*What’s so Special about Flutter?* First, its ability to develop cross-platform apps from a single codebase makes it stand out from the other frameworks. Flutter allows developers to design attractive apps without sacrificing speed, quality, or performance. The rendering engine of Flutter is primarily written in C++. Another notable feature of Flutter is its wide range of customizable widgets and components.

## Features Of Flutter

Flutter has various features, making it a popular choice among developers. Here are some key features of Flutter:

* **Widget-Based Architecture: **In Flutter, everything is a widget, including the UI elements, layout components, and even the whole code app. This widget-based layout makes development easier and allows for the building of rich and interactive user interfaces.

* **Expressive UI:** Flutter’s widgets allow developers to create expressive and visually appealing interfaces. The framework supports intricate animations, transitions, and effects, providing a polished and engaging user experience.

* **Hot Reload:** Flutter’s Hot Reload feature is like a live preview of your code. You can change your code and see the results immediately in the app’s UI. This makes it easy to experiment with different ideas and quickly fix bugs.

* **Native performance:** Flutter offers native performance by compiling its code to native ARM code, ensuring smooth and responsive apps. This reduces the performance disparity that is sometimes encountered with cross-platform frameworks.

* **Platform APIs Integration:** Flutter Platform APIs Integration allows developers to access the native platform APIs of the underlying operating system from the Flutter app. This can be used to access the device’s camera, contacts, or location or to play audio or video.

## In Flutter, everything is a Widget!

Flutter employs a Widget-based UI approach, where widgets are the fundamental elements of the app’s user interface, ranging from buttons to entire app structures. These widgets are organized into a hierarchy known as the “widget tree,” where each widget nests within its parent and inherits context. This hierarchical structure extends to the root widget, either MaterialApp or CupertinoApp, simplifying UI development and enabling the creation of complex interfaces through widget layering and nesting.

## Limitations Of Flutter

Flutter, while robust and versatile, also has limitations. Here are some key constraints developers should know when working with Flutter:

* **Large App Size:** Flutter applications could exhibit a greater file size than native apps. This is mainly attributed to including the Flutter engine and framework, leading to an augmented initial download size for the app.

* **Learning Curve for Dart:** For developers accustomed to more commonly used languages such as JavaScript, Flutter’s use of the Dart programming language may be a learning curve. While Dart offers many advantages, developers may need time to master it.

* **Limited 3D Graphics Capabilities:** Flutter’s support for 3D graphics and AR/VR applications is limited compared to other frameworks, making it less suitable for applications heavily reliant on these technologies.

## What is React Native?

React Native is a JavaScript framework created and managed by Meta Platforms to create natively rendered iOS and Android mobile apps. It’s developed using React, Facebook’s JavaScript toolkit for building user interfaces, but instead of being aimed at the web, it’s aimed at mobile applications.

![](https://cdn-images-1.medium.com/max/2000/0*N9VwpnjEtlkIgk69.png)

“*Many platforms, one React*” — Through React Native, we can create platform-specific versions of components so a single codebase can be shared across different platforms. This is how React Native makes it simple to build for both Android and iOS simultaneously.

## Features Of React Native

React Native has various features. Listed are some of the key features of React Native:

* **Unified Multi-Platform Development:** The core principle of React Native is that the code you write should run on almost all popular mobile devices. Among them are Windows, Android, and iOS. Writing code in Swift for iOS, Java for Android, or C# for Windows is unnecessary.

* **Reusable Components:** React Native is a component-based architecture that allows developers to build modular user interface functions known as components. It allows developers to create reusable UI components that can be shared across different parts of the app or even between other apps.

* **Live Reloading:** Similar to Flutter’s Hot Reload feature, the “live reloading” feature of React Native enables developers to see the effects of code changes in real-time without rebuilding the entire app. This speeds up the development and testing process.

* **Rapid Development:** React Native advocates a structured and systematic approach to development, making it easier to maintain and scale up projects as they get large. For Facebook, accelerated development is crucial because React pages load noticeably quicker than conventional JavaScript pages.

* **Open Source Contribution:** React Native has a rich ecosystem of third-party libraries and open-source contributions. These libraries provide ready-made solutions for a variety of capabilities, hence increasing development efficiency. The collaborative nature of open-source contributions guarantees that React Native developers have access to a wide range of tools.

## React Native’s Component Magic!

React Native employs JavaScript to access platform APIs and define UI using React Components. Components are reusable and testable code units, much like Flutter’s Widgets. React Native offers essential Native Components, ready to use, for building apps called **Core Components**.

Core Components are cross-platform, acting as a bridge between the app’s JavaScript code and the native components on each platform. Core Components provide an additional level of abstraction, simplifying development and allowing developers to create uniform user interfaces across platforms.

## Limitations of React Native

Here are some constraints to consider when working with React Native:

* **Platform Dependencies:** While React Native enables cross-platform development easier, remember that certain features and components may be platform-specific. This could present challenges when aiming to provide a consistent user experience across several platforms.

* **Third-Party Dependencies:** In React Native development, it’s commonplace to depend on external packages and libraries. However, the quality and maintenance of these packages can vary, potentially leading to compatibility issues and requiring additional attention during app updates.

* **Memory Fragmentation:** React Native relies on JavaScript, which has its own garbage collection mechanism. The JavaScript runtime and the bridging mechanism can cause memory fragmentation, making it challenging to allocate large contiguous blocks of memory efficiently.
