Use case

This function is used to tell wm to raise the window.

For example, on wayland, the protocal is https://wayland.app/protocols/xdg-activation-v1

In qt, for example https://github.com/Nheko-Reborn/nheko/blob/master/src/ChatPage.cpp#L150.

And I think there is similar function in gtk.

By the way, I also think this feature is very important on windows and macos

Proposal

add a similar function to flutter, to request the window to the top
