Cross-platform overview

Cross-platform development is the process of building an app or software solution that can run seamlessly on different operating systems. Users with different devices can access and enjoy the features and functionalities of solutions built through cross-platform development.

Flutter as a cross-platform development framework

Created by Google, Flutter is an open-source framework used by developers to create software solutions for applications that can run on different platforms using a single codebase.

Why use Flutter for cross-platform development? Top benefits of Flutter

When compared to other cross-platform frameworks, Flutter has unique features that make it stand out. Some of the top reasons why Flutter is the best framework for cross-platform development, benefiting both businesses and development teams, include:

• Seamless development process

Flutter gives developers an easy time throughout the development process. Developers use the same codebase when creating an app for different operating systems, thus simplifying the process and creating a smooth working environment. What’s more, Flutter has hot restart and hot reload functionalities, which allow developers to implement real-time updates without restarting the app. As a result, it accelerates the development process while simplifying most of the complex tasks for developers.

• Better performance

Performance is a key aspect of app development. While users keep on searching for speedy-performing apps, developers are searching for tech solutions that enhance the development of high-performing applications, and Flutter is one framework that enhances the development of high-performing apps.

This is because Flutter is a mobile SDK without a webview or JavaScript bridge required for connecting apps and platforms. That is why developers using Flutter can produce apps that perform better with intuitive features.

• Widgets & compatibility

Widgets are the building blocks that make up the entire app. We have widgets that can be customized and the ones that are ready made. In Flutter development, developers can customize different functionalities from widgets. Widgets, being part of the entire app and not platform-specific, make the end product to be compatible with different operating systems and platforms.

• Open source with a supportive community

Flutter, being an open-source framework makes it free to use. Although it is still a growing framework, it has a supportive community that is growing day by day. Its remarkable documentation makes it easy for developers to troubleshoot issues during the development process.

Above all, there are Flutter learning resources including YouTube videos and extensive blogs for Flutter beginners and for developers who want to polish their Flutter development skills.

Another reason making Flutter stands out as the best cross-platform framework is the faster time-to-market process.

Flutter boasts a wide range of features that accelerate the development process, making it easy to release the product to the market faster in a timely manner.

Again, since Flutter uses a single codebase for different platforms, it reduces the overall development period. By using the same code base for different platforms, Flutter enables developers to focus on finalizing the development process instead of writing different codes for different platforms, which can be a technical process that takes more time.

• Reduced Testing Process

As a leading cross-platform framework, Flutter has a streamlined testing process. With a single codebase for iOS and Android platforms, Flutter eliminates the need to test different platforms separately, thus speeding up the testing process.

This is contrary to the traditional development strategies where testing is performed for each platform. While Flutter reduces the testing time significantly, it also reduces the chances of platform-specific issues arising once the product is released.

By embracing Flutter testing approaches, developers can release features and functionalities faster at reduced costs while ensuring better user experience across different platforms.

• Brand consistency

For developers or business owners who want to maintain app consistency across different devices, Flutter is the ideal framework here. Flutter has a consistent UI and the same business logic for all platforms. This is because Flutter uses a single codebase to leverage all the functionalities of different operating systems.

This makes the whole development process smooth while ensuring the user experience is the same across different platforms.

• Hot Reload Feature

The hot reload feature is one notable benefit of Flutter in the development process. The feature allows developers to review and update changes in real time without having to start the whole process again.

As a result, hot reload speeds up the development process by enabling developers to iterate, perform testing, and tailor the code to align with business goals and user needs.

This, in turn, enhances productivity by allowing developers to identify & address issues in a timely manner.

Why use another cross-platform framework and not Flutter? Top challenges of using Flutter
