This is quite a bit problematic. On MacOS, you can get transparent windows already using window.setStyle(frame:windowFrame.noFrame)
. But generally there is no click through on Mac. I think it could be done by disabling mouse events on window completely and then registering to handle global events, but that seems very messy.
Click through on WS_EX_LAYERED
only works for GDI, where the window transparency is used for determining click through region but the buffer is entirely in RAM. This is not compatible with accelerated applications such as Flutter. Much more performant way would be to simply use DirectComposition and removing redirection bitmap. I did submit a Flutter PR for this, but it is blocked on missing skia angle functionality. And again, as far as I can tell there's no documented way to get click through for hardware accelerated applications.
IIRC It is also possible to have transparency in windows using DwmExtendFrameIntoClientArea
, but that I think that also works on Windows 10 only.

Is there any updates to this? With plugins like window_manager and flutter_acrylic, we now know for sure that it is possible.
How can we somehow implement this here?

I've also fixed this, sorry about that. Just need to set the background color to transparent
