches, you get a native-like look and performance. This can enhance the user’s experience for mobile and web development.
  3. When you use the accompanying hot reload feature, you can easily upgrade the application with minimal effort. Moreover, you can make changes to the live application without impacting the app’s movement
  4. As it enjoys a large ecosystem combined with an extensive community, you can easily access native-like plugins. You can even use the libraries to build the components. Moreover, you can enjoy the support from developers to solve issues related to plugins or components
  5. Learning React Native and building components is easy if you have a detailed understanding of JavaScript language.

The Cons of React Native Components

  1. If you want to build components that utilize the features or functionality of the device, you must write platform-specific code. This can make the development process slightly complex
  2. You may not be able to access all the aspects of native features or APIs. React Native might not enjoy immediate support for new features or functionality added to the framework
  3. Your app size may be larger than the native apps, which might cause concerns when downloading
  4. Despite being native-like, the performance may not be completely in tune with the native applications. Some of the intensive tasks may take a longer while to finish.
  5. When it comes to learning the native modules, you might experience a slight learning curve.

A Detailed Comparison Between Flutter and React Native Components

It is very crucial to compare Flutter and React Native components to get a real-world view of both frameworks. We have identified a few parameters to compare the two. These parameters will give the exact measure of their ability.

#1 Performance

Both frameworks use different rendering methods and compilation approaches. As a result, it can impact their performance abilities in the long run. Overall, the approach can impact the speed of the application, the development timeline and the overall application performance


Flutter uses a direct compilation approach, wherein the components are directly translated into native code via the built-in engine. This method increases the overall performance of the Flutter application.

Moreover, these compiled components progress at a speed equivalent to the native components. So, you don’t need to go through runtime interpretation which can take time. Lastly, the architecture (widget-based) ensures better response time via smooth and flexible animations.

React Native

In contrast to Flutter’s in-built compilation method, React Native uses the JavaScript bridge to communicate with the native modules. As there is a layer attached to the communication, it can add an overhead to the overall performance.

Owing to this overhead, you might experience lags and performance delays in the long run. This can heavily impact powerful devices. You may need to optimize the code for smooth communication between JavaScript and native code.

The Better One

Flutter has a commendable advantage over React Native in terms of speed and performance. You will notice that this speed advantage can be easily leveraged when you are building applications that are graphic intensive. Moreover, you can also boost real-time interactions with the Flutter applications.

You can also use Flutter components to build custom components for complex logic. React Native, on the other hand, can be a great asset for prototyping and MVP development. You can also use it to build progressive web apps.

On optimizing the React components, you can also enjoy Flutter-like performance.

#2. UI Design and Customization

It is important to look at the Material Design abilities of Flutter and compare it with the native rendering approach. Moreover, we should also look at the styling system adopted by React Native. It is equally important to compare it with the widget library approach.


Flutter has an expansive widget library that offers Material Design widgets to boost interface interactions. The high-end UI can enable better experiences in the long run. These widgets are designed keeping in mind the Material Design guidelines specified by Google.

Flutter can easily achieve consistency in look and feel with these widgets. Moreover, they can offer better customizations that can enhance the look and feel of the Flutter interface. You can even create custom components from Flutter’s widget library to define unique aesthetics.

Lastly, you can reuse the widgets or build on the existing architecture to deliver consistency.

React Native

React Native extends a more platform-specific appearance through native rendering components. The design approach ensures a more native-like appearance and appeal. Moreover, it ensures a better and more consistent appearance throughout the application.

The customizations also consider platform-based components or styling elements. They tend to merge with the device components or features, which is why this style is important. The ecosystem is full of third-party libraries and plugins that support this approach.

The Better One

React Native and Flutter both face issues when trying to keep up with consistency. They are unable to exact the platform-specific aesthetics as there are some elements that differ between iOS and Android.

React Native may need to use more resources as compared to Flutter to achieve consistency and a native-like feel. However, if carefully defined, React Native offers more native-like experiences to the users.

Flutter has a straightforward design approach. However, you may not enjoy the native feel or experience with this approach.

#3. Development Speed

The third and most important parameter that you must consider when choosing between React Native and Flutter components is speed. This would include the speed of development and the overall impact on the timelines for the project.


Using Flutter’s hot reload feature, you can notice the code changes while your application is live. These changes are instantly implemented in the application. As soon as you are satisfied with the changes, you can press hot reload, and the changes will be updated.

As a result of the hot reload, you won’t face any issues in the current application state. This is a great quick-fix method that can improve iteration development and app debugging. Overall, it can enhance the developer’s productivity and help you attain milestones faster.

React Native

Akin to hot reload, React Native offers fast refresh. This is a similar method. However, in this case, the developers will notice the changes made inside the JavaScript code during runtime.

It can help developers check the impact of code changes in a live environment immediately. However, the code changes are restricted to JavaScript code only. You won’t be able to complete fast refresh on the native modules. In this case, you will take the traditional route that can impact the speed of development.

The Better One

The Fast Refresh (React Native) and Hot Reload (Flutter) features can help in iterative development. It can help the developers notice the bugs faster and debug them with greater speed. Moreover, it can impact the speed of project completion.

As a result of these features, you will observe a quick development cycle. This can help you achieve better and with greater speed. Flutter focuses on resource efficiency while React Native can consume more resources if the corrections are within the native modules.

Overall both frameworks offer excellent ways to improve the project timelines and ensure speed of development. They can impact your developer’s efficiency and help you gain a competitive edge.

#4. Community and Ecosystem

The community or ecosystem is a great comparison factor as it showcases the developer’s interest in the framework.


There are about 161K followers on Twitter for Flutter and 188k on Facebook. Flutter has earned 134K stars on GitHub and has over 957 contributors.

React Native

React Native has 159k people on Facebook and over 130k followers on Twitter. On GitHub, they have earned 100k stars and have over 2270 contributors.

The Better One

The size of the React Native community is definitely bigger and better compared to Flutter. There are more contributors to this framework when compared to Flutter. You can hire React Native developers India for better outcomes.

As it is promoted by Facebook, there are more contributors and a larger ecosystem that offers better tools.


Flutter and React Native offer a unique and defined approach to component development and UI design. While Flutter takes the component (widget-based) architecture, React Native supports a more native-like rendering method.

React Native utilizes JavaScript to build the code, which also requires a separate bridge to complete rendering. It impacts the performance of the application. While Flutter uses a Material Design approach for guided interface design, React Native depends on a native-like styling approach.

While they may have different approaches toward development, the common factors include- allowing component reusability and providing customizations.

Making the right component choice is equally important. You can choose between React Native and Flutter component design approaches based on:

  • Your project requirements
  • Timelines of the project
  • Developer’s experience
  • Community support needs
