Focus Issue While Using Virtual Keyboard

[Zhairgling]

Description:
Hello,

I am currently working on a Flutter application for Windows that acts as a virtual keyboard. I am using the window_manager plugin to manage the application window.

The issue I am facing is as follows: when a user clicks on a key of the virtual keyboard, my application window gains focus, preventing text input in the currently focused application (e.g., a text editor or web browser).

Questions:
Is there a method to prevent the application window from gaining focus when a user interacts with it?
Is it possible to use window_manager in combination with Windows API calls (using the win32 package, for example) to manipulate application focus in a more granular manner?
Thank you in advance for your assistance.

Best regards,
