Does it work for Vaadin 21+?
I didn’t test it, but there is nothing in the source that seems incompatible.
So I’m quite confident it will work. If not you can open an issue here: https://github.com/jcgueriaud1/vaadin-geo-location-flow/issues
I downloaded the sources and bumped vaadin to 23.1.6. I just had to refactor one component import that was moved to a new package in Vaadin. It worked fine. Didn't try to get it to work unmodified. (And I learned it needs https for Android browsers :-)
