So, let’s get started!

What is Flutter?

Flutter app development

Flutter is a free, open-source technology developed by Google and officially launched in December 2018. It’s designed for coding and building native apps for both Android and iOS. 

Flutter combines ease of development with performance and visual consistency. Its programming language, Dart, was initially designed to replace Javascript. Flutter’s ability to create cross-platform applications using a single codebase allows organizations to develop an app that’s accessible on the web, mobile, and desktop. The intuitive and easy-to-navigate apps created with Flutter make it a preferred choice for companies with extensive framework needs, such as Alibaba, eBay, and Google Assistant. 

Let’s find the top  flutter development companies in 2024 here.

How does Flutter operate?

Flutter’s framework consists of a flutter engine, a foundation library, and widgets. Its unique approach to app development involves declarative UI writing, where development starts from the result. This means developers need a clear vision of the UI before starting the development of any element. 

They can create the entire user interface by combining different widgets, and Flutter also allows developers to create custom widgets integrated with existing ones. To improve the user experience and application capabilities, Flutter offers several software packages for access to Firebase and Redux data warehouses.

What is React Native?

React Native app development

React Native is a widely used mobile framework based on Javascript that allows the development of natively rendered mobile applications for Android and iOS using the same codebase. 

It was developed as an open-source project by Facebook in 2015. In just a few years, React Native has become a leading solution for mobile app development, with notable examples including Instagram, Facebook, and Skype. The ability to write code just once results in significant time and resource savings.

How does React Native operate?

React Native merges Javascript and JXL (a unique code resembling XML). This framework can communicate with both Javascript-based and native app threads. Unlike other cross-platform development solutions, React Native doesn’t render web views in its code and operates on existing native concepts and components. By bridging Javascript and native code, React Native enables bidirectional communication.

For Example: Imagine you’re making a simple to-do list app. Here’s how React Native might work behind the scenes:

  1. Building Blocks:
    • Instructions (JavaScript): You write code (like giving instructions) that tells the app what to show (the to-do list) and what to do when you tap something (like adding a new task).
    • Pre-made Items (Native Components): Instead of drawing everything yourself, you use pre-built things like boxes (to hold tasks) and buttons (to add new tasks). These are like pre-made Lego bricks for your app.
  1. Putting it Together (Rendering):
    • Plan (Virtual DOM): The code creates a plan (like a blueprint) of how the app should look, including where the boxes and buttons go. This plan is invisible to you, but it helps React Native figure out what to change.
    • Spotting Changes: Imagine you add a new task. React Native compares the new plan to the old one and sees what’s different (the new task).
    • Updating the App: React Native only updates the parts that changed (the new task box) instead of rebuilding the entire app. It tells the pre-made items (boxes and buttons) how to arrange themselves based on the changes.

So, you write code (instructions) using pre-built components (boxes and buttons), and React Native takes care of the behind-the-scenes work (making the plan, spotting changes, and updating the app) to show you a smooth and functional to-do list app.

What Makes Flutter Stand Out?

1. Efficient Coding

As a recent addition to the app development platforms, Flutter offers a fast way to build high-performance applications.

2. Hot Reload

This feature allows developers to see changes in real time, enhancing efficiency and productivity. Flutter’s hot reload stands out among similar features from competitors by letting developers pause code execution, modify code, and resume from where they left off, leading to impressive speed.

3. Widgets

Flutter’s use of ready-made apps ensures a uniform development and design model. These Google-based widgets offer superior code quality and outperform other open-source frameworks. Many are customizable, adhering to both Material and Cupertino styles, which is a significant advantage.

4. Less Coding

 Flutter’s coding language, Dart, compiles directly into the ARM code of mobile devices, accelerating applications and enabling faster launches. Flutter simplifies developers’ work through its native codebase and third-party integration.

5. Custom Design

Flutter includes an open-source, high-performance graphics engine called Skia, also used by Adobe, Chrome, and Amazon Kindle. This powerful tool lets users create custom-designed applications that deliver equally good experiences on iOS and Android devices. Plus, it eliminates the risk of UI failures during software updates.

6. Consistent UI Across Platforms

Flutter provides the same user interface and business logic on Android and Apple devices, ensuring a smooth experience. This is particularly important for brands with distinctive and superior corporate styles.

