How to implement a fixed label on yakarts with geolocation?

Question

Yandex maps

Please tell me how to implement this: jsfiddle.net/doktormolle/jcHqt but on yakarts.
Meaning: the mark is fixed in the center, only the map moves, and where the mark turned out to be, the location is determined. By analogy with yataksi.

Answer 1

You can take the marker from the example as it is, and use the getCenter method to determine the position . Somehow so .
