Description of the bug
I'm trying to detect camera movement events (e.g. onCameraIdle, onCameraMove) using the Navigation SDK for React Native, but these listeners don't appear to be exposed in the current version. I’ve checked the documentation and tried using mapViewCallbacks, but no camera-related events are triggered.
Would it be possible to expose these listeners or provide an alternative way to track camera changes?

Steps to reproduce
Add a component to your screen.
- Pass the following mapViewCallbacks:
<MapView
mapViewCallbacks={{
onCameraMoveStarted: (reason) => {
console.log('Camera move started:', reason);
},
onCameraMove: () => {
console.log('Camera is moving');
},
onCameraIdle: () => {
console.log('Camera is idle');
},
}}
onMapViewControllerCreated={setMapViewController}
/>-
Interact with the map by dragging or zooming.
-
Observe the console
Expected vs Actual Behavior
<MapView
mapViewCallbacks={{
onCameraMoveStarted: (reason) => {
console.log('Camera move started:', reason);
},
onCameraMove: () => {
console.log('Camera is moving');
},
onCameraIdle: () => {
console.log('Camera is idle');
},
}}
onMapViewControllerCreated={setMapViewController}
/>The following logs should be printed during user interaction:
- Camera move started: [reason]
- Camera is moving
- Camera is idle
Code Sample
<MapView
mapViewCallbacks={{
onCameraMoveStarted: (reason) => {
console.log('Camera move started:', reason);
},
onCameraMove: () => {
console.log('Camera is moving');
},
onCameraIdle: () => {
console.log('Camera is idle');
},
}}
onMapViewControllerCreated={setMapViewController}
