Hi,

Can you please provide an example on how to use the `Zoom` property of `MapView`?

I have been trying different ways but I cannot make any zoom to the map camera.

Additionally, can you please explain how to use the methods that are exposed as JS API? I mean, how do you get the instance reference of the object to use any of the methods.

Thanks

+1 for the `Zoom`-Property. It doesn’t seem to have any effect on the camera.

Zoom currently behaves differently on iOS and Android. For instance an Android zoom value of 10 is about equal to an iOS zoom value of 3000 or so.

Can you tell me which platform you are testing on? iOS saw a recent fix to setting the initial zoom level on startup…

Hi Andreas,

I’m testing on Android. I’ve tried multiple zoom values from 1 all the way up to 200000 - no changes.
