current heading

[akifbora]

Is there any method that I can get the current heading (bearing) value?

It is not documented but it is possible to subscribe to the locationManager which returns an event with a heading. It is used in the UserLocation component

import { locationManager } from '@rnmapbox/maps'

const onLocationHandler = (event) => {
    if(event?.coords?.heading){
        //
    }
}

locationManager.addListener(onLocationHandler)
locationManager.start()

locationManager.removeListener(onLocationHandler)
// careful when stopping the location manager as this can stop
// the user location update in a map view if it is being used
locationManager.stop()

thanks for the reply. but is it possible without location manager? something like map.getBearing() in mapbox-gl-js?

I'm not sure. You'll have to dig through the code to see, else there are some other location packages you could use.

• @react-native-community/geolocation
• expo-location

I think I was misunderstood. We can set heading like cameraRef.setCamera({ heading: 30 }), but I don't see any method to get the current heading/bearing value. Has the camera class any method to get map's current bearing value without location data?
Please refer:

Sorry for taking your time.

I got it. there is no method to get current bearing and pitch on mapRef. I implemented and I will send a pull request if needed.
