Please add the documentation too with platform specific 🤗
Can this be extended to iOS too? AppleMap and GoogleMap ?

Thank you

[sytolk]

@rborn I think that Documentation for onUserLocationChange exist:
https://github.com/react-community/react-native-maps/blob/master/docs/mapview.md#events

Callback that is called when the underlying map figures our users current location (coordinate also includes isFromMockProvider value for Android API 18 and above). Make sure showsUserLocation is set to true and that the provider is "google"

this is only minor change that add timestamp parameter to location object received on RN side and I don't think that that there is need documentation changes

@sytolk what about iOS ?

[sytolk]

sorry but I cannot test onUserLocationChange on iOS.
I suppose that this is the line that is need timestamp to be set:
https://github.com/react-community/react-native-maps/blob/master/lib/ios/AirGoogleMaps/AIRGoogleMap.m#L451

https://developer.apple.com/documentation/corelocation/cllocation/1423589-timestamp
and maybe this row is missing for iOS ?
@"timestamp": @(location.timestamp),

but I'm Android developer and cannot testing it on iOS. Can I add this row in PR or you prefer to open new issue for iOS?
