Gesture detect Middle Mouse Button #62488
Description
Use case
There seems to be a PointerEvent for the middle mouse button, however, I see no way to access it from widgets.
Proposal
It would be very useful if you could have an onMiddleMouseButtonPressed callback on the widget level.

It's possible to do this by looking at
TapGestureRecognizer, you can see how it's implemented, and that recognizer can participate in the gesture arena. Basically you have to use a lower level interface thanGestureDetector.It would be good, however, to support
onTertiaryTap*for the gesture detector.creativecreatorormaybenot commentedon Jul 30, 2020
@gspencergoog Yes, thank you. I was aware of that, however, it would be useful to have this option on the widget level. Do you think making a PR would be benificial?

I mean that it would be nice to not have to use
RawGestureDetectoror a customRenderObject.gspencergoog commentedon Jul 30, 2020
Yes, I agree. If you'd like to make a PR, that would be great, and otherwise we will get to it eventually. You'll want to look at
onSecondaryTap{Up,Down,Cancel}on theGestureDetector, and call itonTertiaryTap{Up,Down,Cancel}. There shouldn't be a plainonTertiaryTapbecause we don't support double-tap on the secondary button, much less the middle button, andonTapis there mainly to be able to determine the difference between double and single tap.creativecreatorormaybenot commentedon Jul 31, 2020
@gspencergoog That sounds good. I think that I will open a PR for it 👍🏼

@gspencergoog I openend a PR, according to how I understood your guidance.
I really hope that I got it right 😂 Performing changes for that is a mess 😅

Thanks! I'm actually out on vacation this week, so it'll be a bit until I get to it, but maybe someone else will take a look before then.
