Is somone working on this? If not, I would like to work on this feature.

Hi @Spyy004, I don't believe anyone is working on this specifically, although it may conflict with @josxha's work on gestures, so I'll let him confirm.

Spyy004 commented 1 year ago

Okay!

josxha commented 1 year ago

Hi @Spyy004, I'm the person who is working on the gesture system rewrite over in https://github.com/fleaflet/flutter_map/issues/1715. You can start working on the feature right now if you like. I'm going to merge your changes afterwards into the rewrite.

Cool thanks!

So I am a bit confused on how to move ahead. I know what I have to do but I want to know the right way to do it. If I want to detect two finger taps, I would need to know the pointerCount details which is provided by ScaleStartDetails. Currently when I tap with two fingers, the onTap triggers but there is no way to figure out number of pointers touching the screen because TapPosition class doesn't give me that detail. So should I modify the Tap position class and handle the two finger tap in the ontap method itself or should I create new methods in position_tap_detector_2 and handle the two finger tap. A little guidance would be helpful!

In that case it's probably better for you to wait until the rewrite is finished. It's probably more straight forward to implement it afterwards.
