How to Run Your Flutter Linux Desktop Application in Full Screen

As the popularity of Flutter continues to grow, many developers are eager to create engaging applications that deliver optimal user experiences. One common requirement for desktop applications is the ability to run in full screen mode. This not only enhances usability but also immerses users in the content of the application. In this guide, we will explore how to enable full screen mode for your Flutter application on Linux, addressing a common challenge faced by developers.

The Problem: Running Flutter Apps in Full Screen on Linux

If you're developing a Flutter application for Linux, you may have found that setting it to run in full screen isn't straightforward. Some developers have turned to the WindowUtils plugin, only to discover that it primarily supports desktop embedding. This leaves many in search of a simple yet effective solution to implement full screen functionality in their applications.

The Solution: Modifying Your Application Code

Good news! You can enable full screen mode for your Flutter Linux application by making a small adjustment in your application code. Follow these steps carefully:

Step-by-Step Guide

Locate Your Application Files

Open your Flutter project directory.

Navigate to the linux folder within your project.

Open the Main Application File

Find the file named my_application.cc. This file contains the native code required to run your application on Linux.

Edit the File

Open my_application.cc with your preferred code editor.

Search for the line that sets the default window size. It should look something like this:

Add the Full Screen Code

Immediately after the line that sets the window size, insert the following line of code:

Save Your Changes

Once you have added the line of code, save the my_application.cc file.

Run Your Application

Build and run your Flutter Linux application. It should now launch directly in full screen mode!

Why This Works

Flutter runs on top of GTK, the GIMP Toolkit, for Linux desktop applications. By utilizing the gtk_window_fullscreen() function, we leverage GTK's built-in capability to display applications in full screen. This method is straightforward and does not require additional dependencies, making it an efficient solution for your Flutter applications.

Conclusion

Enabling full screen mode in your Flutter Linux desktop application is a simple but impactful enhancement that can improve the overall user experience. By following the steps outlined above, you can quickly implement this feature and immerse your users in your application content.

Now you have the tools you need to transform your Flutter applications into engaging desktop experiences. Happy coding!
