When developing a cross-platform application, we can think of two popular frameworks: Flutter and React Native. Entrepreneurs struggle with this constant debate of Flutter vs. React Native. Which framework is ideal for cross-platform development? 

Let us find out in the blog.

What is Cross-Platform App Development?

Developers can save time, effort, and money when there is no need to build specific applications for each platform. By utilizing cross-platform development frameworks, developers can create code once and distribute it across various platforms, which can help them expand their audience and deliver a consistent user experience.

How Does Cross-Platform App Development Work?

By utilizing frameworks that offer a layer of abstraction, cross-platform app development enables programmers to write code in a single language and compile it into platform-specific binaries. Using these frameworks’ APIs, developers can construct apps with functionality and features similar to native devices.

A brief explanation of cross-platform app development

Choosing a Framework: A cross-platform development framework is determined by developers based on their needs and preferences. The right choice of framework is the key to building a successful application. The popular frameworks include Flutter, React Native, Xamarin, and Ionic. 

Writing Code: Developers can write code in a single programming language, such as JavaScript, Dart, or C#, using the chosen framework. The application’s logic, user interface, and functionality are all built on this code.

Abstraction Layer: Cross-platform framework serves as an abstraction layer by offering APIs that provide developers access to the native features and functionalities of the target platforms. By handling platform-specific tasks, these APIs guarantee a consistent user expert audience across all devices.

Compilation: The framework’s tools and compilers translate the code into platform-specific binaries, such as APK files for Android or IPA files for iOS. The resources and instructions needed for the program to function on the individual platforms are contained in these binaries.

Testing and deployment: To ensure the app’s usability, performance, and cross-platform compatibility, developers can test it on emulators, simulators, or hardware. Once all requirements have been met, the built binaries are released to the relevant app stores or other distribution points for customers to download and install.
