Markers moving around map (when pinching/rotating) since updating to 1.3.0

Since updating to the new version, both here and in flutter_map I get the behavior as represented in the recording.
Has anyone faced this issue so far? I might have missed some new configuration though...

Hey, I am facing the same issue and I almost exactly copy pasted my configuration from 0.4.3 to 1.3.0. I was about to go swooping through the migration for FM V6 to see how much has changed but haven't got the chance yet.

I think it comes from flutter_map replacing anchor with alignment.
I'm not so sure, the alignment is needed to reverse in order to use in the marker cluster code.

Confirmed that this affects the example as well.
@lpongetti can we have your insights here, please? 🙏
I can try and dig into the codebase, but I have zero context on both packages 😕

It was working fine in flutter_map: ^6.0.0-dev.3. I think this issue started occurring after flutter_map removed anchorPos in flutter_map: ^6.0.0.

Thanks @shrijanRegmi! How did you figure out that was the issue?

@jfmlima I spent lots of hours debugging the issue but nothing helped until I looked into the flutter_map commits and found out about MobileLayerTransformer which was missing in our case.