What are the Drawbacks of Flutter?

Despite Flutter’s numerous advantages, it has its downsides.

1. Lack of Third-Party Libraries

Third-party libraries significantly influence software development by providing developers with additional, often free, open-source, and pre-tested features. As Flutter is a relatively new platform in the mobile app development market, it’s still evolving and thus offers limited options for third-party libraries and packages.

2. Large File Size

One notable disadvantage of Flutter is the large file size of its apps. With mobile users worldwide needing more memory space and many older devices unable to store extra apps, users might have to choose between an app, photos, or other files. A smaller file size would improve runtime and performance, which is a drawback for Flutter.

3. Learning Curve

Although Flutter is a straightforward language, it requires programmers to learn Dart first. This additional learning phase can increase the time and cost of a project.

What Makes React Native Stand Out?

1. Superior Performance

The effectiveness of a platform is gauged by its ability to enhance performance using native modules and controls. React Native interfaces with native iOS and Android components, generating native API codes without interference. The use of separate threads for native APIs and UIs in React Native leads to performance improvements.

2. Live and Hot Reloading

The live reloading feature compiles and reads programmers’ changes, providing a new file to the simulator that automatically restarts the application. Hot reloading allows code changes to be viewed without recompiling the app. This feature of React Native enables developers to see results immediately after making code changes, reducing wait times.

3. Streamlined UI

React Native offers a straightforward and uncomplicated user interface. Its architecture is more akin to an open-source network than a traditional one. This platform uses a software interface to eliminate unnecessary elements, facilitating appropriate sequencing for app creation. With user experience as the primary focus, apps developed with React Native offer a more seamless UX, responsive UI, and quicker load times.

4. Modular Design

A modular design and architecture allow for instant app upgrades or updates. Thanks to its intuitive interface, React Native enables other developers to move into someone else’s project to build upon or modify it. Additionally, testers need less time to understand the program logic and create suitable test scenarios.

What are the Drawbacks of React Native?

1. Compatibility and Debugging Issues

Surprisingly, six years after its launch, React Native is still in beta. Furthermore, because React Native is built using Javascript, C/C++, and Java, the debugging process is complex and tedious. To mitigate this issue, integration with Flipper is necessary, providing a suite of tools for the debugging process.

2. Complex User Interface

If your goal is to develop a mobile application with numerous transitions, animations, and interactions, React Native may not be the best choice. Even having a gesture responder won’t solve the problem, as Android and iOS touch subsystems have unified APIs and are quite different.

3. Immature Framework

With ongoing advancements in React Native app development, developers often struggle to adjust and adapt to the changes. In its pursuit of speed, React Native has lost its credibility, becoming overly mature for Android and iOS. The flexibility of React Native apps is also subpar compared to native applications.

4. Difficulty Building a Cross-Platform Team

As a cross-platform technology, a React Native team should be well-versed in web technologies (Java, React) and native technologies (CI, UX technologies). Building a team to address all the challenges that arise in developing cross-platform applications can be challenging.

When to choose Flutter?

  • Performance and Customization are Paramount: You prioritize high-fidelity graphics, complex animations, and a truly unique user interface (think gaming apps, social media with custom layouts, or visually-driven e-commerce).
  • Rapid Development is Crucial: You need to build an MVP or prototype quickly to test core functionalities and gather user feedback (ideal for proofs-of-concept or rapid iterations).
  • Offline Functionality Matters: Your app needs to function without an internet connection (travel guides, educational apps, or situations with unreliable connectivity).

When to choose React Native?

  • Fast Prototyping is a Priority: You need to create a basic concept app quickly to showcase functionality or gather early investor feedback (proofs-of-concept or simple business apps).
  • You Have a JavaScript Team: Your developers already have strong JavaScript skills and can leverage their existing knowledge for mobile app development (especially beneficial for companies with established web development teams).
  • Third-Party Libraries Simplify Development: Your project can benefit from pre-built functionalities offered by React Native’s extensive library ecosystem (e-commerce apps integrating payment gateways or social media apps utilizing user authentication features).
  • Frequent Updates are Needed: Your app requires regular updates for security patches, new features, or A/B testing of UI elements (common in news or finance apps).
