ElevationPoint class and LatLng

Hi there,
I'm trying to use this absolutely awesome plugin to show a terrain profile. That part works beautifully, but I'm trying to implement the hoverPoint feature over a line to show where the user is on the terrain profile. When trying to construct the MarkerLayerOptions...
MarkerLayerOptions(markers: [if (hoverPoint is LatLng)Marker(
point: hoverPoint,
width: 8,
height: 8,
builder: (BuildContext context) => Container(
decoration: BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.circular(8)),
))]),
I get an error about the point argument of HoverPoint (type ElevationPoint) not being assignable to the class LatLng*.
I understand how to construct a LatLng pair in lieu of an ElevationPoint, the problem is that the ElevationHoverNotification notification requires an ElevationPoint.
I fear something with null safety may have affected this? But I just ask if anyone might know of a workaround, as I would love to have this feature.
Anyway, thank you for this wonderful plugin regardless that I will be using in my current app project.

Hi there,
Seems like a bug on the example project. What's weird is that it works on my own.
I'm working on it, will release soon.
Thanks for your kind words! :-)

@W2NJL can you check #8 and tell me if that fixes your case?
If it doesn't, could you
flutter doctor -vso I can reproduce your issue? On my side it is working fine :-)
Hello @HugoHeneault ,
Thanks so much for the reply and checking this! So, after making the change you suggested I still am seeing an error. First, here is my flutter doctor -v results:

Please let me know if you need anything else from me - I would be happy to provide!!

Update - I got it to work! This was 100% my fault for messing around with the Flutter Maps package and changing its dependency from LatLng2 to just LatLng. I updated Flutter Maps to the newest version and everything is working great. I am so happy I even have a screen capture of what I put together in action haha:

Thank you for your time looking into this and keep up the awesome work. This plugin is amazing.

Cool that you got it working :-)
I'll submit the PR anyway as it's cleaner than before.
Have a nice day coding!
