2 months ago Hey, thanks for this amazing library! I've used a while ago for this FPS-style camera implementation.
However, upon testing it more recently, it appears that with new Flutter versions it now only works while the mouse button is down, i.e., while dragging. While not dragging, the mouse pointer does "disappear", but I don't get mouse events via
onPointerDataPacket. It seems by the readme that this is an "expected" issue, and that this packet is not really meant for what I thought it was (first person camera). And the events are intentionally only sent when the mouse button is down. Is that correct?
With the streaming mode, that's correct. It only works with button being down. With that other mode, it should also work with other "triggers". Are you on Windows?
And, more broadly, is FPS-camera a use case that you wish to support with this library? Or is this out-of-scope?
I think it would be a nice addition to this library and it somehow fits in, but I currently don't have the time to add it. But if someone else wants to give it a go, sure!
I also have tried this simplified version based on the example on the repo, which also does not work:
Does it work when you download this repo and start the example app as is?
