mouse cursor support

[ardera]

• wait for Raspberry Pi foundation to add hw cursor support to DRM, or
• use the embedder API to add a new layer on top of flutter (also a composer), or
• maybe there's some other way to get DRM to draw a cursor on top of the other planes, or
• build a package for flutter that provides software cursor support

I thought about this for a while, but I'm not sure it's a wise choice to implement it.

The thing is, if I add mouse support, it will be without mouse acceleration and without any configuration options. So the mouse will feel kinda raw, and not at all like what you're used to on a normal Desktop.

That means mouse support would only be useful for debugging purposes. But since touchscreen input seems to work quite well right now, I doubt anyone needs mouse input for debugging purposes.

That's why I think it's not that useful right now.

But of course, I'm open to discussion about that.

Hi, in my opinion the mouse support is needed. How you said only for debugging purposes. For example, I don't have a touch screen display yet, and at the moment I'm stuck at the first screen because I can't interact with the app.

TL;DR
We need the mouse support

Agree. I'm currently investigating a borrowed RPI as a possible path forward on a project, but I'm not quite ready to make the investment on a touchscreen yet. Even if it's kind of nasty, basic mouse support would be nice to see how smooth/interactive flutter apps can be for those without touchscreens. Please consider it?

Okay, that seems reasonable, I'll implement it when I have time

That would be really nice, Thanks!

So just to make sure: is mouse control supported with the latest flutter_pi release? Anything that needs to be configured to enable it ?
It doesn't seem to work here.

@ondrej1024 It only works when the GPU supports hardware mouse cursors. If they're not supported you should see some error messages in the flutter-pi output.

You can use a software mouse cursor though when hw is not supported: https://gist.github.com/ardera/e7ddf7c8e477d258a26dfa9c40002626
